Paste any page from your site and we’ll check the 12 on-page basics that search engines read first. You see your score and biggest issues straight away, and your email opens the full list.
Check a page
Reads your page’s HTML the way a crawler does
Each check below covers something a search engine looks for before it decides whether to show your page. Here is what we test and why each one matters to a small business.
We check that the page answers with a normal 200 OK status when a browser or crawler requests it. Pages that return an error or a missing-page code drop out of search results, however good the content is.
We check that the page loads over a secure HTTPS connection rather than plain, unencrypted HTTP. Browsers warn visitors away from insecure pages, and Google treats HTTPS as a ranking signal.
We look for a robots meta tag, an X-Robots-Tag header or a robots.txt rule that blocks search engines. A single leftover noindex tag from a site launch can hide every page from Google.
The title tag is the clickable headline Google often shows in search results. We look for 30 to 60 characters, which is long enough to describe the page without getting cut off.
The meta description is the short summary that can appear under your link in search results. We look for 70 to 160 characters, since a clear summary helps win the click without changing your ranking.
The H1 is the main headline on the page, and it should say what the page is about. We look for one, because pages with none or several send search engines a muddled signal.
A canonical tag tells search engines which address is the main version of a page. Without one, copies of the same page at different addresses can split the credit between them.
The viewport tag tells phones to fit the page to the screen instead of shrinking a desktop layout. Google uses the mobile version of your site for indexing, so a missing tag hurts in two places.
The lang attribute tells browsers, screen readers and search engines which language the page uses. That information helps Google show the page to the people who search in that language.
Open Graph tags supply the title and image for the preview card when someone shares your link. Without them, links shared on Facebook, LinkedIn or WhatsApp appear without a picture.
Structured data is JSON-LD code that describes your business in a format search engines can read. We check that it exists and contains valid JSON, but we don’t validate the schema itself.
Alt text is a short written description of an image that screen readers speak aloud to blind visitors. Search engines also use it to understand pictures, and decorative images can have an empty alt.
Every check gets one of three results, and the color tells you how urgent it is.
Your score weighs each check by how much it matters, so it isn’t a simple count. Page response, indexing and the title tag count three times as much as alt text. One blocking problem therefore pulls the whole score down.
Start with any Fix under page response or indexing, because those two decide whether Google can show the page. Then move on to titles, descriptions and headings, because they shape how your listing looks in search results.
When you press the button, we fetch the page the way a search engine crawler does and read its HTML. We also read your robots.txt file to see whether it blocks crawlers from that address.
We don’t run JavaScript, so text that only appears after scripts load won’t count toward your result. Google can run JavaScript, but content that depends on it can take longer to reach the index.
Titles that are missing or too long are easy to fix, because every major platform lets you edit them. On WordPress, use the SEO title field in a plugin such as Yoast or Rank Math. On Shopify, edit the search engine listing on any page or product, and on Wix, open the page’s SEO settings.
Meta descriptions live in the same place as the title on WordPress, Shopify and Wix. Write one plain sentence that says who the page is for and what they get, in under 160 characters.
A noindex tag often survives from the weeks before launch, when the developer hid the site on purpose. On WordPress, go to Settings, then Reading, and untick the box that asks search engines not to index the site. On Wix, check that each page allows search engines to index it in its SEO settings.
Many themes style the logo or a banner as an H1, which leaves the page with two main headlines. Keep one H1 that names the topic of the page, then use H2 headings for each section below it.
A missing preview image is easy to fix and makes every shared link look more trustworthy. Shopify lets you set a default sharing image in your online store preferences. Most WordPress SEO plugins add a social tab where you can choose the image for each page.
