Articles for Webmasters     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.
