useless
The free version is useless.
The URL limit was reached. The Link Checker has not checked your whole website.
The URL limit was reached. The Link Checker has not checked your whole website. You can buy a token for the Link Checker Professional to check up to 500’000 URLs. Thank you for wasting my time !
500 links limit
the 500 links limit is too little for any website.
