A few months ago we started an experiment to build our own bookmarking sites on previously aged, high PR domains to see how they performed. We built just over 30 of them and the pattern seems to have been the same for most – they kept their PR for a little while and then it dropped to zero which isn’t terribly useful.
PR0 links are not generally considered useful unless in really vast quantities and we’d rather have a smaller number of good sites with PR then a large number of PR0 sites so for the moment we’re considering the experiment unsuccessful and we plan to remove the sites from the system in due course but we will try and incorporate some new sites as we do so to keep the links flowing.
We have also seen the Article sites steadily drop – these seem quite short lived in some cases but thankfully there seem to be lots of article sites around that work on templates which are easily incorporated into IMAutomator so we are likely to do one big push like we did a few months ago to add another 20 or 30 sites to the system in one batch.
Directory sites are another area that we are looking at, and we have quite a few on our lists now that are ready to be incorporated but we’ll work on the other types first.
Lastly RSS sites – we haven’t found any new ones in a while that don’t require a CAPTCHA solving for submission. As these can only be solved with a paid system such as Decaptcher, we need to add support for this before we add more of those sites and the cost for that will need to be passed onto the member.
