What this html language checker checks
Checks the lang attribute on the <html> tag, the Content-Language header and any hreflang alternates.
The html language checker reads the lang attribute on the html element, validates it against language code format and checks whether it matches the language of the visible text. It also looks for hreflang alternates and reports where the two disagree.
Why use a html language checker
The language declaration helps screen readers pronounce text correctly, helps browsers offer translation and helps search engines show the page to the right audience.
Owners of bilingual or tourism sites, and anyone using screen reader users as a real audience. The html language checker is a thirty-second fix with a clear benefit.
How to use the html language checker
- Paste the full address of the page you want to test into the box at the top of this page. Use the exact page you care about, such as your home page or a service page, because each page can give a different html language checker result.
- Press the button and wait a few seconds. The tool fetches the page the way a visitor and a search engine would, then runs its checks. Nothing is installed, and you only need to enter your name and email to read the full result.
- Read the verdict and the plain-English notes, make the changes listed under the fixes, then run the test again to confirm the problem is gone. Keep a note of the date and the result so you can show progress.
How to read your html language checker results
- Pass means a valid lang such as en or en-KY that fits the content.

- Fail means no lang attribute.
How to fix problems the html language checker finds

Html language checker for Cayman Islands websites
Cayman Islands English follows British spelling, and the region code for the territory is KY, so lang="en-KY" is valid and accurate. Many sites ship with en-US by default. Run the html language checker and set the value that matches your audience.
Ranking in the Cayman Islands is a local contest: Google treats a .ky domain as aimed at the territory, and it rewards pages that name the places people search for, such as George Town, Grand Cayman, West Bay and Seven Mile Beach. After you act on your html language checker result, work through our SEO guides for Cayman businesses, read how the WebGuru features fit together, or see the pricing for the full report.
Cayman Islands local SEO checklist
- Name the place in your headings and first paragraph: George Town, Grand Cayman, West Bay, Cayman Brac or Little Cayman, whichever you serve.
- Keep your business name, address and phone number identical on your website, Google Business Profile, Facebook page and local directories.
- Use a .ky domain where you can. Google treats country-code domains as a signal that your audience is in that country.
- Add a Google Business Profile, ask happy customers for reviews and answer every review.
- Write for local questions, such as hurricane preparation, work permits or ferry times, in the words your customers would use.

Frequently asked questions
What does the lang attribute do?
It tells browsers, screen readers and search engines which language the page is written in.
Do I need hreflang?
Only if you have the same content in several languages or for several countries.
Does the lang attribute affect SEO?
Google mostly detects language from content, but lang helps browsers pick fonts, hyphenation and translation prompts and helps screen readers pronounce text correctly.
