Keyword Density Checker
Keyword Density Checker online — accurate, standards-compliant and free for SEO work.
Fill in your page title, description, keywords and author, and get a clean block of HTML head meta tags to paste — title, description, viewport and robots included. It builds live as you type, in your browser.
Your browser is preparing the tool. It runs 100% locally.
Type a page title, meta description, keywords and author, and the tool outputs the matching HTML head tags — a title tag, a meta description, a viewport tag and a robots index, follow tag, plus keywords and author tags if you fill those fields. Everything is HTML-escaped and updates live. One honest note up front: the keywords meta tag is included for completeness, but Google has ignored it since 2009. It all runs in your browser.
Enter your details and copy the generated block straight into the head of your page. You always get a title tag, a meta description, a viewport tag (width=device-width, initial-scale=1) and a robots tag set to index, follow; the keywords and author tags appear only if you fill those fields. Special characters in your text are escaped so the markup stays valid.
It is a formatting helper, not an analyzer — it does not score your title length or count your description. Its job is to turn four plain inputs into correct, paste-ready head tags without you hand-writing the markup and attributes.
As you type, the tool assembles the tags in a fixed order and HTML-escapes each value — ampersands, angle brackets and quotes become entities — so a stray character in your title cannot break the markup or the surrounding page. Empty optional fields are simply dropped, so you never paste a blank keywords or author tag.
The viewport and robots tags are added every time because almost every page wants them: the viewport tag makes the page render correctly on phones, and index, follow tells search engines the page may be indexed and its links followed. Both are safe, standard defaults.
title — your page title
meta description — your summary text
meta keywords — only if you fill the keywords field
meta author — only if you fill the author field
meta viewport — width=device-width, initial-scale=1 (always)
meta robots — index, follow (always)The keywords and author tags are omitted when their fields are blank; the viewport and robots tags are always added.
| Inputs | Title, description, keywords, author |
|---|---|
| Always output | title, meta description, viewport, robots (index, follow) |
| Conditional output | keywords, author — only if filled |
| Escaping | ampersand, angle brackets, quotes become entities |
| Description length | not counted or enforced |
| Live | updates on every keystroke |
| Where it runs | In your browser — nothing uploaded |
The keywords meta tag is generated if you fill the field, but it does nothing for Google ranking (ignored since 2009) and Bing can read it as a spam signal. It is included for completeness and legacy systems; you can safely leave the field blank.
It does not check your title or description length. Search engines show roughly 50 to 60 characters of a title and about 155 of a description before truncating, and Google rewrites titles often — so keep the important words first. A separate counter or SERP preview is the place to check fit.
It always sets robots to index, follow. If a page should be kept out of search, change that tag to noindex yourself after pasting — the tool does not offer that toggle.
The output is a flat block of head tags. It does not add Open Graph or Twitter Card tags for social previews; those are separate generators.
Values are escaped for safety, so a character like an ampersand appears as its entity in the output. That is correct HTML and renders as the original character in the browser.
Generate the core head tags for a fresh page without hand-typing each one.
Fill the head of a hand-coded or templated page quickly and consistently.
See exactly which tags belong in the head and how they are written.
Produce a correct meta description or robots tag to drop into an existing page.
Want social share previews? Use the Open Graph and Twitter Card generators. Need to check length or how it looks in Google? Use a SERP snippet preview or meta-description counter. Adding structured data? Use a schema generator.
Outputs the standard head tags with your input HTML-escaped; it includes the keywords meta only if you fill that field, and is upfront that Google has ignored keywords since 2009.
