SEOTyde

SEOTyde is a Chrome and Firefox extension for checking on-page SEO while viewing a webpage. Click its toolbar icon to get a score based on signals such as the title, meta description, headings, image alt text, canonical tags, and robots directives. It also previews how the page may appear in Google results and on social media, and reads page speed and weight from browser performance data. The audit brings several checks into one view: it scans internal links for broken destinations, highlights keyword density, and reports a Flesch readability score. To compare pages, you can enter another URL and view its score beside the current page. Scans are saved locally so you can revisit a page’s history, and results can be exported as Markdown for sharing or client reporting. The extension runs its scoring in the browser without an account or signup. Page content is not sent to a server, and the product says it makes no AI calls. Its workflow suits people who want a quick review during writing, publishing, or page updates without setting up a separate crawl.
