Google AdWords Conversion Tracking for Ecommerce

Google AdWords Conversion Tracking for Ecommerce

You can't optimize anything unless you know what parts are working and which aren't. 

This is Part 2 in a Series of Articles by Ex-Googler Anton McCarthy.

In this article you're going to learn the basics of Google AdWords Conversion Tracking. We'll cover what it is, how it works, and why you need it for your ecommerce store. Imagine this: You have an ecommerce store, and you use Google AdWords to drive traffic. You're spending part of your marketing budget on clicks each week, and you control your costs using your daily budget via your campaign settings. You let the campaign run for two weeks, and you check your online sales stats regularly over this period. At the end of the two weeks, you do a final tally of your  sales, also checking how many clicks you received on your ads and how much you spent on these clicks. You have your sets of numbers in place, except there is one small problem – you don’t know how many of these clicks translated into sales on your website!

Seems crazy, right? You wouldn’t pay a mechanic to fix your car if you didn’t know what they had fixed! So, why would you spend money on AdWords clicks without somehow tracking the return on and value of these clicks?

There is an answer – and it comes in the form of a free tool that you can find in your AdWords account called Conversion Tracking. Conversion Tracking allows you to track the return on investment (ROI) of the clicks on your ads, by letting you know if a click can lead to an action on your website that you deem to be of value. These actions are called ‘conversions’, since they help translate or ‘convert’ a click into a valuable business outcome.

Specifically, a conversion could consist of one or more of the following:

  • An online purchase;
  • An inquiry or lead via your contact form;
  • A newsletter sign-up;
  • A whitepaper download.

Why Track Conversions?

In addition to the fact that it makes sense to know the value of what you're spending on your AdWords clicks, tracking conversions also allows you to delve into the specifics of what's working in your AdWords campaign. So, not only can you track the overall ROI of your clicks, you can also track the following important elements:

Specific keywords that lead to a conversion: This allows you to identify which keywords are the most valuable to you, as well as the keywords which are providing less value. Using this crucial information, you can make more informed decisions around the structure of your campaigns.

The value of a conversion at a keyword level: Since you can identify which keywords lead to a conversion, you can also cross-reference the value of each conversion with the amount spent on clicks for each of those keywords. For example, let’s say you spent one dollar on Keyword A, and it resulted in a purchase worth ten dollars. You now have a piece of data that allows you to assess the value of that specific keyword over time. This means that you might assign greater budget to campaigns that contain similar keywords, or introduce more variations of that keyword in order to explore whether similar terms with lower average costs-per-click result in an even greater number of conversions and rate of return.

How Does Conversion Tracking Work?

The good news is that Conversion Tracking is free and really easy to set up. It simply involves inserting a snippet of code on the landing page that a visitor reaches after they have completed a conversion. So, this could be the ‘Thank you for your purchase’ landing page, or the page that thanks them for signing up to your newsletter. Google AdWords supplies this code for you to paste on the relevant pages of your site, and you can get this code as you proceed through the sign-up steps for Conversion Tracking.

An ecommerce merchant may want to track purchases of iPhone cases on their online store. In this case, the site owner would paste the snippet of code onto the page the customer lands on after purchasing an iPhone case. In practice, the following is a typical channel from click to conversion:
1. Customer clicks on an ad for the online store, following a search on iPhone case;
2. Having clicked on the ad, the customer browses the website and makes a purchase;
3. With Conversion Tracking in place, this purchase is recorded as a conversion against the relevant keyword ‘iPhone case.’

Counting Conversions

You may ask – how does Google track conversions in terms of clicks? In other words, if someone clicks more than once on my ad, but they only make one purchase, how is this measured? The answer is that Google records two types of conversions:

1. Conversions (1-per-click): This is where one conversion is recorded for each AdWords click resulting in a conversion within 30 days. What this means is that a limit of one conversion is recorded per click – conversions that occur after the first are not counted. For example, if a customer clicks an ad and makes a purchase on Monday, and then returns within 30 days to make another purchase, only the first conversion will be recorded. This metric is a good option to choose for conversions like contact form inquiries, where the value of the conversion tends to originate from one unique action.

2. Conversions (many-per-click): This metric will track all conversions that occur within a 30 day period following a single AdWords click. It is a useful option for conversions like purchases, where each one is of value every time it happens.

Conclusion

I hope that this article shines a light on how Google AdWords Conversion Tracking works, and more importantly - why you should start using it today if you do not already have it in place. If you're not assessing the impact of your AdWords spend, you're just guessing - and this is far from helpful when deciding whether to continue with your campaigns, or when looking for additional marketing budget. It may well be that your spend is bringing you lots of sales and providing great value in other ways, but you'll never know if you don't track it! With this free, easy-to-use tool, you can easily track your ROI and gain a really valuable insight into the true value of your AdWords campaigns.

    We have been using conversion tracking on our store and from that wd can see that a very large number of users are falling out at the screen where the funnel jumps out to the secure server.

    We feel this is because of the radical change from our store design into the secure server. We desperately need to get our page styling translated into the secure server. Please show us how?

    Thank you.

    Hi Ifraz,

    As you suggested – use the existing design and recreate it on the checkout page.

    That is quite a simple page to configure in your theme template settings.

    Hello All,

    So Ifraz, what you are saying is that you have a cart that leaves the site upon checkout? And you are losing sales that way? and for the response… are you stating to redesign the checkout so it will stay within the store site?

    Love the quote at the top of the post. The journey begins with knowing what’s working, and oftentimes more importantly whats NOT working.

    Can you tell me does the conversion tracker fire the cart checkout value to the adwords conversion tracker? If yes how does it dynamically insert?

    Conversion tracking doesn’t have to end at the sale. If your payment gateway offers transactional emails, you can track the click-through rate of the ads in your email receipts, as well as delivery statistics.

    Great article! We offer AdWords credit to our merchants, and this will help them spend it wisely.

    Kind regards,
