I know a lot of people out there have started using LinkAuthority. I have been using it for some time now, and have noticed a trend that can help you get a little more out of the network.
Over the past few weeks, it seems that on the weekends the time it takes to get an article approved increases dramatically. Most days, I will have an article approved in just a few hours. Sometimes up to 5-6 hours, but still not bad. On the weekends, there have been times I have submitted a post to the network, only to see it not approved until sometime late Sunday night or, on a few occasions, not until Monday. The network gives you a daily quota of posts that can be published depending on how much you pay and/or how many sites you have submitted to the network. If you are trying to take full advantage of your quota, this can lead to problems.
For everything the network does, I really am not complaining. I have found a simple solution that has worked so far. The review process is a manual process, but it seems to me that the posting is a more automated process. What I have started doing is loading up and submitted a whole bunch of articles (basically my quota for Friday, Saturday, Sunday) and submitting them all on Thursday.
The result is that they all get approved before the weekend and get queued for posting. Up to your quota each day will get posted, without having to hope somebody reviews them on the weekend. Just a simple way to make the most out of the network.
