Fix Your Product Feed

Google Shopping isn’t magic. What you get out of it depends on what you put into it. Simply put, Google Shopping campaigns won’t succeed without first making your product feed successful.

In our years managing client campaigns, we’ve seen it all when it comes to product feeds. Here are our best practices for optimizing your product feed!

Verify Product Feed Data

Ensure data is up-to-date and formatted correctly. Google requires some fields, so make sure those attributes exist across all products.

Map to New Feed

Map the existing product fields to the new feed, making a note of the incorrect attributes you found in the audit.

Fix Common Errors

Fix product feed errors you found. Common issues include missing GTINs or incorrect field values.

Segment Products

Choose how to segment your products. The most important factor is margin, which should always be included. Other options include category, price tier, and more.

Identify Top Products

By identifying and segment top performing products to ensure those products aren’t dragged down by under-performing products.

Sync Product Feed

You need to update and re-sync the feed to Merchant Center regularly, so Google is always working with the most up-to-date version of your product feed.

Segment Your Products

Above, we noted the importance of segmenting your products into different campaigns and ad groups. There’s a fine line here. Separating products too narrowly means products won’t drive enough traffic to make meaningful bidding decisions. However, segment too broadly and it’ll be impossible to draw conclusions about segment performance, because so many products are included.

Here are four common attributes we use to segment products for Google Shopping.

Google Product Category

Product category is the most obvious candidate for segmentation. Products in the same category tend to have similar performance trends, and category is a useful dimension for performance reporting.

Cost of Goods

Cost of Goods is the single most important way to segment your campaigns. Grouping products with the same margin allows you to track the profitability of segments and ad groups, and to spend at a level that allows for maximum profit overall.

Price Tier

Price is an important segmentation factor because it greatly impacts not only ad spend, but how customers purchase your products. Higher-dollar or luxury items often have a longer sales cycle, which you’ll need to take into account when evaluating performance.

Item Performance

Item performance is extremely important for segmentation. By identifying and separating the top selling items, you can be more aggressive with bids for these items than with others, since you know they historically sell well. Likewise, segmenting weak items prevents their underperformance from affecting other products.

Google Shopping Best Practices

Apply Query Segmentation

Segmentation extends beyond products. It’s also extremely important to segment search terms as well, according to how likely the search term is to create a sale. Once you have the terms sorted, you can apply them as negative keyword lists, driving the maximum amount of spend or traffic to the terms that are the most likely to convert.


Pull Search Term List

The first step to segmenting your search terms is to know what they are, and how they perform. Start by pulling the list of search terms for your campaigns from Google Ads. Ideally, you’ll need at least six months to a year of historical data to have enough information to properly segment terms.


Run Ngram Analysis

The next step is to determine the relative value of each of the terms. This is easily accomplished with an ngram analysis. This analysis takes search terms, their cost, number of conversions, and revenue generated and determines which one, two, and three word phrases are the most successful. Once this analysis is completed, you can use it to find the relative value of the search terms in the list.


Segment Queries

Segment these keywords according to their value: high, middle, and low. The ngram analysis discussed above helps, but you can also sort terms by hand or use an alternate system (as long as it’s data-driven.)


Apply Negative Keyword Lists

Apply the lists to the appropriate campaigns. As long as bids are also tiered, this process will ensure the right amount of spend is directed to terms according to their likelihood of conversion. The most generic terms will receive a much lower bid, while the middle terms receive slightly more and the highest-converting terms receive the most spend.

Apply Profit-Based Bidding

Profit-driven management is a best practice for Google Shopping.

Most agencies and in-house marketing teams optimize Google Shopping campaigns against metrics like ROAS, ROI, A/S, or CPO/CPA. These are great metrics for measuring efficiency: but they won’t offer the best opportunity to maximize profit.

The above metrics won’t account for business-critical considerations like cost of goods and variable overhead. As a result, these metrics really only offer a partial picture of performance. Campaigns that seem like they have really good ROAS results—even 12x or more—could in fact be running unprofitably. Instead we recommend using profit.

Google Shopping Best Practices

Track the Right Google Shopping Metrics

The secret to truly profitable, successful campaigns? Taking a data-driven approach to managing those campaigns. It’s impossible to manage an account to profit effectively if you have no idea what is actually happening in the account.

That also means putting metrics in proper context, too. Metrics shouldn’t be viewed in a vacuum. Each one is part of a much larger picture of account performance. A dip in revenue isn’t always cause for alarm – sometimes, this dip is associated with a short-term cut in spend intended to bring the program to profitability. In these cases, a slight decrease in revenue can actually result in additional profit produced.

Here are four metrics that are commonly either misinterpreted – or simply not tracked at all.

Average Order Value

Average order value has a number of implications for account performance. An increase in this metric can justify an increase in ad spend and/or cost per order. It also may provide important context to a drop in sales. For example, if you’ve recently redirected spend to focus on larger sales that come at a slightly higher price point, a small dip in sales isn’t a big deal. A drop in AOV that is accompanied by an increase in cost or a dip in sales, or both?That’s possibly cause for concern and definitely worth investigating further.

Revenue per Click

Revenue per click is the amount of revenue generated in a time period divided by the number of clicks needed to produce it. Like AOV, revenue per click offers important insights on account performance. If revenue per click increases, you can justify an increase in ad spend per click, which done correctly will produce even more revenue.

If you can do all this while controlling costs (by reallocating ad spend toward more profitable search terms, for instance), profit will increase!

Conversion Rate

Conversion rate is a valuable metric to track because – for starters – improving it is a great way to increase revenue per click. Conversion rate trends can also provide early warning for site usability or pricing issues.

Contribution Margin

Contribution margin is the percentage of revenue that flows to profit. Tracking this metric – which takes into account both efficiency and sales volume – is the best measure of profitability for your program. Every program will have a different ideal benchmark for this metric, which is based on available margin.

Google Shopping Best Practices

Optimize, Optimize, Optimize

Google Shopping best practices don’t end with launching campaigns. There are a series of ongoing optimizations you should make to ensure your campaigns are the best they can possibly be at all times. These improvements range from product feed attribute changes to modifications to device placements. Here are some analyses you can run, to find the insights you need to continually improve your program’s performance!

An example of a title optimization spreadsheet. Optimizing product titles using profitable terms is a Google Shopping Best Practice.

Title Optimization

Although updating product titles before you launch Shopping campaigns is a best practice, title optimization should also be an ongoing process. As your advertising drives sales, that data can help continually rework titles to increase click-through rate and conversion rate.

A title optimization analysis looks at product titles and compares those titles to the terms that drive sales for those products. These often include descriptive terms, style descriptors, and synonyms.  For example, a furniture retailer with a “yellow sofa” can have successful terms like “mustard yellow loveseat sofa.”


Device Modifiers

It’s also important to optimize Google Shopping campaigns according to their device. Ideally, a device optimization analysis standardizes the rate of return across devices. In other words, a dollar of ad spend produces an equal rate of return – no matter which device the dollar is targeted toward.

For example, if desktop ads average a 25% rate of profit, you should adjust bids to achieve that same rate of profit across mobile and tablet.


Dayparting Analysis

For any retailer, different times of day hold different levels of efficiency. Conversions are just more likely to convert some times than others, and not all days and times will be efficient. By analyzing conversions for each hour of the day and each day of the week, you can adjust bids to drive spend to days and times when traffic is most likely to convert.
