The Comprehensive Google Shopping Ads (Standard) Guide for the Beginner (or Anyone)

The Comprehensive Google Shopping Ads (Standard) Guide for the Beginner (or Anyone)

10/25/19 UPDATE: Hello Facebook Agency Visitor Person!  We’re delighted to have you visit this awesome post. About a year ago, ZATO stopped offering Facebook Ads solutions so we could focus solely on what we do best: Google Ads. Because of this, we’re always interested in partnerships with great Social Advertising agencies (like yourself, wink wink!) and we offer referral fees for signed clients!  Anyway, back to it, and happy reading…

Post Summary

EDIT 9/6/23: This blogpost was recently published in the prehistoric times pre-covid. A lot has changed in Google Shopping since then, so we have updated and re-released this guide including as many changes as have occurred up until this point. Enjoy!

Shopping Ads are my favorite part of Paid Search.

For anyone who works in Ecommerce paid search, having a working knowledge of Standard Shopping Ads is essential to keeping up with the competition.This article is for the purpose of giving you that working knowledge, and we’re going to do that by focusing on these 3 components to Shopping Ads:

  • Feed Setup & Management
  • Campaign Setup
  • Ongoing Optimizations

What About PMax? 

Please note, this covers Standard Shopping campaigns and not Performance Max. I've written extensively here about Performance Max campaigns, for instance with my 7 Ways to Structure Your Performance Max Campaigns. So if you're looking for PMax help, go check out some other articles. This should help give insight into how we manage the product feed, as well as Standard Shopping Campaigns.

Feed Setup & Management

In order for you to manage Shopping Ads well, you need to be aware of how they work. Shopping Ads are automated, in the sense that Google or Bing are not directly matching a search query to keywords. They are taking the data you have submitted in your merchant feed, and they are matching that to search queries.

Because of this, understanding shopping feeds is crucial to success in Shopping Ads. If you struggle to understand the concept of the feed, think of it in terms of a restaurant. Your (1) server (the data feed solution) submits your order to the (2) chef (the Merchant Center for Google or Bing), who then finalizes it and sends it to the (3) runner (Google Ads) who makes sure it gets presented to the (4) proper table (SERP).For feeds, you need to have all aspects of the process working correctly in order for your feed to be sent.

Data Feed Solution

The Data Feed Solution is how you take your product data and submit it to Google Merchant Center. There are options here, so be aware of the best fit for your particular needs.

Small Company / Low Number of SKUs - if you fall into the category of having a handful of SKUs, you can actually just use Google Sheets to integrate directly with Google Merchant Center (and it's worth noting, feed-less integration will likely become more popular with the new UI redesign of Google Merchant Center Next). This has the benefit of being simple to start and keep track of, however it’s probably not a great option if you have a lot of products (there are size limitations to this method), or if you have constant feed changes.

Large Company - if you are a good-sized company with developers to spare, then you may want to consider creating and sending your own XML file directly into Google Merchant Center. If you do go down this route, make sure you are aware of all the complexities of requirements to get your products approved, as well as ongoing changes approved.

Use Shopify? There are several Shopping Ads Feed apps that are available to Shopify brands, but our favorite by far is Simprosys. It allows you to integrate directly through the API so when you make changes to any products, they are synced automatically and immediately with Google Merchant Center. It also allows you to do a variety of bulk editing options that are not available in other apps, and for a very affordable price.

Anyone - thankfully if you don’t fall into any of those camps, there are options out there. 3rd Party Feed Providers range in size and pricing and it all depends on what you need to be done. Companies like Feedonomics are a full-service solution that can be a big benefit if you want their assistance in helping optimize, as well as send your feed. Companies like DataFeedWatch or GoDataFeed tend to be a little more affordable, but also can have less versatility and customer assistance based on that pricing. Companies like ChannelAdvisor or CommerceHub tend to have the benefit of offering other services as well (marketplaces, for instance), but do not always make sense from a cost perspective based on what they offer (watch for long, difficult to leave contracts!). Whatever you choose, be aware that you will still need to work with the feed provider to get your data to them in some format.

A word of caution: Your feed container itself is tied to your product history within Google and changing your feed can impact the performance of your Shopping Campaigns. Make sure you know what you are doing, or are working with a (good) professional (not just someone who says they know what they're doing, but doesn't...) in order to institute a feed migration. Sometimes it's actually better to leave your feed as is rather than risk harming your performance.

The Data Feed Itself

Now that you know how to get the Data Feed up, what are you actually sending to Google Merchant Center? The important thing to note about the Data Feed is that it’s important to get your product information accurate, but get as much as possible into the feed. There are required and recommended fields, and it’s tempting to only add in the required fields. However, keep in mind that Google & Bing utilize your data feed to match to search queries, so the more (accurate) data you get, the more you can potentially match up to.

Google Merchant Feed Specifications

Bing Feed Specifications

One helpful thing to be aware of when considering Bing Shopping, is that Bing accepts the Google feed directly in their Merchant Center. Importing this can save you time rather than creating a completely separate feed… unless you want to curate products uniquely for each channel.

Merchant Center

Once your feed method has been selected, you will need to send it to Google or Bing Merchant Center. These are free accounts that you can create (and verify). Ensure you fill out the requirements in business settings, tax, and shipping… otherwise they’re not difficult to get set up! Create a feed and pull from your feed provider and you’re on your way to getting Shopping Ads on Google Ads or Microsoft Ads!

Please note, Google Merchant Center is a unique entity, but Microsoft Merchant Center is currently within the Microsoft Ads UI in the top, main navigational menu.

As a tip, when you first push up a feed, it can take 24-72 hours in both Google and Bing for the feed to be approved, so be patient and don’t wait until you needed the products up yesterday to do this.

Google Ads

The final step, is to link your Google Merchant Center account with Google Ads so that your products are eligible to display.

You will need to link your Google Ads account in the Google Merchant Center settings here:

You can view this link in Google Ads in the settings (Linked accounts) section:

Campaign Setup

Once you got the feed connected and products sent (make sure to fix any product disapprovals!), you need to set up your Shopping Campaigns in Google Ads. We could spend hours and hours of discussion on this, but we don’t have time for that so I’m going to have to do less discussing, and more detailing. Here is what I have found to be key principles to be aware of for setting up a successful Shopping Ads campaign strategy.

Principle 1 - Segment Campaigns by Product Category

First, don’t just stick with a single campaign in your account, trusting the search engines to match everything up perfectly. This limits you in many ways, but primarily in bidding. Since you set bids based upon product groups, and however you have segmented those product groups out, you are in essence setting one bid for scores of queries of varying levels of intent. We’ll speak more on this in the next point.

all google shopping ads in one ad group

Initially, I would recommend segmenting out your catalogue based upon natural categories based on how your customers search, or on other factors such as product cost or success. It’s crucial to grasp the idea of controlling how you can bid as you consider setting up your Shopping campaigns.

For example, in a client with an apparel focus and high volume of brand loyalty, it may make sense to separate your campaigns by Top Brands, or at the very least by ad group so you can control bids individually.The thing to remember about segmenting categories or brands by Campaign or Ad Group, is that you can better control negative keywords and thus push queries in between campaigns or ad groups.

Example (over-simplified): let’s say that the query [blue athletic shoes] converts well in your Adidas ad group, but not in your Nike ad group. Because you have these segmented by ad group, you can exclude that query in Nike. This will prevent it from wasting spend, and push those impressions to the Adidas ad group. The one thing I’ll note with this to keep in mind, however, is to remember that be aware that you can have multiple ads showing for one Google Shopping SERP, so be careful not to over-exclude… you may be keeping competitors from showing and that may be in your favor!

Be smart about excluding, but be willing to try it.

There are lots of other ways to consider segmenting campaigns, you can segment all Top Products into a single campaign with a High Priority setting, and then put the rest of your products in the lower Tiers to ensure your Top Selling products always get first shot at impressions, regardless of bids. Whatever you do, figure out what works best for your account and get building out beyond one campaign and one ad group.

Principle 2 - Segment by Queries

I have written extensively on this elsewhere, so I won’t go too far down the rabbit hole here. The basic idea is that keywords are a form of communication, and demonstrate buying intent. This means in Search we can assign value (a CPC bid) based upon what a person is communicating through their Search Query.

You would likely be willing to bid higher on “I want to buy an awesome Force FX lightsaber with free shipping” then you would “saber” because there is buying intent in the first query.However, in Shopping Ads, you bid on a product basis. This means that the $0.50 bid you set for that lightsaber product, is bidding $0.50 on “I want to buy an awesome Force FX lightsaber with free shipping” as well as $0.50 on “saber”. Starting to see the problem?We need to be able to bid separately on query buying intent, and thankfully there is a way to do that. Using the Priority settings structure, as well as negative queries, you can pull unique query groupings into unique campaigns so you can bid separately on them.If you are interested in learning more about this, please go read my article here where I spent 4000+ words telling you exactly how to do this!

Does Google Shopping Query Filtering Still Work Beyond 2020?

Ongoing Optimizations

Phew, you made it this far. Great job! You’re basically a Shopping Ads pro now. Your feeds are set up, your campaigns are live, now it’s time to manage things.

The first thing you need to be aware of with Shopping Ads, is that you do need to upkeep them. While there is a level of automation to them, there are also many, many ways they can go wrong. Here are the top things you should focus on to keep your Shopping campaigns humming and profitable.

Query Mining

Just as in Search Ads, query mining in Shopping Ads campaigns is essential.What is query mining? I am referring to the process of going through your Search Terms report and analyzing it for keywords.The thing with Shopping, is that you can find a lot of benefit in finding both negative, as well as positive keywords.

Negative Queries

What you will find is that Google and Bing can play fast and loose with how closely they want to match your products up to user queries. Because of this, you will also see queries of varying quality flex in and out of your account.

amazon logo

As an example, just this past week I discovered the exact match term of [amazon] in an account that has been running for a decade (and I have been running personally for nearly two years now). I wasn’t selling amazon action figures or stuffed animals of creatures found in the Amazon basin. It was just a terrible match.

I recommend getting into the account regularly to mine through your search terms.

How regularly? It will depend on the size of the client, but I think you should be going through your Shopping campaign queries at least once per week… and that’s if you have a good structure and are already on top of things!

Positive Queries

Did you know you can use Shopping as a keyword research tool? Because Google and Bing are matching up your products with searches their algorithms believe to be right, they will likely find keywords you hadn’t discovered in your research phase. Keep an eye on your queries in Shopping for this reason as well, then find those top terms and built them into Search ads so you can control the SERP in text and Shopping!

One example of how you can utilize positive queries is in running Title tests. I've written more on this here, but the gist is that you can use your search terms report to identify core terms people are searching to find, and then buy your products. Then you can test those search terms in your product titles to gain additional exposure for key products on those important search terms!

How to Run a Title Test in Google Shopping

Product Curation

Product Curation is another option you have for ongoing optimization, but I would advise caution here. By Product Curation, I simply mean determining to only advertise certain products in your feed. There are a few reasons you might consider this. You may have more products than you have budget. If you have $5K per month to spend on Shopping Ads, but 200K products… you probably need to curate what you send. Or, you may have been running Shopping Ads for awhile now and have some conversion history you want to utilize in making a decision to pare back on products not selling.

How do you curate? Well it's important to send ALL your products to Google Merchant Center so you can still take advantage of free product listings, BUT then use the excluded_destination feed attribute, or use your Campaign Settings filter, or only target specific product groups within your campaigns so you ensure you're only actually advertising the products you want to be advertising.

The benefit to curating, is that you can focus your data, optimization efforts, and bidding efforts on the few products that do drive the most overall sales. If you have account history, you may consider starting to curate your feed by eliminating product IDs that have never accrued any impressions, after which you could try eliminating product IDs that have not accrued clicks. On the other hand, what if those are good products that just need title or description tweaks? The plot thickens, and proceed cautiously.

Another reason for caution here, is because Shopping Ads tend to be of higher importance towards the Top or Middle of the funnel. The last thing you want to do, is to make a decision on products with little obviously tracked revenue, that ended up being great products at starting the customer journey. You’ll strangle revenue flowing in from other sources (Brand campaigns, Organic, Direct, Social, etc) and never know that it was related to those products… so caution is needed.

Feed Optimizations

A significant aspect of Shopping Ads is the product feed, so it stands to reason that making smart adjustments to that feed would be an important part of optimization (this is especially important for the more automated Performance Max campaign type). There are several things that can be done to the feed, but when the rubber meets the road, we are busy marketers and I think there are a few easy wins to focus your energies on to get the biggest bang for your buck.

The primary thing to note in feed adjustments, is that testing is notoriously difficult with Shopping Ads since you can’t run the test simultaneously. What you will have to do, is analyze what impact normal seasonal trends (from previous years) have on the timeframes you’re running your test, and then look at KPIs such as impression share or CTR rather than volume only. I would also recommend limiting bid adjustments during your test period so you minimize variables.

Titles & Descriptions

When it comes to titles and descriptions, we must reset our brains a little and think back to old-school SEO. While this doesn’t technically mean keyword stuffing, it does kind of mean keyword stuffing. Identify the terms your searches use to purchase your products and make sure those terms get into titles and descriptions. Here is where you can do some testing. Try running titles for a certain product brand with primary descriptive keywords at the front of the title, and then run a test for another month. For example, you might try these variations of titles in testing:

  • Green Running Shoes Nike Free RN 2018 - Mens Size 10
  • Nike Free RN 2018 Green Running Shoes - Mens Size 10
  • Nike Free RN Mens Size 10 Green Running Shoes

Keep in mind for title testing, that you can utilize Google Feed Rules or Supplemental Feeds to test without having to change your feed. This can be extremely helpful in controlling your own tests as the PPC Manager without having to make a big production of getting the dev team or feed provider to assist in your test until you are ready to move forward on a larger scale.

Research Recommendation: How do you know what keywords to include in your title? From my experience, it’s easy to do some basic experiments with Keyword Planner. This may tell you to test putting “lego” before or after “millennium falcon” in your product (example below) based on what is more commonly searched for in terms of search volume.

(I'll share again my article on running a shopping ads product title test here).


Price is a crucial aspect to Shopping Ads and one that is increasingly being revealed as having a significant effect on revenue growth, as well as potentially on the algorithm itself (see this slideshare of a presentation by Andreas Reiffen, beginning at Slide 11).

andreas reiffen google shopping prices

This makes sense of course, since people are often drawn to the lowest price when given multiple options (all else being equal). This can be quite problematic for you if your store tends to be consistently higher priced (without a significant other value you provide) on Google Shopping. Worse yet, you may discover that you still get curiosity clicks followed by a bounce as that visitor heads back to the SERP and buys from your lower-priced competitor. So you ended up losing the sale AND still paying for the click.

The issue here, is that PPCers rarely directly control the product pricing. I say rarely sarcastically, because the real word is more likely “never”. There are many, many factors that factor into product pricing and you can’t control all of them… but you can have a say.

  1. I think the action for pricing is two-fold: Be aware of this as a major impact on profitability if rapid changes changes happen with little adjustments made in management. In other words, if a key product suddenly becomes less profitable or drops in sales, yet nothing major has changed strategically, that is a great time for a competitor pricing analysis. More often than not, you will find your competition has dropped prices on you which impacted your sales. Keep your radar on at all times.
  2. Be communicative with your management team regarding the crucial role Pricing plays in Shopping. Unwilling to lower pricing? Maybe it’s time for a shift in strategy since Shopping is so crucially about price, and maybe you can be the one to investigate and identify the need for that. Are there ways your business needs to think about pricing better in 2018 marketing and how it relates to Shopping Ads? It is you who will need to be aware of, and communicate the need for Shopping Ads to have a place at the pricing discussion table.


The final thing to note in terms of quick-easy wins in feed optimization is image testing. Since the image is the crucial visual part of a Shopping Ad, getting this right could benefit your traffic and sales.For various image testing suggestions and tips, I would send you to the (oldie but goodie) presentation at SMX West that Purna Virji (formerly of Microsoft Ads) gave: Thats Hot! 3 Shopping Campaign Tips That Would Make Paris Hilton Proud

google shopping images

The key tip to bring out for images in Shopping Ads, is to make them stand out. There are many ways you can do this (though make sure they are in line with Shopping Ad image policies), but the number one most common would be testing both product images and lifestyle images.

Marketing is often about distraction and catching attention, and there is a strong case to be made for testing images that disrupt your current SERPs.

Bid Adjustments

Finally, we get to the last section in this mega-long article. The final ongoing optimization in Shopping Ads that we’ll note is the topic of bid adjustments.

When I speak of making smart bid adjustments, I am thinking of two different categories. Thinking through adjustments on a micro, or product group, level and thinking about bid adjustments on a macro, or account wide, level. Both are important and I’ll detail them below.

MICRO (Bidding Models)

Overall, we most often use two bidding models within our Standard Shopping campaigns at this point in Google Ads' history: 

  • Manual bidding

There are other models that can be utilized for more advanced testing, but the vast majority of accounts will be fine utilizing one of these two.

The case for Manual (yes, I still believe there is one), is when you have a highly stable, controlled environment in which you want to maximize exposure in the SERPs without overbidding. For instance, if you have a very small brand with a tightly controlled query grouping campaigns setup, then manual bidding will allow you to maximize exposure on those Brand, and CORE non-brand Bottom Funnel terms you want to own while keeping traffic lower on the generic Non-brand terms. TROAS bidding on the other hand, is the classic ecommerce bidding model for a reason, as it utilizes value-based bidding targets to point Google's Machine Learning to find the most ideal customers for your products at your targets.


Ok, so you thought through micro-bidding… but how do you think through bidding on an account-wide basis? Here we are leaving hard data (somewhat), and journeying into the unknown.

It’s essential that you be aware of the idea of Attribution. If you are unfamiliar with that notion, I would encourage you to get my PPC Ponderings Book and read my chapters on attribution (one of them can be read here):

A Tale of Marketing Attribution Woe

marketing attribution

In attribution, we determine which channel gets the credit for the sale. Of course, the user journey is so much more complex than this, but there also needs to be some way of getting directional ideas from our attribution tracking.

The reason Shopping Ads gets messy fast with attribution, is because Shopping Ads target all stages of the funnel, but most often the middle to bottom since Shopping Ads (like Search Ads) are capturing existing demand... rather than creating it.

This is in part, why it is essential to segment your marketing campaigns according to different stages of the funnel based on query intent (see above). However, once you’ve done that, I’d like to encourage you to go one step further.

That is, as you analyze and make micro-bidding adjustments, that you do so keeping the funnel in mind. My recommendation is something like this:

  1. Pull generic, non-brand queries into a “top of funnel” campaign, and then utilize a first click attribution model to identify impact on overall sales.
  2. Pull brand, or mid-journey queries into a “middle of funnel” campaign, and utilize a time decay or position based model to analyze success.
  3. Pull SKU, or unique buying intent queries into a “bottom of funnel” campaign, and utilize a last click model to determine success and set micro-bid adjustments.

If we don’t think better about making bid decisions according to where the Google Shopping query is in the funnel, then we will be massively under-valuing Google Shopping which will only lend itself to hurting overall sales.


You made it! Congratulations. I hope you had as much fun as I did, and I hope you are better prepared to attack your Shopping campaigns!
