I registered my site a little over a month ago and it was slowly picking up in rankings. I did a decent amount of link buliding and as I build links my rankings for those keywords went higher and higher. Then I added an extra paragraph on one page of my site along with building about 6-12 more links. The following day my rankings vanished. I went from getting 200-300 uniques from google a day for this site to 0-2. Did I get sandboxed?
Ouch, reminds me of an experience I had too. I had a review page for water4gas products that was miraculously on the first page of the google search, and then stupidly I changed a paragraph to make it seem more "seo friendly" and then BAM, off google search completely. At least you learned a valuable lesson!
Yes you are now in the sandbox. Next time make changes more slowly so that it appears natural (but even this doesn't always help)
So what can I do to get out of it? Will removing the paragraph help? How much more slowly do I make changes, site was up 2 weeks later I put up another paragraph and in between I added links. Would removing the paragraph help fix rankings or it's best to leave the site alone?
i find you can get sandboxed for more or less anything. most of the time its just because your a brand new site more than anything. i would just carry on building links and adding content as you would ifd nothing had happened. also petition for reinclusion on google webmaster tools.
get more links as well, if you have a lot of links pointing to your site, it makes your site hmm more "trusted". It can help you get out of that deadly box
