We've talked about this before, and it recently came up again, after reading Hubspot's blog about asking other people for inspiration.  what to blog about. The long tail is a valuable resource for blogging, you can find unusual keyword phrases, perhaps a local variation that you haven't optimised for (like our SEO Portsmouth example).

Measuring the size (length?) of the long tail is also a good metric for working out the success of your SEO campaigns, it is one of the KPIs that we use in-house to monitor the progress of a campaign over time.

So if you look at your long tail results, you should find something that you can blog about. It doesn't matter if you use long tail keywords from a PPC report or an SEO one, either can be used as a source.

So here are a few interesting ones I have picked out of our long tail - I especially like the question ones as they create something that is answerable in the blog format.

What can I constantly do to improve search engine rankings?

What results should I expect from blogging?

Which is better SEO or PPC?

Why agency should partner with SEO company?

How to submit to Google Local?

How long does it take for page rank to transfer?

How many keywords are maximum for optimisation?

How to get top ranking on Live Search?

What is a SERP?

You'll also find a few real oddities, which will make you laugh if nothing else, and they can make fun blog topics in themselves. For instance someone has come to the Vertical Leap site recently looking for "yellow pages advert slogans" - not something you'll likely find on a search engine marketing blog!
