I believe this about sums up the SEO’s encounter with the Panda.
Son: Dad can we get some more hits please?
Dad: No Google says we already have too much.
Google Panda: And just for asking… Bye-bye SEO shopping cart.
< Smashes the food on your table to oblivion >
Get in line… You never want to meet the Panda.
… Many SEOs and website owners aren’t laughing.
While I may jest about the Panda 2.2 roll out, many companies are struggling to keep afloat with Google’s new algorithm change. Desperately reaching for alternative methods to cope, like improper use of rel=canonical tags, to stop the blood flowing from their site’s life lines. When you put people in desperate situations you get panic and survival mode.
If you have seen the Kung Fu Panda 2.2 strike then you are not alone:

Before Panda you could do some cheap tricks that don’t work anymore. I had a fiverr xrumer blast at an avvo profile would get it into the top ten. Doesn’t work anymore:( Overally though it’s a step that needed to be accomplished but I’m not sure a manual penalty wouldn’t have worked better given the small number of offenders(ehow, ezine etc).
Google does their best… and in the end, it’s their search engine.
