What is Keywords in SEO?

Generally Keywords are phrases under which you would want your website to be found in search engines.

Keywords are typically two-to-five-word phrases you expect people to search for to find your website.

Oftentimes, corporate climates force
people to refer to things using special phrases.

Keywords are not about what you
call your stuff. Keywords are what Joe average surfer (or your prospective site
visitors) may type in a search box.

Some Steps For Finding Best Keywords:

Focusing Keywords:

When people tell you to target the word free, they are out of their minds.

That single word is too general and has too much competition.

I just did a search on Yahoo! for free and it returned 749,000,000 results.

That is over 10% of the web trying to use free as a sales pitch.

I am not saying that free should not be on your page; it is a compelling offer on
many of mine.

I am saying that keywords should define the product or idea. Free alone just does not get this done.

Keyword Length :

A longer search phrase is typically associated with better targeting and increased consumer desire.

Some people say shorter keyword searchers are shoppers and longer keyword searchers are buyers.

As you add various relevant descriptive copy to pages, you are more likely to
appear in search results similar to your keywords that do not exactly match your
more generic root-term keywords.

Most good keyword phrases are generally two to five words.

Keyword Value Pyramid:

One of the most fatal flaws of many SEO campaigns is that people think they need
to rank well for one term or a few generic terms.

Generic terms may occasionally
convert, but most strong-converting search terms are specific.

If you read SEO forums you often hear many posts about something like a San
Diego real estate agent no longer ranking for a generic term such as real estate.

Since the term is too generic for most of his target market (and his service would
not be fitting for most people searching for that term), it makes sense that search
engines would not want to show his site in those search results.

As search continues to evolve, it will get better at filtering out untargeted or inappropriate sites.

Targeting generic terms outside of your area means that you need to use aggressive
techniques to try to rank. There are several problems that can go along with being
too aggressive:

• Targeting exceptionally generic terms may not add much value, since the leads are not strongly qualified. Paying extra to rank for more generic terms may not be a cost that is justified unless you can resell those leads at a profit. 

 • Being exceptionally aggressive raises.            your.risk profile and makes your site.            more likely to fluctuate in rankings when      new search algorithms are rolled out.

•  Some of the best value is at the bottom of      the keyword pyramid.

If you spend too much time focused too broadly on the top you may miss some of the exceptional value on the bottom.
