Snap.com will today announce the launch of its Snap Shots Ad Network. You may recall that Snap offers the link mouse-over pop-ups–briefly tested by us last year–designed to show you the location of a link before you actually click on it.

There are a lot of announcements expected at today’s start of Ad:Tech, so let’s kick off with MySpace.

A post by French blog Zorgloob has raised a flurry of rumors about Google organic rankings being influenced by Google AdWords advertising.

Zorgloob posted screenshots from an internal Google tool that assigns scores and classifications to Google’s organic listings raising questions about the way the Google SERPs are determined.

A new social network isn’t Yahoo’s only announcement today.

You can now log-in to your Google Analytics account to start enabling the new Site Search feature for a site of yours.

Raise conversions by 55% you say? That’s what Marketing Sherpa says in the promo copy for their new Landing Page Handbook.

Peter Kafka at Silicon Alley Insider and Erick Schonfeld at TechCrunch are reporting that Facebook board member and investor Jim Breyer said at an event last night that the social-networking site is open to working with Google’s OpenSocial project. The money quote:

If you’d like to make it easier for people to contact you via your blog (or MySpace or whereever you can post code), Windows Live Messenger has a site where you can create a nice-looking button in seconds that will get them in touch with your Live Messenger screen name.

Ionut Alex found evidence in the source code for the newest version of Gmail that hints at features we may be receiving soon.

He found code for Jabber transports, which would allow contacting people from other instant messaging networks over Google Talk/Chat’s Jabber connection, which makes sense given the fact that Gmail’s new contact manager asks for Yahoo, MSN and AIM usernames now.

Meta Tags were once a major player in SEO. With the advancement of search engine algorithms, meta tags become less and less significant. The description meta tag is still used for your search engine snippets, but the keywords meta tag has been disregarded by all the major search engines.

As several people are reporting this morning, the search engine Hakia has added a new feature called “Meet Others,” in which you can see whether other people using the tool are searching for the same things you are.

I confess that, like Richard MacManus at Read/Write Web, I am wondering what the point of this feature is exactly. Do social networking features make any sense as part of a search tool?

If you’ve been waiting for Google to launch its own computer and operating system, that day is here.
