Robots.txt Generator: Common Mistakes and Best Practices

Most problems with robots.txt Generator aren't caused by not knowing what to do — they're caused by small, easy-to-miss mistakes that compound quietly over time. Here are the ones that come up most often.

Mistake 1: Blocking /wp-admin/ or /cgi-bin/ style paths that don't exist on your platform, copied from a generic template without checking.

Mistake 2: Disallowing CSS/JS folders, which stops Google from rendering the page properly and can hurt how it's evaluated.

Mistake 3: Assuming robots.txt is enforced — it's a voluntary convention; well-behaved crawlers respect it, scrapers with bad intentions often don't.

The fix for most of these isn't more effort, it's a regular check. A few habits that prevent them from creeping back in:
- Point to your sitemap with a `Sitemap:` line at the bottom of the file so crawlers find it without needing a separate submission.
- Test changes in Google Search Console's robots.txt tester before deploying — the file affects every crawler simultaneously and mistakes are immediately live.
