Latest Google Tool - Google Ad Planner

Google Ad Planner, a research and media planning tool that connects advertisers and publishers. When using Google Ad Planner, simply enter demographics and sites associated with your target audience, and the tool will return information about sites (both on and off the Google content network) that your audience is likely to visit. You can drill down further to get more detail like demographics and related searches for a particular site, or you can get aggregate statistics for the sites you've added to your media plan.

Best Internal Architecture for SEO

Internal linking should also be done with the help of in-text link rather than navigation menu.

What’s the difference ?

Navigation Menu	In-Content Links
Consists of sitewide isolated links that carry less SEO weight.	Are links in context that allows search engines to learn more about the destination page.
Offers more control over website internal structure: you don’t need to think much of internal interlinking once you set up your navigation.	Are more spontaneous (more difficult to manage) but offer full control over internal anchor text.

To my mind, in-content links are not going to replace navigation menu completely (after all, there is nothing better from usability point of view and it can be easily and thus effectively managed). The point of this post is to encourage webmasters to experiment moving some of your links from the navigation menu into the content area and also to try the following:

* breadcrumbs;
* “related categories” and “related articles” blocks;
* different navigation menu for different page types; etc.
