Internet is a very dynamic environment if you think about it, it’s constantly changing, new websites go online and some old sites will be gone even if they have important information.
If you have a blog or a website you know that from time to time you will post some links inside your posts and if you come back in a few months, weeks or even days you will find few of these links being broken for what ever the reason. In order to make sure that you will not disappoint your visitors you will have to check every links in your site’s content to find and remove these broken links which like broken promises to the client will make them not trusting your site in the future.
One of the easiest ways to do this is to use a WordPress Plugin that will automatically check all the links in all posts and pages of your site and will send you an email letting you know that how many broken links are in your website, in addition you have the ability to have a widget on your dashboard that will show you the result of this link checking that is done automatically and without any further intervention from you.
You can find Broken Link Checker from here or by searching the WordPress plugin depository. as for the installation it could not be any easier all you ave to do is to install using the install plugin section of WordPress and then activate it.
