Every time Google has an algorithm update, some people lose rankings, and others jump up.
Most times you will only hear from the people who lost rankings.
For the sites that I work with, some clients are always wanting to know the next thing to do.
In Search, there is always something that can be done – links, content creation, technical issues, etc.
But sometimes the best approach is to do nothing.
Yup – SEO’s dirty little secret.
Just like anytime WordPress updates it’s software, there is almost always something that got overlooked. It’s not that the people working on the product missed it, instead, it was more likely an affect that wasn’t anticipated.
Just as Google recently MISTAKENLY penalized sites that had parked domains pointing to them, this just shows that even really smart people can sometimes make a mistake.
This is why when every update comes out, you should wait a few days to then adjust your strategy.
