After nearly a month after the introduction of Google refresh of the Panda algorithm and the introduction of a new one, later dubbed Penguin, trying to make a comparison of the two is tough because they were introduced almost simultaneously. When a site gets hit hard by algorithm changes what one sees and what one understands can be different. Algorithms can be constructed out of different conditions with rules, rules about rules, and rules to trigger those conditions which, depending on the complexity, might need to be governed by other sets of rules to prevent conflicts with the entire structure that determines the desired search results. Some of the recent changes that were glaring and humorous are "tells" to other conditions in the updates and even separates them visually because they are always related.

There are several ways to look at it but the title of your page should be easy to read and plain about it's contents. In the same way marketers attract people's attention, a good title can stand out in search results and benefit the user by finding your content. A question answered in a Matt Cutts video short at Google Webmaster Help, a webmaster asks about the differences, if any, between pipes and dashes in the page title.

Although there are recommendations from Matt Cutts on the use of dashes or underscores in urls, there is a difference and it applies to specific types of information due to an original language design. At the moment it appears that hyphens dominate the addresses for pages but with the use of underscores it would seem that users would react positively to the visibility. Let's find out and see the video.

With "Ads Choices", Google provides several tools for web users to opt out of interest and demographic advertising, view/add/remove the categories currently focused on them and even see details in the cookie used for tracking. On the other side of the coin, ad testing confirms mouseovers are being tested with ad units, but seem very limited. According to the official AdSense blog, the familiar "Ads by Google" will soon be replaced with a new "AdChoices" notice, label and icon which, when clicked, will take users to a page that explains the ads, online advertising and provides a link to the new options page.
