Welcome to the Q&A Forum

Hi Chris, Correct me if this information is outdated, but Open Site Explorer sees no inbound links pointing to the site. Ahrefs (a similar tool) sees <a>two</a>. Along with David's points about on-site optimisation, this is a big problem - even with all the changes Google has made in the past couple of years regarding site quality, links are still a very important part of the ranking algorithm. It's very hard to rank well without quality inbound links from third party websites. I would look seriously into link development - the link building section of this blog is a great resource for ideas and current practices.

I have seen any changes in rankings related with penguin 2.0

Absolutely, would love their insight too. It certainly has me stumped as to why it has happened and I've only give a few potential causes, nothing definite. So would love to see as well!

Hi guys! So sorry about this, it looks like it is related to our latest index update that went out today. Our engineers are looking into it right now to get it fixed. We'll report back wen it's updated. Thanks!
