Firstly, we are a small entrepreneurial team of 3 persons and I am more like an amateur webmaster of the company's website as we cannot really afford a technical guy/department right now.
A few weeks earlier, our website traffic and rankings for most keywords decreased overnight. I did a lot of reading henceforth and learned about Penguin 2.1 which people said is the reason for the drop. Something like this had never happened before. Now, I have gone through the entire Google webmaster help section. It says there that if a manual penalty is taken against us, we would notice a message in Manual Actions page. So far, we haven't received any notice from Google for web spam.
Some SEO guys I contacted said they found spam links in our backlink profile. I do believe I had mistakenly purchased a cheap link/SEO scheme when I was yet very new to SEO. This was more than a year back but since then we have been legitimate. Moreover, how do I find out which is a spam link and which is not? Our content is all original, refreshing and the best you will find in our niche. We also have a blog but on a different domain (wordpress.com) from where we send out anchored links to our business website. Is this a good thing to do?
Now, how should we proceed and recover our traffic/rankings. I tried searching in webmasters for a way to reach google and ask them why the traffic has decreased suddenly, but I couldn't find a contact form or something.
Can someone please help in making things more clear regarding the reason for the drop, along with a solution. Our website is [snip]
Will really appreciate this as I can't get to figure this out and its taking a lot of time.
