How to choose and use these tools
- Write a title and description that accurately describe the page, then preview the snippet. Search engines can rewrite either field.
- Generate structured data only for visible content. Validate it against the requirements of the relevant search feature.
- Check canonicals, language alternates and robots.txt before publishing. Use UTM parameters for campaign reporting, not as separate indexed landing pages.
Worked example
For a JSON formatter page, describe formatting and validation in the title. Point its canonical at the stable tool URL. A campaign link such as ?utm_source=newsletter should still canonicalize to that same URL.
Frequently asked questions
Will FAQ schema give my tool a rich result?
Do not expect a FAQ rich result for a utility site. FAQ markup should describe the questions and answers people can read on the page. It is not a promise of extra search features or better rankings.
Does robots.txt prevent a page from being indexed?
Not necessarily: a blocked URL may still be known from links. Use an appropriate noindex directive on a crawlable page when exclusion from results is the goal. A canonical is a consolidation signal, not an access restriction.
