Hello Friends, increase to back links of site, i think the more effective activities are forum Comments, blog comment, and directories .
You need a combination of everything possible to make it look natural. as vertexplus said - a mix of those things - and high quality article marketing is useful as well as online PR, guest blogging, and homepage links. Make sure you focus mainly on the homepage but also the subpage that's most relevant!
I second that. Variety is the key. Vary everything up, where you get the link from, what anchor text you use, where you link to.
Hello friend, If your site content is relevant,you can get lots of quality backlinks. posting in forums,blogs,article submission,press release and also do other activies to get quality backlinks, not a single one activity.
I believe that every backlinks work differently. For fast indexing, use social bookmarks. To build up the PR and the positions of the grant using article submission, press release. Well, better to use properly the natural links that put you on other resources.
To get quality backlinks submit to directory and bookmarking websites with relevant keywords, description and category.
You should have a combination of: blog comments, directory, social bookmarks, forum signature link, etc. But they should be relevant
