Robots do not think. They need structure. There are several areas you can control that will have a significant effect on how Search Engines index your site. First 200 characters of your text. The title of your page website.
Content is king.
In the long run, the robots are smart enough to know when you really have content. Example, one site owner in the dog grooming business spent a lot of time to create a page to advertise his service. Then he could create a page for each breed of dog. Each with its own unique set of keywords.
