Website Optimization: Speed, SEO, and Conversion

Frequently asked questions

What should a website optimisation agency improve first?

High-traffic, high-intent pages where speed or UX friction is measurably blocking conversion. That intersection matters: high traffic alone means you can measure a change but not that it is worth anything, and high intent alone means it matters but you cannot detect the difference. Starting where both are true gives you a result fast enough to fund the next round of work.

Do Core Web Vitals guarantee rankings?

No, and treating them as a ranking lever leads to disappointment. They are quality signals that act as a tiebreaker between comparable results; content quality and relevance still dominate. The honest reason to fix them is that they measure real user experience, and users who bounce off a slow page do not convert regardless of where you rank. Improve them for the users, and take the search benefit as secondary.

How long before optimisation work shows impact?

Directional signals in two to six weeks, a result you can trust over a full quarter. The gap exists because conversion data is noisy, seasonality is real, and most sites do not have the traffic to reach significance quickly. That is also why running one change at a time matters more than shipping fast: several simultaneous changes on thin traffic leave you unable to attribute anything.

What does a credible 90-day plan look like?

Instrument, test, scale, in that order. The first month goes on getting the funnel measured properly and fixing the critical speed and UX problems that need no testing to justify. The second runs focused tests on the pages that matter. The third scales what won and addresses the drop-off clusters the data exposed. A plan that starts with a redesign has the sequence backwards, because it changes everything at once and leaves nothing attributable.
