For the latest Google Panda update, I think Google just rebooted their system. And with the system reboot, I think decade old sites gets the boost. In fact, most of them are now on the top pages in every searches. Even hacked sites are hitting the higher pages.
So what does this tells us? In my personal assessment, Google just wanted to level the playing field. They’ve revived the old sites for us also to clean our sites. After a few months, we’ll be back again with the old practice i.e gaming Google.
Now since old sites ranked higher, I think it’s high time to give emphasis more with age rather than PageRank. I know age really matters but not just age anymore but rather how simple and ordinary you optimized your site. As what Google has mentioned,
“We want people doing white hat search engine optimization (or even no search engine optimization at all) to be free to focus on creating amazing, compelling web sites. As always, we’ll keep our ears open for feedback on ways to iterate and improve our ranking algorithms toward that goal.”
I guess it’s high time to call SQL Injection SEO Injection to gain link juice from those old sites!
