In the past month, we have seen the launch of Panda 4.0 and Payday Loans 2.0. There is also a lot of anticipation for the Penguin 3.0 update. I’m predicting that Penguin 3.0 is launched around SMX Advanced 2014. Matt Cutts always has something up his sleeve for SMX Advanced. Penguin 3.0 would certainly be the talk of the town if it happened next week. Do it, Matt!

In addition to the algo/filter updates, there was one news item that kind of slipped under the radar: “Understanding web pages better

Google is the javascript executioner

The line that made my jaw drop was:

“In order to solve this problem, we decided to try to understand pages by executing JavaScript. It’s hard to do that at the scale of the current web, but we decided that it’s worth it.”

In the past, Google appeared to execute javascript for sites where they deemed it absolutely necessary. Today, Google is executing javascript for ALL THE SITES!



While everyone is talking about Panda 4.0, which isn’t going to affect many big brand retail sites, this javascript news has the potential to affect everyone.

You know that one client who has their entire navigation built with javascript? Or what about that client with the product details built with javascript? Or what about that client who uses so much javascript that it slows down the site and you’ve always been happy that Google *DIDN’T* execute their javascript? Yep. This news is big news for SEO, and it will likely impact all sites.

If anything, this is another indication that Developers and SEOs will need to work together for the common goal of creating sites that work well and rank well.
