I am still relatively "new" to SEO and have a question about information architecture.
Currently, one of the websites I manage has over 1,100 pages of content. We were hit by Panda, but have since recovered our traffic and then some.
In the current structure, our content is accessible in the top navigation, via a drop-down menu with links to the top 5 content areas, and then a link to a general topics area that lists all of the topics not included in the above 5. In other words, it's two clicks to the deepest content in the site.
There is a plan to move access to the content out of the top navigation and into the super nav, with a mega drop down menu linking out to all of the different topic areas.
The top 5 topic areas will receive new pages that will contain 5-7 links of content (amongst links to other areas of the site), with a link to "see all articles" to get to the rest of that content.
This turns two clicks into three.
There will also be consolidation of some content, so URL's will be changing to accommodate this.
Aside from changing URL's, will moving the navigation of the articles, and pushing some of the best content down one layer have a negative impact on SEO?
My inclination is of course it will (I just don't know to what extent). But not having a lot of experience in this arena, some insight would be helpful.
