1. Link Variation - Built various types of links and lots of them.
2. Link Quantity - Bought a monthly plan from backlinkteam and had them build over 18,000 links over the first two weeks.
3. Link Pace - We are still building lots of high quality manual backlinks to account for link attrition.
4. Anchor Text - every link backlinkteam created included anchor text using the keywords i was wanting to get ranked on.
5. Keyword Variation - Must use lots of keyword variation but be sure to build enough links with each variation to make sure you show up in the serps for those keywords.
6. Do competitor research - this is vital to making sure you get more backlinks than your competition and better quality links.
Hope these tips help
