Offpage optimization has no doubt outranked onpage. Link popularity is the offpage factor #1 when it comes to ranking pages in Google (I think other search engines go the same way with every algorithm update). It makes next to impossible for a webmaster to manipulate search engine rankings. As a result, the search results are more relevant and the Internet users are happier.
Techniques for building links are limited, as well as the number of link types:
• natural links/ link baits (the most desirable ones),
• purchased/ rented links,
• article syndication,
• directory links,
• press releases,
• reciprocal links,
• forum signature links,
• blog comments,
• expired domains,
• and a few more.
Apparently, not all links are equal. It is up to you if you would like to allocate some of your precious time for link hunt/ exchange process or will prefer renting a few authoritative links or will keep yourself from any link trade.
I have selected a few resources (from my point – they are best resources on link popularity available on the Internet). Some ideas and points are likely to be outdated as the Internet scene and search engine algorithms change at a fast pace, but the links are worth checking:
