Back in June I was ranking at the top of Google SERPs for most of the keywords on my website. My organic traffic was between 1,000 and 1,500 visitors per day on average. I have incredibly high quality natural backlinks from major media organizations. However, around the same time as the Google Penguin 2.0 algorithmic update in May/June I also changed my WordPress theme. This is when I started noticing a decrease in search traffic. Since then, my organic visitors have decreased to between 100 and 200 per day, a massive drop. I believe the problem may have something to do with HTML issues with my website that happened when I switched WordPress themes. The Penguin update shouldn?t have affected me because all of my backlinks are natural and not the spammy types that Google was targeting. Although, I am really not sure what the issue is. I need a diagnostic run on my website to check for any SEO and HTML problems that may be affecting my SERP rankings. I would then need the problems with my website fixed in order to reclaim my position in the Google search results. Any thoughts or suggestions either about what I can do myself or who I could contact for services would be greatly appreciated.
