Frequently Asked Questions
Should I Block TextRazor Downloader?
Usually not. Blocking TextRazor Downloader may leave shared links without a title or image, making them less inviting to click. If it begins fetching at unexpected volume, try rate limiting before blocking it outright. Almost none of the top websites we track currently have robots.txt rules for TextRazor Downloader.
Does TextRazor Downloader Follow Robots.txt Rules?
No. TextRazor Downloader is not expected to follow robots.txt rules, so a disallow rule only communicates your preference. Enforce the block with firewall or server rules, then use Agent Analytics to verify that its requests stop.
Does TextRazor Downloader Access Private Content?
No. TextRazor Downloader has no credentials and should access only the public URL and assets needed for a preview. It does not continue through the rest of your site.
How Can I Tell if TextRazor Downloader Is Visiting My Website?
Agent Analytics tracks TextRazor Downloader visits in real time. You can also check your server logs for requests whose user-agent string contains "TextRazor Downloader". Look for a page and its preview assets being requested without follow-up navigation. Because TextRazor Downloader does not publish a verification method, any client can claim its identity and a log match is only a clue.
Why Is TextRazor Downloader Visiting My Website?
Someone shared a link to your page. TextRazor Downloader fetched it to build a preview card, and each new share may trigger another request. A spike often means your content is circulating more widely.
