When using tools for keyword research, it’s important to remember the differences between the keyword match types of Exact Match, Phrase Match and Broad Match, when determining search volumes and competition levels.
When you use the Google Adwords Keyword Tool, or the excellent Market Samurai keyword research product, you can get an indication of monthly or daily search volumes for a keyword term based on the three keyword match types as follows:
Keyword Match Types
Broad Match – indicates the number of searches made where all the words in the keyword term are present in the search query. They can be in any order, and may have any other words included.
For example: The number of broad match searches shown for ‘keywords research’ would include searches made for the terms ‘keywords research’, ‘research keywords’, ‘how to research keywords’, ‘keywords research tool’ etc…
Phrase Match – this indicates the number of searches made where all the words in the keyword term are present in the search query. Unlike broad match, they must be together and in the right order, although they can have other words before and after.
Using the same example above, the number of phrase match searches shown for ‘keywords research’ would include searches on ‘keywords research’ and ‘keywords research tool’ but not ‘research keywords’, ‘how to research keywords’.
Exact Match – indicates the number of searches made that only include the words shown and in the right order. This time, only searches specifically for ‘keywords research’ would be included in these results.
Notation for Keyword Match Types
The standard notation for the different match types is:
Exact Match uses [square brackets] around the search term – e.g. [keywords research]
Phrase Match uses “parentheses” around the search term – e.g. “keywords research”
Broad Match uses nothing around the search term – e.g. keywords research
Different Search Volumes by Match Type
For relatively short keyword search terms (e.g. 2-3 words), as shown in the image above, the total of all the searches made on the phrase match variations will be higher than those for just the exact match. The total number of searches on all the broad match variations will usually be higher still.
As the length of a keyword phrase increases, you may notice these differences reducing as the number of alternative options for broad and phrase matches variations of a phrase also reduces.
The “Phrase to Broad Ratio” or PBR, is the percentage of Phrase match searches out of Broad match services made for a keyword and is a useful indicator to the degree of focus a keyword has. A keyword with a high PBR suggests that most searches are made on close variations to the keyword, while a low PBR suggests a much wider variation in actual search terms involving the keyword.
Keyword Match Types and Keyword Research
Typically, as the length of a keyword phrase increases, so the number of searches made for it decreases. The flip side is that there are also likely to be fewer sites competing for the phrase.
Additionally longer tail keywords are also likely to have a higher PBR and so are likely to be more focused keywords. That is to say, people searching on them are more likely to be looking for the same information. For example, people searching on ‘blue extendable dog leads’ are searching for something very specific and more particular than just ‘dog leads’ or ‘lead’ or ‘dog’.
A page or post that is optimized around the the keyword ‘blue extendable dog leads’ is likely to be easier to rank for initially than ‘dog leads’.
As more content is added to a site over time, using other related keywords on additional pages and posts, the number of closely related keywords for which Google will rank the site grows. So a site will be generating more traffic based on “Phrase” match queries as well as [Exact] matches.
Again, as more pages and posts are added using more related keywords, and the site gains more authority, it will rank better for broader search terms based around the keyword selections and start generating more traffic from Broad match queries.
One way of thinking of this is that:
- [Exact] match is the short term traffic potential for the keyword
- “Phrase” match is the medium term traffic potential
- Broad match is the longer term traffic potential
Keyword research is vital to the success of a site.
