Google is dancing latino?
I have some experience in SEO and internet marketing, but some things i have seen these days are too strange to understand.
From the beginning i want to tell that i am not doing: link building campaigns, link buy, link exchanges, copy articles from other websites or anything that might violate the webmaster guidelines made by Google.
What i do: i regularly update my content with new articles made by me (not copies) and i participate on discussions on some blogs or forums where i have interest. And that’s all.
This month happened to 2 websites of mine a strange problem. 2 times this month i have been on top 10 for some good keywords, and yes 2 times google pushed me back. Every time after 2 weeks the websites were back on the good road.
From my experience this happens when, you lost links, you copy content, or violate some Google tos. Well i didn’t done anything from this.
If there is anyone able to tell me what’s going one maybe i am able to pay him.
