If you haven't read it already I thoroughly recommend you read the Q&A with Shari Thurow on the Library & Information Update blog. In the blog post Shari provides excellent definitions of Search Engine Optmization (SEO) and Information Architecture (IA) her definition of SEO is as follows:
- SEO is the abbreviation for search engine optimisation (or optimization). On the Web, search engine optimisation is commonly viewed as the process of optimising a website for people who use search engines.
Shari also provides a more detailed definition of IA, which I'm not going to reproduce here as you can read it on full on the blog post or on the Semantic Studios website
This is a concise blog post but I'm looking forward to Part 2!
