It really has nothing to do with "
How Many Phrases you Target", but for the record you should target at a minimum (3-5 Main Keyword Phrases per Page).
Everyone has access to Keyword Discovery tools or software that will produce a list of "keyword Phrases"--Most have no idea what to do with the data once they have it or how to locate the "Low Hanging Fruit" that converts. Most refer to this as the "Long Tail" but honestly have no real idea what this means.
In reality the only way to know for sure what keyword phrases convert to sales is to run a PPC campaign. Whole complete different complex subject:
Most will target the "Highest Traffic Keywords" they can find and think they have found the "Holy Grail" and will be rich in 30 days.
Well as they spend days and months, building content, submitting articles, writing blogs, building links, blah, blah blah, blah, they still cant seem to locate thier site anywhere on the search engine results page.
Then for a lucky few that hang in thier, after months and months their web page shows up for this high traffic phrase. They are impressed, they show their Family and even run and show their neighbors and friends of their success.
Problem -- High Traffic-- Broad Terms--High Competition-Low -No Sales
They may get a few leads, but nothing is really converting, just traffic, surfers, no intent. They just cant figure out why?
Stats: 85% of searches are informational only. 15 % are of commercial intent.
The best advice I can give anyone is this, Unless you study this and do this for a living nowdays,
(Not meaning reading some blog or some SEO forum of the greatest and latest technique).
Do yourself a favor and just hire a professional that understands how to optimize and market your site to produce relevant buying customers on a daily-monthly basis, this is not a guessing game anymore like it used to be.
I get to meet so many interesting people everday that are realizing how important it is to be able to bring relevant traffic to thier websites, no matter what the market.
I was just contacted last night from one of the owners of the
"World Hunting Group" and the TV Show
Relentless Pursuit. This should be fun! Not a Hunter, used to shoot a weapon, just didnt hunt animals, well human ones! but I get it.
