Keyword Rich Content

Implement as many keywords as you can into your content.
Crawlers search content as well, and the more popular
keywords you can work in, the better. Remember that you
are going to have a better CTR for AdSense if you have
more visitors. To have more visitors, you must have quality,
optimized content in order to gain, then maintain a good
search engine ranking.

Keywords:

Meta Tag keywords are placed in the header of your
webpages and represent the content of that page using
single words or brief phrases. The words or phrases used
are ones search engine crawlers will pick up when they index
your site and also the ones someone using a search engine
might type in to find your site.
It’s obvious to say that you should use Meta tag keywords
that are relevant to your site’s content. Don’t add any
keywords that have nothing to do with your site. Crawlers
may be essentially robots, but they do surf content as well,
and you can be banned from search engines.
List your products or services, any other applicable terms,
and even well known competitors if you want. It’s important
to have good keywords (or key phrases). There is software
out there that helps you pick keywords and allows you to
maximize your keywords so that the ones you use are theones most frequently used by search engines, just research
before you buy.

Keyword Generators:

The best way to select keywords is to choose ones that are
already searched for frequently. There's no need to pay for
a keyword generator unless you want to. Overture will give
you the top 25 keywords that were typed into search
engines for the previous month. Just enter a term related to
your page. Bookmark this site for whenever you create a

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.

Robot Tags:

Robot tags let you specify what pages on your site are
indexed. Robot tags go in your header, but you can also
create a text file. The text file will be the first thing they
“read” when they’re on your site. By using the text file, you
can specify which pages not to index and insure only the
content you want in the search engines will appear. To
