If you have spent any time researching SEO or PPC you have probably come across the phrases “head terms” and “tail terms.”
In order to understand what this means imagine a graph that starts really high on the left, but falls steeply toward 0 as you go to the right. Imagine, however, that the graph just approaches 0, but never reaches it, for miles (yes, that’s a long piece of paper).
This is a pretty accurate depiction of search engine queries every month - there are a few really high-traffic keywords (iraq, plasma tv, etc.) and then an astoundingly high number of keywords (more specifically, phrases) which may only receive one search per month (”where can i find news about the war in iraq,” “plasma tv 32″ wall-mounted,” etc.)
Five years ago when I started getting involved with SEO everybody wanted to own the head - meaning they wanted to rank well on the high-traffic terms. It’s pretty easy to figure out why - without as much competition as you face today they were easy to own and would result in a ton of traffic.
In the past couple years, however, I have seen more people focus on the tail. There is a lot to like about targeted queries such as the ones that have low search volume - while the volume of searches per query is very low, often there are several similar queries which produce an impressive aggregated volume.
I think, however, that the importance of the tail terms may have been overemphasized in the past few years and we strongly recommend that you consider your business model before making a decision - and don’t be fooled, this is an important decision to make before even choosing an SEO. Some are much better at getting head terms while others focus on the tail.
Do a bit of research and as your potential SEO what they recommend - make sure to talk to a few companies and ask for specific referrals for both head and tail keywords. Figure out what you need in an SEO and then seek out the best overall fit.
