Best Link Building and Analysis Tools

Link building has become a staple of search engine optimization (SEO) campaigns, not least due to Google originally being a links-based search engine using it's (in)famous PageRank algorithm. Although Google and other search engines now take into account other major factors as part of their ranking criteria, such as human user data and semantic processing, link building remains a cornerstone of any good SEO campaign.

It used to be the case that SEO's would try to get links from anywhere, swapping, buying, even hacking, to get them. However, these days the importance of links is less about their keyword anchor text as much as providing an incentive for users to click, such as to find out more information or for discounts on a useful product.

This means that link the building is now much more focused on generating traffic directly, which means a need to find targeted users in already existing traffic streams related to your needs. Finding them manually is a challenge, but luckily there are automated tools that can help identify websites and webpages that may be relevant to your own needs, and therefore worth chasing for a relationship.

Link building remains hard work and easy short cuts are unlikely to deliver significant benefits. But if you can identify useful link sources, you have a chance to put your products/services/brand in front of people you might otherwise find hard to reach, helping improve your marketing efficiency and ultimately even your ranking positions on search engines.
