Why do I always get Google dance when I post 3-4 new (original articles in 1 day)?

I have a few websites, and yesterday again after I put 4 new articles that I let somebody write for me (100% original), I get Google dance again. The site I updated yesterday was #15 on a very high competition KW (0.99 (= 99%) competition in G-KW tool), today I could not find it in top 50.


Last time my site was dancing and after 2 weeks I gained 2 spots, another time it just jumped on place in SERP. Usually after an update it dances for 1-2 weeks afterwards I gain a few spots. No linkbuilding, only adding good quality content every time....

Does anybody else also have this problem happening to their sites?

I really do not understand this? Can somebody explain this?

It's normal , especially for new sites but not only.
If your main page would link to this new article and this article is having a good title and a good keyword density for what you are ranking already then when google will index your article will see it's relevance for a keyword and place the article somewhere in the SERP.

A few tips :
1. Make the new article based on other secondary keywords and not on the ones you are already ranking good.
2. On the new article post a link to your ranking page (usually the homepage) with the keyword in anchor text

I usually blast the new added articles with 30 profiles , some social bookmarks and some web 2.0 , in this way all the link juice you will get to the new article will transfer to your main ranking page (if you add a few links with keyword anchor text from the new article to the ranking page, see second tip)

The effect of google dance usually appears when google index a lot of relevant pages for a keyword , that's why you also get in a google dance when you just make in 1 week 500 web 2.0(or 20 000 profiles) related to the keyword you want to rank for. After google sees that all this new pages in his index point to a specific page will rank better that page(from my experiments this happen after 2-3 days after the indexation )

Here's a quick and simple tip, submit the posts inside WP, but only publish one right away. Set the other 3 to be published one day after each other. That way you won't get a "massive" influx of content at once and G will treat your site as more stable.

Yeah, today sites are back, but strangely have lost positions.

the one on #15 is now #17 and the one on #10 is now #12

Strange.... These sites were 5-10 post sites with with Google translate translated articles half a year ago, I used to do this, just to index the sites and when they were in the top 30, I would invest time and money to make it decent, now it dropped
