⟩ Do you feel that information architecture (in this case I mean the categorization of web pages for find ability) can have an effect on site optimization? I suppose I'm asking if things like intuitive URLs and labels can reduce the need for extra context on a page. How would you separate site optimization and usability/IA?
Yes, there is a tradeoff for some techniques between IA and WSO, and with Search Engine Optimization (SEO). Good IA has a logical hierarchy and clear, unambiguous labels. Some WSO techniques uses short abbreviated names and URLs to achieve savings, which can preclude descriptive terms. SEO also can conflict with IA and WSO, with some sites sacrificing logical hierarchy to create keyword-filled directory and file names. Balancing these three disciplines is an art in itself. For high traffic pages like home pages, I favor speed over IA and SEO. In the book, I discuss mapping techniques that you can use to have the best of both worlds. The book gives you the tools you can use to optimize your content. How far you go is up to you.
