Unfortunately, these errors mean that the website's server has denied access to our crawlers for security purposes.
​
​NOTE: Some sites deploy highly protected security measures to prevent all automated crawlers. Except for Google crawlers.. of course!
​
If you see this issue, AND you own the site ( or have access to its servers )
then you can try to whitelist our crawler by selecting :
​

1. Click Advanced Settings > Include Custom ##### HTTP Header
2. this will show your UNIQE header ID.
3. copy/paste that into your server configs.
​
This will generate a unique header ID *value assigned just to your account/crawlers.
