This isn't the usual software you download and install. It doesn't stand on its own because it needs a platform to be implented on, Google Chrome. It's actually an extension.
It is a tool mostly used by site developers and those who have to edit a lot of sites that have many references. Web designers and those who take care of content editing have also been very grateful for this.
This is the description of one of the most popular one.
It's very annoying to click on a link and see that it isn't working because it is either broken, the website is down, the page has been removed or the hosting shut.
What this extension does is it checks links on your webpage, going top to bottom, and looks for those that are broken, don't work anymore for some reason.
It's a very quick way to check the site's quality. Imagine clicking on each link manually. How annoying would that be for someone who appreciates their time?
This software is quick and goes through you page in detail. It checks each link and highlights all of them, the ones that are valid turn green and the ones that for some reason aren't (or are very suspicios) turn red.
That gives you a visually understandable scheme of what the current situation looks like.
The HTTP response codes and those full URLs of the links that have been highlighted red can later be found in the Console log which kind of works like the history portion of Chrome too.
What's great about it is that it is constantly being updated with new content and improved so there are no bugs. It works with local files too.
It has an interesting option of „alerts“ for empty href attributes that may have been overlooked, as well as railing #s and anchor tags.
All of the invalid links can also be put into the console in CSV format so you can export it and take the report with you if needed.
You can also check rel=“nofollow“ links if you wish. The software works by the GET request method and you can also pick those links that will always be considered valid no matter how many times you run the whole proccess.
If you wish, you can just check the invalid ones and ignore the ones considered green if you want to be quick. This is important because it saves time.
There are a lot of settings on cache and local files, HTTP Request Types and the blacklist. If you wish, you can skip certain links like the Adsense links and so on.
Point being, you can totally personalize the whole software so it fits you perfectly.
