Econsultancy Site Migration and SEO Impact – the story so far

Site Migration and SEO impactOn 14 December 2008
we relaunched the site. This involved a subtle name change (“E-consultancy”
became “Econsultancy”), a new logo, a completely new look site with a new
directory structure, a new URL, on servers in a different country. We had to
migrate 10,000s of pages, deleted a load of old ones, and created 10,000s of
new ones.

The background to all this is explained in my interview
about the new Econsultancy site
– and question 9, about the SEO impact of
this large change, is the subject of this post. What has happened to our
previously excellent search rankings since the changeover?
