Your search title is often the first sentence someone reads about a page. A clear title tells them what they'll get, while the description gives them a reason to open it.
Use the snippet preview to compare drafts before publishing. It shows an approximation of a result on desktop and mobile, so you can spot awkward wording and likely cutoffs.
Say what the page helps someone do
For a JSON tool, JSON Formatter & Validator Online | Eleventor names the task and the publisher. A matching description could be:
Format and validate JSON, find syntax errors, and copy or download the result.
Check that the page actually offers every feature you mention. A specific description helps someone decide whether the page meets their need.
Avoid filling the title with related keywords. Repeating "JSON tool, JSON editor, JSON formatter" leaves less room to explain what the visitor can do.
Read both previews
Enter the title, description and page URL. Look at the desktop and mobile versions, then read them as someone who hasn't seen the page.
Does the opening make sense? Is the brand repeated? Would someone still understand the main task if the final words were cut off?
Character counts can help you compare drafts, but letters have different widths and search layouts vary. Don't remove a useful detail just to reach a particular count.
Expect the live result to differ
Google can choose text from the page instead of using your description. The snippet can also change with the search query, as its snippet documentation explains.
Make the page introduction and headings clear too. They help readers after the click and can provide text for search results.
The preview doesn't check indexing, fetch the live page or measure rankings. After publishing, inspect the actual HTML for your title, description and canonical URL. Check that the page is accessible and isn't accidentally marked noindex.
Review results after publishing
Keep a note of the old wording, the new wording and the date you changed it. In Search Console, review queries, impressions, clicks and click-through rate over a useful period.
Compare similar periods and look at changes in position and search queries. More clicks after an edit don't prove that the title caused the increase.
Revise the wording when you can make the promise clearer or better match what people are looking for. The aim is a result that accurately represents the page.
