Feed: Google - Google Shopping campaign monitoring and optimization tactics

In order for a Google Shopping campaign to be successful, it must be regularly monitored and optimized. Checking on the campaigns daily is crucial, although not every check-in needs to be in-depth. For quick daily check-ins, there are some red flags to look out for. Let’s go over the top three to give you the best chance at remedying them:

  • Zero or low impressions, which is often caused by a bid that's too low, low quality score, weak ad relevance, low CTR, expected CTR, or a bad landing page experience. 
  • If there are impressions but no clicks, that usually means that although Google is serving your ads, shoppers aren't clicking, which could be due to visible factors in the ad preview such as title, price (usually because it's too high), or image. 
  • Clicks but no conversions - This is almost always a result of the landing page and checkout process. Does the landing page inspire buyer confidence? How easy is it for shoppers to check out? Do new visitors have to create an account before being allowed to make a purchase? Is shipping not free? All these elements might affect whether shoppers commit to buying.

Analyzing campaigns weekly for heavy traffic and monthly for light traffic is recommended, in order to identify trends and establish benchmarks in the early stages of the campaign.


Conversion Rate

Conversion rate can be a simple yet powerful metric. It tells you how effective your Google Shopping campaigns, landing pages, and overall strategy are.

Formula: Conversions / Clicks


Average Order Value

AOV is one of the most telling metrics when measuring the profitability of your Google Shopping campaigns. It will tell you which products are the biggest drivers of revenue.

Take the total amount of revenue divided by the number of orders during the same period. Use this formula to determine the AOV of the channel, brand, SKU, category, and any other product grouping important to your store.

Formula: Average Order Value = Total Revenue / Number of Orders Taken



Successful retailers know the secret is not just in selling. It’s in selling profitably. The first guard against unprofitable selling is managing your cost.

For online retailers, this often comes down to measuring costs accrued by individual verticals (i.e., sales channels, brands and even SKUs).

Tip: Use GoDataFeed’s cost analytics to cut up reports based on these metrics. This will make it easier to get a transparent look at your Cost without the need for expensive ecommerce analytics solutions.


Cost-of-Sale Percentage

Cost-of-Sale Percentage (COS%) is the actual total cost of converting an item relative to the revenue it generated. For example, if one item with a $100 price tag sold and took $15 in click costs to convert, the COS% for that item at that point is 15%.

Unfortunately, you have to have a sale first in order to get this value. So what happens when a product has not sold yet? (See estimated cost of sale percentage below.)

Formula: COS% = Click Costs for Product / Product Revenue


Estimated Cost of Sale Percentage

GoDataFeed’s ECOS% preempts cost of sale to avoid running up the tab on Cost of Sale for products that haven’t acquired a sale yet but are already accruing ad spend.

ECOS% fills in the blank for COS% for products that have yet to convert. This provides a reliable predictor of what the actual COS% might be assuming the next click is a sale.

Tip: Pay close attention to ECOS% data and take action on products that don’t sell before they eat into profits from products that do sell.


Cost Per Order/Cost Per Acquisition

CPA tells you how much you’re spending on average to achieve a sale.

Say your monthly ad spend on Google Shopping is $5,000 and with that, you’ve acquired 202 sales. Your CPA then would be $24.75.

It is vital to measure CPA in relation to AOV to determine your Google Shopping campaign’s profitability.

Use GoDataFeed’s analytics tools to create CPA and AOV reports for Google Shopping to monitor CPA.

Formula: Ad Spend / Orders


Return on Ad Spend

ROAS tells you how much revenue your campaigns are generating in relation to your campaign spend. In other words, for every dollar invested in Google Shopping, how much money did you get back in revenue?

Use GoDataFeed’s cost reporting feature to measure ROAS in your Google Shopping campaigns and cut this report by SKU to identify which products are your big sellers (and which are just costing you money).

Formula: (Revenue – Cost) / Cost

Continually monitoring your campaigns and taking the appropriate actions to optimize is the only way to ensure profitability in Google Shopping.
