I am running a very small spam test to setup a much bigger test later this week or next week. I'll update the thread a couple times over the next week or so if any significant changes happen. Test Site Stats Age: 5 month old site Competition level: Very Difficult Indexed Pages: 5, all 100% unique and 500+ words per post Pre Panda and Penguin Rankings: Page 10 Post Panda and Penguin Rankings: Page 5 Last SEO Work Done: January So this site actually moved up significantly after the most recent updates even though no work has been done to it nearly 4 months. The Test 20k blog comments via scrapbox using 54 different anchors including more than 30 generic anchors such as "click here". Day 1 So far today the site has slipped down to page 8. I can't wait to see if this is the beginning of a dance or if I killed a site that Panda and Penguin loved for a grand total of $5. Day 1 continued... just a few hours later and it is now at pos 147 Update: Still sliding back, now 155. Day 2 Considering how fast my ranking was dropping yesterday I expected to wake up today and see I had plummeted out of the top 1,000 but I am still holding at 155. I was bouncing around between 55 - 57 before so I wonder if I incurred a -100 penalty or if I'll take another jump at the next data refresh. I'll update again upon next movement.
