Not sure if a page is excluded by your robots.txt file? The Index/No Index app will parse HTML headers, meta tags and robots.txt and summarize the results for you. If no matching rule is found, DatayzeBot assumes it is allowed to crawl the page. DatayzeBot will follow the longest matching rule for a specified page, rather than the first matching rule. To specifically allow (or disallow) the crawler to access a page or directory, create a new set of rules for " DatayzeBot" in your robots.txt file. You can get around the cap by pausing the crawler and resuming it another day.ĭatayzeBot now respects the robots exclusion standard. Since the DatayzeBot does not index or cache any pages it crawls, rerunning the Website Validator will count against your daily allowed number of page crawls.
