How To Check For Broken Links
Having a well maintained website improves your users experience as well as improving your reputation with the search engines. Google for example can crawl a broken link and if you have a lot of broken links it can harm your reputation with google which in turn will damage your search engine position.
As search engine optimisation becomes a big aspect of having a successful website, google refines its algorithm to help keep its results relevant to the users search term, which means more work for the website owners. Everything on your website has to be 100% search engine friendly if you ever want to make it big in google, and having 404 errors and broken links will damage any prospects of competing with the big names.
There’s this really good wordpress plugin which will check through your links and tell you which ones are broken and which ones are redirecting.
I suggesting using this tool as even the most experienced blogger some times makes mistakes.
