The 3 Types Of Keyword Database

If you have been marketing on the internet for a while now, you should have
realize the importance of keyword research. It doesn't matter how or which
way you earn money online, most likely or not, you still must have the

assuming keywords you think people are searching in the search engines which
may not be true.

Most people uses overture keyword inventory database to find out what people

Comparing the 3 keyword database

Let's take a look at how all 3 keyword database gather their database of
keywords.

For overture, it is the collective keywords gathered by the yahoo and
overture search engine and it tracks keywords up to 30 days.

One disadvantage of overture is the keyword search volume may not be always
accurate as it can be skewed by automated bots hitting their search engines.

For wordtracker, it uses meta search engines such dogpile and metacrawler to
gather its keyword database. It tracks keywords up to 90 days and it's
keyword database has approximately 330 million keywords.

Wordtracker database is more accurate than overture as the chances of
automated bots hitting meta search engines are pretty remote.

The disadvantage of wordtracker is that it does not accurate represent the
internet's search volume keywords since meta search engines only takes up
less than 1% of total keyword search volume.

For keyword discovery, it gathers data from more than 180 search engines
with the majority from google. It tracks up to
365 days and has approximately 32 billion keywords in its database.

The major advantage of keyword discovery is in its massive keyword database
which can allow you to dig up keywords that may not show up on overture and
wordtracker.

Now you might think keyword discovery is the best keyword research tool
since it has the largest keyword database.
However it may not be necessary depending on what you want to do. For
example, if you are just trying to come up with new ideas for a product or a
website, then overture and wordtracker will be sufficient.

If you are trying to gather a large keyword list for your niche, then use
keyword discovery. If you are doing ppc with adwords or yahoo search
marketing, then developing a huge list of keywords is important and keyword
discovery can do that better than wordtracker or overture.
