dislike404.com is a one-person hobby project and currently runs entirely out of my own pocket.
At some point I may add some simple ads to help cover the server costs - but that's it

There are a few things worth checking:

• Does your robots.txt file exclude our bot?

• Are you using a CDN like Cloudflare that might be blocking the crawler?

• Have you set up a blacklist entry that might be too broad?

• And is your website actually reachable and the URL correct?

• You can also check the "Not Scanned" tab in your scan details to see why specific URLs were skipped

If none of that helps, feel free to contact me.

The most common reason is that our bot is being blocked by a security measure or CDN like Cloudflare.
Since our bot identifies itself, you may be able to whitelist it by name or by our IP address 5.9.153.60

If you need help with that, just get in touch.

This can have several reasons:

• It might be a temporary issue - in that case it will likely resolve itself on the next scan.

• It could also be a real error on the external website

• Some services like Amazon or Instagram simply block bots by default.
  Since the dislike404.com bot identifies itself as such, there's nothing I can do about that.
  You can add these URLs to your personal blacklist to keep them out of your scan results.

We maintain a global blacklist of sites that can't or don't want to be scanned.
We also respect each site's robots.txt.

If you think a URL has been blacklisted by mistake or you'd like to suggest an addition, feel free to contact me.

Yes – the bot follows all redirects, both internal and external.

If the redirect target is an internal page, it will also be scanned for errors and its links will be checked as usual.
If the redirect ends up on an external page, we follow it to verify the target is reachable - but we don't crawl any further from there.

Both URLs will appear in your scan results – the original URL as HTTP 30x and the target URL with its actual status code.

With the blacklist, you can exclude individual sections of your website or external websites from being scanned.

This can be useful if, for example, the external website blocks bots or if you do not want certain areas of your site to be checked.
You can access the blacklist via the blacklist button in your website control panel.
You can exclude exact URLs or use the wildcard character *, which matches zero or more characters.
A few examples:

• Exact URL: https://example.com/dont_scan_me.html

• Both http and https: http*://example.com/dont_scan_me.html

• Entire path: http*://example.com/dont_scan_me/*

• Subdomain: http*://dontscan.example.com*

• Entire domain:*example.com*

Each scan has two limits: internal pages (any page on your website with actual content) and total requests (every asset we check along the way - images, scripts, stylesheets and more).

• Unverified: up to 200 internal pages and 1,000 total requests

• Verified: up to 50,000 internal pages and 500,000 total requests

Need higher limits? Just send me a message.

Verification proves that you actually own the website you're monitoring.
Once verified, you unlock higher scan limits and additional options.
Verification is free and takes just a few minutes.

Verification works by uploading a small text file to your web server. The exact steps and your personal verification code are shown directly in your dashboard once you add a website.

The file needs to be accessible at the root of your domain - for example yourdomain.com/dislike404-verification.txt.
That means you need to be able to upload files to your web server.

WordPress users
Upload the verification file to the root directory of your WordPress installation. The same folder where wp-config.php is located.
You can do this via FTP, SFTP or your hosting provider's file manager.
Do not put the file inside wp-content or any other subfolder.
