Hi, Having read all this advice I can see its going to be a busy weekend! After 'Panda' many sites have collapsed but I have found that Squidoo has surprised me as it seems to be keeping popularity and as mentioned above, makes a little money as well as helps driving traffic. Hmmm...50 ideas....shall I start from the top or be different and work my way up from the end of the list?
Google makes constant efforts to improve the search algorithm and detect quality content and that is why it rolled out the Google Panda 4.0 update.  What is this update really doing? It deranks low quality content and boosts the high quality one, according to Google’s idea of valuable content. In the screenshot below you can see what kind of content you shouldn’t be looking into if you are really determined in making a mess out of your organic traffic. 
Clean, fast code is important and you need to be aware of this if you’re using WordPress themes or other CMS platforms that typically come with a lot of bloated code. Despite its chunky build, one of the key benefits of using WordPress is its structure of templates that allow you to create new pages at the push of a button and create content in a visual interface, rather than code everything yourself.
So what does this mean? “Bounce rate” can be thought of as a measure of engagement. If visitors are moving around your site, they are engaged. If they are bouncing, they cannot think of a good reason to stay. There is one notable exception to this: Blogs, videos, and news sites often have higher bounce rates because a visitor reads a particular article or watches a video and then leaves. For an ecommerce site, however, you would like to see relative low bounce rates. Sources that bounce a lot are probably not providing quality traffic.
Beyond organic and direct traffic, you must understand the difference between all of your traffic sources and how traffic is classified. Most web analytics platforms, like Google Analytics, utilize an algorithm and flow chart based on the referring website or parameters set within the URL that determine the source of traffic. Here is a breakdown of all sources:
