 Using the Google AdWords Free Keyword Suggestion Tool for Search Engine Optimization Research: Picking Keyword Phrases and Latent Semantic Indexing
There are numerous free keyword suggestion tools available to web
content writers for Search Engine Optimization (SEO) research. Popular
keyword search volume trackers include Google AdWords, WordTracker,
Overture, Self SEO, Keyword Discovery, and Submit Express. Among all
the keyword selectors, the
Google AdWords free keyword suggestion tool
stands out as
the most comprehensive and helpful for SEO keyword analysis and
boosting content's Latent Semantic Indexing (LSI).
The era of the individual keyword has long since come to an end. If
you're not thinking in focused keyword phrases of at least three or
four words, your content is likely doomed to remain undiscoverable via
search before you write a single word.
One of the main benefits of using the Google AdWords free keyword
suggestion tool is its ability to offer an intuitive variety of
synonymous and related phrases for any keyword phrase you enter. Using
some of the same technology that made Google the decisive winner among
search engines, the Google Adwords keyword tool provides the best
results of any keyword selector in this respect. By perusing your
results, you'll often find better options for your primary keyword
phrase that hadn't occurred to you, as well as potential choices for
secondary and tertiary keyword phrases and "long tail" terms.
With all these options, how do you go about picking your keyword
phrases using the data provided by the Google AdWords keyword
suggestion tool? The first consideration is search volume - how many
searches are done for a given phrase each month.
The Google AdWords free keyword suggestion tool shows both the previous
month's average keyword search volume and the average monthly search
volume over the course of a year by default. For more detailed
analysis, you can use the drop-down menu with the header "Choose
columns to display," located above the results, on the right side of
the screen. Included in the menu is the option to "Show search volume
trends," which opens a results column that graphs the year's search
volume by month. You can also select "Show highest volume occurred in"
from the menu, which provides a column identifying which month the
keyword phrases were most frequently searched.
The next step is to evaluate the existing competition for your possible
keyword phrases. High search volume often corresponds to a lot of
competition. However, if your keyword phrase is several words long and
tightly focused, the competition should be less daunting.
Many people new to SEO simply perform a Google search of their keyword
phrase to see how much competition exists. Doing this will provide
every indexed web page using the entered words. An optimized Google
search (enclosing the phrase in quotation marks) will return somewhat
better results, as it will only show web pages containing the exact
phrase as entered.
However, either way, a standard Google search is misleading. Search
engine ranking algorithms give significant weight to content titles.
Presuming your web content's title will contain your main keyword
phrase (as it should), the most important determination is how much
competition exists not with your phrase just anywhere, but with your
phrase in the title tag.
To find this information, preface the search on your keyword phrase
with allintitle:, with a space after the colon. This will return only
those indexed pages using the phrase in the title. This will generally
return a fraction of the results as a standard search.
Compare the potential keyword phrases from the Google AdWords free
keyword suggestion tool to the amount of competition using the phrase
in the title. You'll often find that some phrases with less search
volume than others have far less title competition. This makes the
less-searched keyword phrases a better pick for your Search Engine
Optimization. The choice between 500 people a month actually finding
your content or 5,000 people a month not finding your content should be
an easy one.
Another increasingly important benefit to using the Google AdWords free
keyword suggestion tool is its ability to help with Latent Semantic
Indexing. To put it simply, LSI, a crucial part of search engine
ranking algorithms, examines what related terminology appears around
keywords to make an accurate determination as to what the content is
about. Just as a human reader can figure out the meaning of words by
considering their context, search engines can cope with polysemy in a
similar manner.
For example, content with a high occurrence of the word "crane" could
be about a bird or a piece of construction machinery. By noting use of
words like construction, building, operator, concrete, pipes, lifting,
tower, mounted, etc., a search engine figures out that the writing is
about the latter.
Similarly, search engine ranking in part depends upon content being
obviously relevant to its keywords by use of related words and phrases
(meaning those commonly used in searches with some of the words you
entered). The Google AdWords free keyword suggestion tool provides in
its results a section entitled, "Addition Keywords to Consider." These
give insight into what terms and phrases Google (and other search
engines) consider to be relevant to the keyword phrase you entered. By
employing as many of them as possible throughout your web content, you
help search engines decide that the writing is indeed a good result to
show searchers when they enter your main keyword phrase.
Read the opening paragraph of this article again. The fact that several
of the most popular keyword selection and analysis tools are mentioned
is not just an instance of name-dropping. The Google AdWords keyword
suggestion tool showed that the names of these tools are associated
with the keyword phrase "keyword suggestion tool," as well as many
variations on that phrase. Hence, their inclusion helps to satisfy the
Latent Semantic Indexing aspects of this piece's ranking.
This covers the basics in how to best use the Google AdWords free
keyword suggestion tool for Search Engine Optimization research. It
facilitates picking the right keyword phrase for SEO campaigns and
optimized web content writing. In addition, making use of the related
words and phrases for LSI is now an essential part of SEO. Latent
Semantic Indexing is becoming increasingly important in search engine
algorithms, and it has already completely overshadowed the
ever-dwindling weight of keyword density. One of the most appealing
consequences is the ability to reduce the repetition that made
effective web content so tedious to both read and write. The freedom to
use synonyms and related terms improves the quality of web content, and
with the Google AdWords free keyword suggestion tool, you can be sure
you're incorporating just the right ones.
