Duplicate title tag
What this means
Another crawled page uses exactly the same title tag, so the two pages compete for the same queries instead of each ranking for its own.
How to fix it
Write a distinct title for each page that names what only that page covers, or consolidate the pages if they genuinely address the same topic.
Fix effort
This check is auto-fixable: the change can be written and validated automatically, so CrawlX can open it as a pull request for review.
