The trouble is, anything you do to try to gain favour with a search indexer:

a) Is going to distract from the quality of your content, unless you should be doing it anyway

b) Is going to be irrelevant (at best) or counter to your original intent (at worst) when the indexer's algorithm changes, and Google are changing their algorithm all the time, with far more resources behind it than you have to keep up with it.

You "A" point is why we've seen the rise of "content marketing" over the past few years.

Of course, that practice gets exploited a lot, with people using word mixers, automated article writing, low quality writing, etc. as a means to just fill up their websites.

However, there are lots of businesses that do content marketing in such a way that it benefits the company's search rankings, but also provides high value content to interested person. Since we're talking SEO, look at Moz. They sell premium tools to help companies improve their search rankings, but also offer a wealth of free, quality information to people interested in online marketing.
