Advantages of text link advertising
- Discrete: advertising links are placed in the sidebar, similarly to an usual blogroll, occupying a small space. Some programs offer you the possibility to include the paid links directly in your posts, but without those obtrusive embedded pop-ups.
- Not limited: there is no limit of how many advertising links you put on each page. Actually your common sense is the limit.
Drawbacks of text link advertising
- Not compliant with Google (the search engine): selling links implies also that you pass PR to the advertisers (as all current programs don’t allow no-follow tags on paid links), and this is not accepted by Google. If they catch you, they will penalize your site.
- The in-posts variant is not compatible with paid reviews because links to third party sites are not allowed.
List of text link advertising programs
Text-Link-Ads: besides the text links selling, TLA has an affiliate program which pays $25 for each person you refer and who installs and keeps the TLA code on his blog for at least 7 days. The affiliate program does not break Google’s rules, so it is safe to use it.
TNX.net: instead of using real money, TNX uses points for trading links. Points can be exchanged for USD at a rate which may vary over time.
LinkInTxt (Linkworth): unlike TLA, which gives you a plugin for handling the links, with Linkworth you’ll have to add the links by hand. All other options they claim to have did not function in my case.
