Search Engine Optimisation Trends

"What's the hottest trend in search-engine optimization that you've never heard of (yet)?"
It's LDA -  Latent Dirichlet Allocation (LDA)—a context-based algorithm for determining search relevance. According to SEO research, on-page content may play more of a role in your rankings than previously thought.
That's because the LDA algorithm (which Google will be using ) "looks at the total picture of the content and its context,". A Web page about World of Warcraft, for example, needs to mention "paladins, death knights and fish feasts" to rank well with LDA.
So, how do you act on this knowledge? Here are three ways to optimize on-page content for LDA's critical gaze:
Use the rel=canonical tag on all your original content. As contextual content becomes more important to search engines, the temptation to use someone else's content,  will be much greater. To assign some level of ownership to your content, we advise applying the rel=canonical tag to your site pages.
Stay on topic. Your website content "needs to have lots of original, high-quality, on-topic content using semantically related words … that correlate to the search terms you're going after". You must "do the hard work of creating good stuff in order to leverage this algorithm effectively,"
Stop giving away so much. Don't give away the keys to the kingdom—your fab content—to social-media sites. Though it's fine to share excerpts, draw the line at giving away large chunks of context-rich copy to sites you don't control.
The Point: Time will tell whether LDA is an SEO game-changer. In the meantime, you'll never go wrong creating lots of original, standout content on your site—and protecting it.
