Search Engine Forums, SEO Forum

I have work on a review site, in nearly 5 days I notice my site has jumped up and down several times between about 15 and 150 positions. Even more than 3-4 times per day
And the best part is that the site that I don't SEO jump to the first page with the keyword I'm trying to rank with, and my site that I'm wanna SEO is missing.
I have made some websites but this is the first case I met, there is no error in the webmaster so I do not know how to fix, do you have any ideas?

hello i think that we have not to be afraid about google we need just teste all thing

Do not be afraid, work with Google for another ten years and cease to pay attention to such incidents at all.
