.edu and .gov backlinks are said to hold more weight with search engines compared to regular domains such as .com and .net. This is because EDU backlinks are a lot harder to get than other links and are seen as more trustworthy.
Learning how to find and build links on EDU and GOV sites can help you achieve a good search engine position for your chosen keywords much more easily. One thing you must bear in mind is link building should appear natural to search engines. This means the websites to which you post your links must be relevant and do not post to LOADS of sites, just hand pick a few.
The easiest sites that allow you to link back to your website are ones that will allow you to post comments, like blogs and forums. Here is what you enter into a Google search to find these sites, not forgeting to change “ADD YOUR KEYWORD”.
site:.gov “add comment” OR “post comment” “ADD YOUR KEYWORD”
site:.edu “add comment” OR “post comment” “ADD YOUR KEYWORD”
site:.gov “powered by vbulletin”
site:.edu “powered by vbulletin”
So to summarise, EDU & GOV links can have positive effects on your website’s search engine optimisation. But, and it is a big BUT, you must be careful where you post links and how many you post. Ensure that you post links to websites that are relevant to yours, do not spam and choose a few websites with care.
