There are a number of free tools that are available online in order to check the backlinks to a particular website. These backlink checkers usually query the respective search engine services via their exposed APIs to get link back information. However, most of them do not present the details retrieved in a way that we can understand them and consume for further link building.
This is where LinkDiagnosis comes handy. Using this online tool and its addon for Firefox you can get a detailed view of the backlinks to your site and get information such as PR of the linking page, link strength, keywords used, relation property of the link etc.
Main features of LinkDiagnosis
The following are the main features supported by LinkDiagnosis:
Detailed Backlinks check (Link Diagnosis)
You can use this feature to dig into the details of your back links for anchor tags used (keywords) for linking, quality of the link (good/bad), link strength, page rank, total links from the linking page etc. It takes a few minutes before the tool fetches in all the data (after your enter your URL) but it’s worth the wait. The backlinks data that it fetches in can be sorted as well as exported to CSV format. This is an amazing way to find out the wrong keywords used while building links and more importantly to find your competitors’ backlinks etc.
Link Diagnosis requires a Firefox add in order to render all its analytical information. The analytics that it shows include the Page rank distribution, link types analysis etc.
Site diagnosis basically scans your sitemap.xml and provides you information on those pages that are ‘good’ in Google’s books. Good pages essentially means those pages that are actually well indexed by Google and has a valid PR. This is a simple mechanism to check all your internal pages that have valid PRs.
This is a feature that you can directly invoke from your browser using the context menu while you are on a web page. Somehow, this part has not been giving proper results for me.
Overall Link Diagnosis a great handy tool to help you with your link building and SEO Optimization!
