Have you read the Google Blog?
Keeping up with the ever changing Search Engines is one of the key challenges that every SEO professional must endure. In the quest to have the most relevant search results and the largest market share every search engine is always tweaking their algorithms.
You can spend over 80 hours a week studying these algorithms or you can just read the Google Blog. Google does a great job at keeping the general public informed about the changes at Google. I recommend that you visit their blog at least once a week to read the latest changes. If that doesn’t convince you also consider that Google has put together a great list of personal blogs that they are reading.
Give it a try!
