First off I HOPE this is in the right spot. I wanted to share an experience I had with one of my site in hoping someone could shed some light on why this happened. I am running a wordpress MU site and I have my primary blog with 5 sub blogs. On my primary blog I simply put one article on and that is it. I linked to my 5 sub blogs from my primary and fully developed them with roughly 60 articles on each blog. I noticed that I was barely receiving any traffic at all, maybe 1 or 2 visits. (I have built similar blogs before that had less articles and more traffic) After I developed the sub blogs I went ahead and put 55 articles on my main blogs and BAM.... traffic started flowing in to ALL blogs including my sub blogs. It seemed like sense my primary blog was sitting dormant google blocked my entire site.... Maybe it was timing or maybe there is something else behind it........... Your thoughts? Note: All pages were indexed and cached before developing the main blog.
It probably has less to do with the dormancy and MORE to do with linking. Of course without your URL it's hard to tell. Google could care less if a particular page changes... They like you to "update your site" but this doesn't necessarily mean changing old pages... it's much better to add new pages. I have pages that haven't been touched in years that rank #1 for certain keyword phrases. It's hard to picure what your describing without your URL and a little more history of how it used to be compared to now. I have no clue "how" your primary blog links to the sub-blogs... But if your main blog had only one-or two links to each sub-blog because it only had a single post... and then suddenly you post 55 articles on your main blog and increase the links to the sub-blog by about 55 times what it used to be, now all of a sudden those sub-blogs might look interesting to G... worth indexing and ranking. The more "hops" or "clicks" away from the home page, the less important pages seem to appear to the engines and the less likely they are to be indexed and ranked for higher volume phrases. But you can increase the perceived importance of the page and therefore the chances of it getting indexed and ranked by increasing the number of inbound links to it.
