@tedster I have three ways to make link building:
- Link exchange with other websites related with the same topic, always I try to do no reciprocal links. I mean, A --> MyWebsite , MyOtherWebsite --> A. My websites only share adsense code, each one have different IP/server/content. It is about: 60% of my linkbuilding
- Link exchange with my websites: I have around 100 websites with the same topic. PR 2 - PR 4. My websites only share adsense code, each one have different IP/server/content. 20% of my link building.
- Partnerships with newspapers: In my niche I can offer a white label of my product to the newspaper. Once they added product in his domain, automaticaly they add a link in the partners section located in the footer of his newspaper website. About 20% of my strategy.
As well, there are natural links with social sharing.
I'm not very regular doing link building, I don't if it matters.
I hope that this information will be thankful for somebody.
