Measuring SEO
SEO without measurement is slow and expensive. You make changes, publish content, build links - but without data you cannot tell what is working, what is wasting your time, or whether you are moving in the right direction at all. Measurement is what turns SEO from activity into a strategy.
There is an important distinction worth making at the start of this chapter. Metrics track activity inside search engines - organic traffic, keyword rankings, click-through rate, backlinks. KPIs (key performance indicators) show whether that activity leads to business outcomes - leads, purchases, signups, revenue. As TapClicks summarises it: metrics show progress, while KPIs confirm results. Both matter, but they answer different questions. You need to be watching both, not just one.
Backlinko's guidance on SEO measurement is direct: total organic clicks from Google Search Console should be your primary north star. If that number is consistently going up over time, your SEO efforts are working. If it is flat or declining despite ongoing work, something in the strategy needs to change. Everything else in this chapter supports that core question.
What this chapter covers
- Key SEO metrics - the specific numbers you should be tracking regularly, what each one tells you, and where to find them. Covers organic clicks, impressions, average position, click-through rate, organic conversions, and Domain Rating - including which matter most and which are vanity metrics worth keeping in perspective.
- Rank tracking - how to monitor keyword positions over time, the right way to interpret ranking data, and why a single ranking check tells you far less than a trend. Covers how to set up tracking in Search Console and Ahrefs, and the common mistakes that make rank data misleading.
- Organic traffic analysis - how to use Google Analytics and Search Console together to understand not just how much organic traffic you are receiving, but which pages it is landing on, whether those visitors are engaging, and whether they are converting. The difference between traffic that counts and traffic that just shows up.
- SEO audit - how to run a structured audit of your site's SEO health, what to look for, how to prioritise what you find, and how to turn an audit into an actionable plan rather than a list of problems with no clear next steps.
The tools covered in the previous chapter - Google Search Console, Google Analytics, Ahrefs, and Semrush - are the platforms you will use to access most of this data. If you have not set those up yet, start with the Search Console page before working through this chapter.
