Page speed
Who loads first on a phone. Slow mobile pages lose visitors before they read a word.

How long does a comparison take?
About a minute. Google PageSpeed runs a real Lighthouse test on both homepages, on mobile and desktop, and that is the slow part. Your speed scores appear on the page as soon as it finishes.
Is the gap report really free?
Yes. The speed scores need no signup at all. The full report needs an email address so we can send you a private link to it. There is no card, no trial and no paywall later.
What do you do with my email?
We send you the report link. Someone from Windmark may reply once to offer a walkthrough of the gaps. We will not add you to a newsletter unless you ask.
Why are my scores different from PageSpeed Insights?
Lighthouse scores move a few points between runs, because each test loads the page fresh over a simulated mobile connection. Treat a gap of more than 10 points as real and a gap of 2 or 3 as noise.
How do you find pages my competitor has and I do not?
We read each site's XML sitemap and homepage links, then sort every URL into page types such as pricing, case studies, comparisons and integrations. A page type shows as missing when your competitor has at least one and you have none.
Can I compare against more than one competitor?
Each report is a head-to-head against one site, which keeps the gaps specific. Run the tool again for each competitor you want to check.
