Conversion (CRO): the complete guide.

Eleven chapters to turn more visitors into leads and customers: method, conversion paths, landing pages, forms and pre-launch QA.

The essentials · 30-second read

CRO turns more of your existing visitors into leads or customers. This guide gives the method in eleven chapters.

  • Define what counts as a conversion before you measure it, then track it as a key event in your analytics (chapter 1).
  • Diagnose before you test: analytics, session recordings and user feedback show where visitors drop (chapters 1 and 2).
  • Every page needs one obvious next step: a good-looking site without a conversion path still loses leads (chapters 4 and 5).
  • Give each campaign its own landing page; Google Ads also rates landing page experience as part of Quality Score (chapters 6 to 8).
  • Check forms, tracking, speed and mobile before paid traffic goes live (chapters 9 and 10).

ChatGPTPerplexityClaudeGeminiGrok

More traffic is not always the answer. When visitors arrive but do not act, the problem is often the page itself: an unclear offer, a weak next step, a form that asks too much or a tracking setup that hides what really happens.

Conversion rate optimization (CRO) is the method to find those blocks and fix them in the right order. This guide gathers our articles on the subject: the method first, then the site's conversion paths, landing pages, forms, and the checks to run before you pay for traffic.

FAQ

Questions about CRO.

Write to us
What is a good conversion rate?
There is no universal benchmark: it depends on the sector, the traffic source, the offer and above all what you count as a conversion. A demo request and a newsletter signup cannot be compared. The useful reference is your own rate, measured on a stable definition, by page and by traffic source, and how it moves after each change.
Do I need A/B testing to do CRO?
No. A/B tests need enough traffic to give reliable results, and many B2B sites do not have it. Below that level, work from qualitative evidence such as session recordings, user tests, sales feedback and form analytics, then ship the obvious fixes. Note that Google Optimize, once a common testing tool, has been unavailable since 30 September 2023.
Where should I start?
Find where visitors drop. Define your key events in analytics (form sent, demo booked, purchase), look at the pages that bring traffic but few conversions, then watch a few sessions on them. Fix the clearest issues first: the message at the top of the page, the call to action, the form and the mobile display.
How many fields should a form have?
As few as you need to qualify and answer the request. Each extra field is one more reason to leave, so ask whether you really use the data. Label every field clearly, show errors next to the field concerned and test the form on mobile. The W3C forms tutorial covers labels, instructions and error messages in detail.
Should ads point to a landing page or the home page?
A landing page, in most cases. It matches the promise of the ad, removes navigation that distracts and lets you measure the campaign on its own. Google Ads also rates landing page experience as one of the three components of Quality Score, alongside expected click-through rate and ad relevance.
Can CRO hurt SEO?
Not if it is done carefully. Changing a headline, a call to action or a form does not harm rankings in itself. The risks come from removing content that ranks, hiding text behind scripts or slowing pages with heavy testing tools. Check that tested pages stay indexable and fast, and keep SEO and conversion goals in the same brief.
