What the SEO and developer tools do
The SEO and developer tools help you prepare a website for search engines, AI answer engines and social sharing: write meta and Open Graph tags with a live preview, make share images, build robots.txt files and JSON-LD schema markup, check keyword density, read cron schedules and tag links with UTM parameters.
They run in your browser, so drafts, client sites and campaign plans are never sent anywhere.
Use them while you build or audit a site: write the title and description for each page, check how a link will look when shared, tell crawlers what to skip, add structured data so search engines read your business details correctly, and tag campaign links so you know which posts bring visitors.
Questions
Will these tools improve my Google ranking?
They help you get the basics right: clear titles and descriptions, valid structured data and a robots.txt that doesn't block important pages. Rankings still depend mostly on how useful your content is.
Do I need schema markup to appear in AI answers?
No. Google says there is no special schema markup you need to add to appear in AI Overviews or AI Mode. Schema markup still helps search engines read facts such as names, prices and dates, and it should always match what the page shows.
Is anything I type sent to PageYak?
No. The tools work in your browser tab, so your text, URLs and keywords stay on your device.
Do I need to know code to use them?
No. Fill in the boxes and copy the result. Each tool explains where to paste the code.
