Link building is hard. I think it is the hardest part of a successful internet marketing strategy.
I wrote a few new articles on link building on the HubSpot blog. The first one talks about how to construct a good inbound link and why link building is so important. The second one talks about what methods to use to build inbound links to your site. Both articles link to a lot of other authoritative articles about blogging written by other bloggers. The first article has a lot of great comments from HubSpot blog readers who shared some link building success stories and ideas. With these two new articles, there's now a good amount of link building articles on the HubSpot blog, giving a good overview of link building best practices.
