Please also see What does an SEO Agency Do as that will also answer this.

A good SEO agency will largely eliminate the random and bring focussed order to your online content.

To do this a good SEO agency has to get you involved. it can’t be done without you.

A good SEO agency will also..

  • .. focus your online messaging and brand regardless of the size of your business.
  • .. not bamboozle you with 50+ pages of stats, graphs and terminology. It shouldn’t be about them.
  • .. give you realistic goals.  There is little point in implementing an SEO strategy when there are no resources available to physically do the work.
