Questions
Is the site grader really free?
Yes. Grade as many sites as you like, yours or your competitors', and get every report by email. You don't need a Yclas account, and we don't add you to a newsletter.
What does the grader check?
Over 40 checks in four scored areas. SEO: title, description, headings, indexing, robots.txt, XML sitemap, structured data, social previews, image alt text, content crawlers can read. Speed: Google Lighthouse on a phone, real-visitor Core Web Vitals, server response time, compression, page weight, render-blocking scripts, CDN. Trust: HTTPS, contact, privacy and terms pages, safety tips, reviews, social profiles, security headers. Mobile: viewport, responsive layout, zoom, phone-friendly fields, home-screen icon, apps. It also checks the marketplace basics: search, a clear way to list, categories, listings with prices and how fresh the content is.
How is the score worked out?
Each check passes, needs work or fails, and counts in its area by how much it matters: a site that tells Google not to index it loses far more than one without a favicon. A check we can't measure is left out rather than counted against you. Each area is scored out of 100, and the overall grade is their average.
Why is my speed score different from PageSpeed Insights?
The speed score combines Google Lighthouse's mobile score with real-visitor data and our own measurements (server response time, compression, HTTP/2, CDN, image formats). Lighthouse scores also vary from run to run by a few points.
Can I grade a competitor's site?
Yes: the grader only reads public pages, like a visitor or a search engine would. It's a quick way to see where you are ahead, and what to fix first to overtake them.
Does it work for directories, job boards and rental sites?
Yes. The checks are made for sites where people list things and others browse them: classifieds, marketplaces, business directories, job boards, real estate, vehicles and rentals. It grades any public website, but the advice is written for those.
What happens to my email address?
We send you the report, and the Yclas team can see that you graded a site. We don't sell it or share it, and every email has an unsubscribe link.
Rather start from a site that scores well?
Yclas builds classifieds, marketplace and directory websites with HTTPS, an XML sitemap, structured data and mobile-ready themes from day one.
