---- Trick to Google Ranks - Using Semantic Best Practices

PS: I should add to the above that I believe that Google is now using schema markup as a guide only, and is looking for confirmation on multiple other levels. Here's a thread where I relate the loss of rich snippets to other signals....
Over the years, I've described Google's index as a multi-dimensional model of user behavior and the web. I think that multiple indications of trust, authority, and user popularity are increasingly being considered to confirm all markup, all links, all content, etc. As Google gains confidence in its ability to make accurate discriminations, it will do so... and low quality sites which don't merit rich snippets are not going to get or retain them.
At this point, I believe that schema markup will make it easier for Google to understand your site, though I doubt that it will fool Google into thinking the site is "better" than it is. While the above discusses rich snippets, the principle applies to all kinds of uses that semantic markup might be used for. Chances are that some sites that are right on the fuzzy line may get a temporary boost in a particular area from schema markup, and they might then drop down.
Certain kinds of signals are likely going to be very hard for Google to parse without the markup. Ranking is probably the area where Google is most particular about requiring multiple signals. That said, I think that schema can be extremely helpful in ranking some types of content if the other signals are in place.
