Website Grader: Quick Performance, Mobile, SEO and Security tests

Website Grader is an Internet service to grade websites based on core metrics such as performance, mobile support, search engine optimization and security.

The service is without doubt not the most complete application of its kind, but it is fast and provides actionable advice when it finds issues that can be fixed to improve the overall grade of the website.

All you do is type or paste a URL that you want to check and hit the "get your answer" button afterwards. The email field displayed prominently on the site is optional.

The tests start and should not take longer than a minute to complete. If there is something to criticize, it is the complete lack of progress indicators. You are bombarded with quotes during that time though.

An overall score, a rating in words (this site is good), and individual performance, mobile, SEO and security scores are displayed near the top.

A click on a score scrolls down to the section detailing what is good, okay, and not so good about the site.

For instance, you may see there that the page size is quite okay but the number of page requests are not.

Website Grader runs seven performance tests in total that test a website's size, HTTP requests, loading time, browser caching, page redirects, compression, and render blocking.

Each entry offers a short explanation and a "read more" link to find out what you can do about a particular issue (or what you have done right).

The mobile test checks whether the site is reponsive, and whether the site's viewport is properly configured for mobile visitors.

The SEO test is a bit of a let down, as it checks only four on-page metrics. It checks the page title length and keyword repetition, the meta description length and relevancy, whether headings are used, and whether a sitemap is linked in the source.

Finally, security checks whether the site supports SSL certificates.


Website Grader is not as technical as Google PageSpeed or YSlow, but it is ideal for a quick test as it checks several core metrics. It is a handy tool thanks to it being fast and efficient.

It appears however that Website Grader is not working for all sites right now, and that it may come to inaccurate conclusions at times especially when it comes to mobile support.

      Well it is a bit difficulty to distinguish between domains and files for instance.

    @Ashwin–Thankful you delighted my comment; who knows how many “gamers” would have disagreed!

    The comments section under this very article (3 comments) is identical to the comments section found under the following article:

    Not sure what the issue is, but have seen this issue under some other articles recently but did not report it back then.

    With the cloud, there is no such thing as unlimited storage or privacy. Stop relying on these tech scums. Purchase your own hardware and develop your own solutions.

      This is a certified reddit cringe moment. Hilarious how the article’s author tries to dress it up like it’s anything more than a png for doing the reddit corporation’s moderation work for free (or for bribes from companies and political groups)

    With Google Chrome, it’s only been 1,500 for some time now.

    Anyone who wants to force me in such a way into buying something that I can get elsewhere for free will certainly never see a single dime from my side. I don’t even know how stupid their marketing department is to impose these limits on users instead of offering a valuable product to the paying faction. But they don’t. Even if you pay, you get something that is also available for free elsewhere.

    The algorithm has also become less and less savvy in terms of e.g. English/German translations. It used to be that the bot could sort of sense what you were trying to say and put it into different colloquialisms, which was even fun because it was like, “I know what you’re trying to say here, how about…” Now it’s in parts too stupid to translate the simplest sentences correctly, and the suggestions it makes are at times as moronic as those made by Google Translations.

    If this is a deep-learning AI that learns from users’ translations and the phrases they choose most often – which, by the way, is a valuable, moneys worthwhile contribution of every free user to this project: They invest their time and texts, thereby providing the necessary data for the AI to do the thing as nicely as they brag about it in the first place – alas, the more unprofessional users discovered the translator, the worse the language of this deep-learning bot has become, the greater the aggregate of linguistically illiterate users has become, and the worse the language of this deep-learning bot has become, as it now learns the drivel of every Tom, Dick and Harry out there, which is why I now get their Mickey Mouse language as suggestions: the inane language of people who can barely spell the alphabet, it seems.

    And as a thank you for our time and effort in helping them and their AI learn, they’ve lowered the limit from what was once 5,000 to now 1,500…? A big “fuck off” from here for that! Not a brass farthing from me for this attitude and behaviour, not in a hundred years.
