If you are one those whiney bloggers who is always complaining about your Technorati link counts then this post from Technorati should explain it for you. A blog's Technorati rank is based only on inbound links from the past 180-days.
In other words, the numbers in the green box reflect activity in the last 180 days, while the number of links directly below the green box is the total for as long as we have data.
The 180-day window means that ranks and link counts go up and down. Some bloggers see their counts rise steadily when others link to their blog. In the chart below, we see 200 days of linking to www.perezhilton.com. For purposes of ranking and comparison, we count only those links in the last 180 days (those in the red box.) Perez' counts are going up. Yay!
So, basically you are only as good as your last 180-days. Poor Strumpette. Her link count is down because the surge of inbound links she received from her blog's debut occured over 180 days ago. You can see on this graphic how Iran President Mahmoud Ahmadinejad's blog is going to suffer from a big drop in rank when the thousands of inbound links he received from his blog's launch passes the older than 180-day mark.
You can chart your own inbound link graphic by using this url and
substituting your blog url for the text BLOGURL. You can change the days, width and height figures as well
