The Google Dance!
Just as a heads up for you new to SEO, when you make changes on your website and do everything right, you share in socially, you fetch as Google the post you have just written, and then the next day you check your ranking and see that your site has tanked a page or two or even disappeared this is not the time to freak out.
Google does a thing called the google dance every now and then and if you just chill and give it a day or two, you may see your ranking come back not only where you were but higher.
I have had sites that produce good money completely disappear from google for a day ior two after adding content.
Just relax and like I said, give it a day or two,then if things are not better then start investigating.
Just thought I would share this in case any of you have or are experiencing similar results.
