What a website checker actually tells you
A website checker is a diagnostic tool. It crawls a page the same way a search engine would, measures what it finds against known best practices, and reports the gaps. Think of it as a health check — it does not fix problems, but it tells you exactly what needs attention and how urgently.
The value is not in the score itself. A grade of B means nothing in isolation. The value is in the prioritised list of specific, fixable issues that sit behind that score. A single missing canonical tag or a render-blocking stylesheet can suppress an otherwise strong page.
The five dimensions of website health
SEO fundamentals
Search engines rely on structured signals to understand what a page is about and whether it deserves to rank. The most important signals are also the simplest: a unique title tag under 60 characters, a meta description that earns the click, a clean heading hierarchy that reflects the page's content structure, and a canonical URL that prevents duplicate content issues.
Most websites get these right on their homepage and wrong everywhere else. Product pages, blog posts, and category pages are where SEO fundamentals break down — and where the traffic opportunity is largest.
Page speed
Google has used page speed as a ranking factor since 2010, and Core Web Vitals became a formal ranking signal in 2021. The three metrics that matter most are Largest Contentful Paint (how fast the main content loads), Cumulative Layout Shift (how much the page jumps around during load), and Interaction to Next Paint (how responsive the page feels).
Speed problems are almost always caused by a small number of issues: unoptimised images, render-blocking CSS or JavaScript, slow server response time, or excessive third-party scripts. Fixing the top two or three issues typically moves the needle more than chasing a perfect score.
Mobile usability
More than 60% of web traffic is mobile. Google uses mobile-first indexing, meaning it evaluates the mobile version of your site for ranking purposes. A page that works on desktop but fails on mobile is a page that will struggle to rank.
The most common mobile issues are viewport configuration errors, text that requires zooming to read, tap targets that are too close together, and horizontal scrolling caused by fixed-width elements. These are straightforward to fix but easy to miss without a systematic check.
Security
HTTPS is a baseline ranking signal — Google confirmed this in 2014. Beyond the certificate itself, modern security best practices include HTTP Strict Transport Security (HSTS), a Content Security Policy (CSP), and X-Frame-Options headers. These do not directly affect rankings, but they protect your site and your visitors, and their absence signals neglect to both browsers and search engines.
Structured data
Schema markup helps search engines understand your content and can earn rich results — review stars, FAQ dropdowns, product pricing, and event details displayed directly in search results. Pages with rich results consistently earn higher click-through rates than plain blue links.
Our checker detects existing schema markup, validates it against Google's requirements, and identifies schema types you should add based on your page content.
From diagnosis to action
A website check is step one. The report tells you what is wrong and how to prioritise fixes. For most businesses, the top five issues in the report will account for the majority of the opportunity. Fix those first, re-check, and iterate.
If the fixes require technical implementation — server configuration, CMS changes, or codebase modifications — that is where our SEO team comes in. We audit, prioritise, and implement, so you are not left with a report and no path forward.

Frequently asked questions
What does the website checker test?
Our grader runs checks across five categories: SEO fundamentals (title tags, meta descriptions, headings, canonical URLs), page speed (load time, Core Web Vitals, render-blocking resources), mobile usability (viewport configuration, tap targets, font sizing), security (HTTPS, HSTS, content security policy), and structured data (schema markup presence and validity).
How is the website grade calculated?
Each category receives a score based on the number and severity of issues found. These are weighted — SEO and speed carry the most weight — and combined into a composite grade from A (excellent) to F (critical issues). The weighting reflects how much each category affects real-world search performance.
Is the website checker free?
Yes, completely free with no account required. You can run as many checks as you like.
How often should I check my website?
We recommend running a check after any significant change to your site — a redesign, CMS update, new plugin, or content migration. For ongoing monitoring, monthly checks catch regressions before they affect rankings.
What should I fix first?
Start with the issues marked as high priority in your report. These are typically missing or duplicate title tags, slow server response times, missing HTTPS, or broken structured data — the issues most likely to be suppressing your search visibility right now.
