Attached you'll find my April 2010 Top N Trends charts. There are an analysis of the Top 100 google results for a large number of high traffic searches ranging from online retail to entertainment and news. I use charts like these to test the limits of "SEO" factors and to detect if something may or may not be an SEO factor. I promise you'll love this data and it will raise more questions than it will answer, but it will answer some too. I will happily discuss individual charts in this thread and I hope to get new test ideas from you. About my SEO Lab: I have a VPS Linux server that I don't conduct business on. Its goal is to be a reputation buffer from my actual sites. I conduct all my SEO experiments on that server which I have dubbed the "SEO Lab". I only move SEO tactics to my real sites when they have proven successful in the lab and suffered no attention or ill will from Google and others. Never experiment on your real sites... its just not worth the risk. I use a grid of 6 "$5/month" PHP web hosting accounts as my anonymization network. They have PHP scripts for funneling google searches round robin. I delay 3 seconds but run 6 requests at a time so 0.5 seconds per 100 results. The grid ties into adwords API and AWS Alexa api and others for meta data. It is all queue based so I can feed a url or keyword into the queue and it becomes part of the "Machine" overall. I hope you appreciate what was involved in getting this data. It's my pride and joy.
