I would like to make my own Broken Link Algorithm In PHP can you guide me i see many seo reporting site providing this but i want to create my self can anyone guide me please ?
What you need to do is check the links, and parse the return value - if it's 200, the link is fine, if it's anything else (301, 302, 404, 500) there's an error, and you can report based on that. You could do this in pure PHP, although an AJAX-call might be preferable as it would provide a per instance load while waiting for the complete list to be processed.
