What the website performance checker checks
Performance is more than speed. A page can load quickly and still lose visitors and rankings because of broken links, missing tags or a poor mobile layout. The checker audits each area that affects how users and search engines experience your site. The Web Page Audit runs 179 on-page checks; the free check on this page scores your page for the keyword you enter.
Speed and server
- Loading speed: how quickly the page loads for visitors.
- Page response times: how quickly the server responds to requests.
- Server and security: server configuration and security checks that can affect trust and crawling.
Usability
- Mobile usability: whether the page works well on phones and small screens.
- Broken links: links that lead visitors and crawlers to dead ends.
On-page SEO and content
- HTML tags: the title, meta description, headings and other key tags.
- Content quality and duplicates: thin or duplicate content that weakens a page.
- Outgoing and incoming links: how the page links out and how it is linked to.
- Social tags: how the page looks when it is shared.
- Hreflang and pagination: signals for multilingual and multi-page content.
How to use the website performance checker
Enter the page URL
Start with your most important pages, such as the home page, top service pages and pages that bring in leads.
Add a target keyword
The on-page part of the audit checks how well the page targets the keyword you want it to rank for.
Run the audit and review the results
Your score and top issues open free. Work through the issues by area, starting with speed, server and broken links. A free account opens the full report.
Download or share the report
Export a white label PDF report with your logo and colours, in any of 12 languages, and send it to your client or team.
Fix and re-check
After you make changes, run the checker again to confirm that the issues are resolved.
How to read your results
Group the issues into three buckets and work from the top down. One audit is a snapshot: re-check pages after releases, redesigns or plugin updates, because performance problems often return after site changes.
For a complete technical review of an entire domain, follow our comprehensive guide to auditing and fixing technical SEO issues across all pages.
- Fix now: slow response times, server or security errors, broken links and serious mobile usability problems. These hurt every visitor and can stop search engines from crawling the page properly.
- Fix next: slow loading caused by heavy resources, and missing or weak HTML tags. These affect both rankings and click-through rates.
- Improve over time: content quality, duplicates, link structure, social tags, hreflang and pagination. These raise the overall quality of the site.
Step-by-step fixes for every result
Each issue in the report has a short How to fix. For the full steps, with menu paths for WordPress, Shopify, Webflow and Wix, open the guide for its area.

Website performance checker FAQ
What does a website performance checker do?
It audits a web page and reports problems that slow it down or hurt its search visibility, including loading speed, page response times, mobile usability, server and security, broken links and on-page SEO.
Is website performance the same as page speed?
No. Page speed is one part of performance. A full check also covers server response, mobile usability, broken links, HTML tags and content quality, because all of them affect how visitors and search engines experience a page.
How often should I check my website’s performance?
Check key pages after every major change, such as a redesign, new theme or plugin update, and on a regular schedule, such as once a month. Re-checking confirms that your fixes worked and catches new problems early.
Can I send the results to my clients under my own brand?
Yes. You can download the results as a white label PDF report with your agency’s logo and colours and share it with clients. Reports are available in 12 languages.
Can I check a whole website, not just one page?
Yes. The checker audits one page in depth. To find issues across a site, use the site crawl, which checks up to 1,000 pages.
Is the website checker free?
Yes. Enter a URL and keyword in the form at the top of this page: your score and top issues open free, without sign-up. A free account opens the full report, and the 14-day free trial includes every feature with no credit card.
