Test your pages/sites

Passmarked tests how well your website works based on the most up-to-date web standards and best practices contributed by the global coding and web standards communities.

How does it work?

Well, when you run a test on Passmarked, you will instantly receive a report card that tells you the overall test score for the web page or website you’ve submitted, as well as scores for each of the four test criteria. These scores can help you to track progress over time. In each category you will receive immediate alerts on all critical errors, non-critical errors, warnings and notices related to issues within that test category. The report is sharable and if you sign up for a free account, you’ll be able to save and scan up to two websites on your dashboard. If you need more you can explore other packages that offer monitoring and support.

A Passmarked test tells you how well your site scored based on these four criteria:


See the exact size, browser rendering speed and major HTML health issues of your page or site.


Find out how well your site adapts to different devices, and what CSS, HTML and Javascript issues may be plaguing your site.


Get an instant overview of how well your site performs in terms of Search Engine Optimisation (SEO), spelling and grammar, and the effective use of social links and other hyperlinks.


Instantly receive specific warnings about issues relating to HTTP configuration, SSL certification or malware that may jeopardise the security of your site.

Fix issues with an extensive knowledge base

A Passmarked test report not only tells you about all the issues with your page or site, it also provides you with helpful tips and links so that you can fix those errors in no time. Everything you need to know about fixing website errors using the latest web standards and best practices is indexed in Passmarked’s extensive Knowledge Base - a large dedicated Wiki-style library on website issues and fixes, for the community, by the community. It’s the not-so-secret weapon in our crusade to fix the internet, one broken website at a time.

Monitor continuously for any new issues

If you are taking care of just one or two small websites, it should be easy enough to manually monitor and track their performance on Passmarked over time. If however you are taking care of a large corporate site, busy eCommerce site or a multitude of complex sites, chances are you will be needing more robust, automated, around the clock monitoring and alerts about important issues that may pop up at any moment.

Passmarked offers two main monitoring options: the Pro option for basic monitoring and alerts for up to 10 websites, and the Business option for an unlimited number of smaller websites, which is ideal for agencies and freelance developers taking care of a few client sites. For the really big guys there is the Enterprise option. Here we can tailor personalised plans to provide enterprise-grade website monitoring, alerts, emergency support and customised business solutions.
