Ever heard that Google loves regularly updated content? As a result of this you probably integrated a blog to your site and updated it daily with useless posts solely aimed at increasing your websites position in SERPS.
If you are doing this, you are effectively creating a content farm, full of useless content. You are just leaving yourself vulnerable to be penalized by Google.
If you want to spend more time updating your site, you should concentrate on writing quality posts that adds value to your website or blog. Each post should be unique and well written. The better you write your post, the more people will link to it. It is definitely better to write one post and get 100 links, than to write 100 posts and only get 1 link. Content is king and quality is queen, both go hand in hand to give you top rankings and returning readers.

Let your content reflect your site
The quality of your content reflects the quality and authority of your website in Google’s eyes. Google’s Amit Singhal quoted that “improving lower quality pages or merging them with higher quality pages could improve the higher quality pages ranking”, so in other words if you have low quality pages, it could be having a detrimental effect on your whole websites rankings in SERPS.
What you should do
You should be pro-active in writing your blog posts. Before you choose something to write about, you should go through each of your existing posts and ensure that you have not written about this topic before. If you have and you don’t feel that the post is up to scratch, delete it and completely start it from scratch, or you could add useful bits into your new post. This is definitely a good idea for webmasters to improve their rankings; go through each of your posts, remove ones with duplicate topics or collate them into new, more useful, higher quality posts. It doesn’t matter if it reduces the amount of pages on your website. Quality beats quantity all the time with SEO.
Rand wrote a good blog on who the winners and losers are from the panda update by having a quick read of this, you will notice that sites with potential lower quality content (such as article sites), have been affected really negatively by the Google Panda Update.
Good ways to find bad content
Google analytics is a great place to start when looking for content that isn’t performing. As Google has access to all this information, it is not impossible that it doesn’t use it as a ranking factor.
Make a list of pages with high bounce rates and low amounts of time spent on them. Then go through these pages to determine which ones you should consider deleting or improving the quality of. Once you have improved the quality, you should keep track of how the bounce rate differs and keep looking to better the quality of content on each page of your website.
Conclusion
The Panda update will hopefully have a very positive effect on the amount of good quality content on the web and reduce the amount of low quality content, content scrapers and low authority websites who get rankings in Google.
