Descriptions

Meta tag site descriptions are not read by Google crawlers
because they generate their own descriptions for the page,
but other search engines still use them. The best way to
come up with your site description is to use the first one or
two sentences of text on the page. It’s worth your time to
use this tag because it gives you some control with various
crawlers.

Geo Targeting
If you offer a product or service to a certain city or
geographical area, you can specify that in your keywords
and description. Doing this may be very crucial in drawing
in targeted traffic from search engines. However, avoid just
naming small areas because that limits the customers that
can find you. If you’re a northern California chiropractor,
don’t just list the county or city your business is in. Always
aim for the larger audience to get the maximum results from
search engines.
