Meta data is information used to describe the document but it is not displayed. Two common types of meta tags are keywords and description.
Keywords and Meta Data
Keywords make it easier for search engines to find your page. You can put words that describe your page within a meta tag. Open a bracket, type meta then a space. Type name= keywords in quotes. Then type content= quote, and now type some keywords that describe your site. Separate them by commas. Don't forget to close the quotes and brackets.
Meta Data Descriptions
Description is a short synopsis of what your page is about. Mainly, it's used for search engines so they can describe to the viewer what is on your webpage. Start with a meta tag, only in this one, instead of keywords type 'description' in quotes. Then content= quote and type your sentence. Don't forget to close the quotes and the bracket.
Meta Tags and Sourcing
You can also use meta tags for information such as author and copyright information like this:
U.S. Internet ad spending in the fourth quarter of 2007 grew nearly 28 percent over the same quarter in 2006 to $7.3 billion, said analyst firm IDC.
For the entire year 2007, online ad revenue grew 27 percent year over year to $25.5 billion.
IDC said that Google's net U.S. market share dropped for the first time in two years because of a slow down in growth in domestic fourth quarter sales. Google's net U.S. advertising market share decreased 0.5 percentage points to 23.7 percent last quarter compared to 3Q07.
The estimated net U.S. Internet advertising sales for Google (excluding the traffic acquisition costs they pay out to the partners in their networks) grew by just over 40 percent in 4Q07, but its year-on-year growth rate in the quarter before had been 50 percent.
"If a merger between Microsoft's new media business and Yahoo! would come to pass, the combined entity would have a net U.S. advertising market share of about 17% based on our 4Q07 data," says Karsten Weide, program director for IDC's Digital Marketplace: Media and Entertainment service.
"It would not quite bring Microsoft-Yahoo! to where Google is in online advertising in the U. S., but it would give them a much better fighting chance than if they went it alone."
As with pretty much every tweak made to the social network, we're not sure this will get much attention in the U.S. People in other countries may be interested, however, as starting this month, social applications will become available to Orkut users.
Want to get one of your own in front of their eyes? Better act fast - submissions for completed applications are due by February 15th. And as that's a short deadline that clashes with Valentine's Day, we'll once again note that OpenSocial developers courting American audiences may not stand to gain much.Google Preparing To Put Applications On Orkut
Also, we're not too sure what sort of apps Google will allow on Orkut, or how users will respond as a result. The social network's official blog has frequently made pleas to "keep Orkut beautiful," and zombies and tossed sheep have tended to have the opposite effect on Facebook.
Still, developers with a wider target than America in mind could benefit quite a bit, since Google's apparently counting on growth to occur as a result of the applications. On the Official Google Blog, Amar Gandhi stated, "We'll start ramping up to more than 50 million people over the next few weeks."
So some dates may get cancelled after all. And on one last time-related note: we'll bring updates if and when Google gets more specific about the applications' availability.
Users of social networks are spending less time on sites like Facebook and MySpace and it could be due to the number of ads.
The average amount of time spent by users on social networking sites decreased by 14 percent over the past four months according to comScore. MySpace has seen its users dip from 72 million in October to 68.9 million in December, comScore says. The total number of users is still growing at an 11.5 percent rate, but that's a decrease from past growth rates.
"What you have with social networks is the most over hyped scenario in online advertising," Tim Vandehook CEO of Specific Media told BusinessWeek. Still advertising on social networks is rapidly growing. Last year ad spending worldwide on these sites increased 155 percent, to $1.2 billion, according to eMarketer. This year, eMarketer predicts it to increase 75 percent, to $2.1 billion.
Social networks have low response rates, advertisers and ad placement companies say. Marketers say as little as 4 in 10,000 users who see their ads on social networking sites click on them, compared to 20 in 10,000 across the Web.
Google, which has a $900 million ad deal with MySpace, said it did not bring in as much revenue from the agreement as expected. "I don't think we have the killer, best way to advertise and monetize social networks yet," said Google co-founder Sergey Brin.
News Corp said its revenues for Fox Interactive Media were up 87 percent to $233 million, but $62 million came from Google's guaranteed ad deal with MySpace. Analysts say that Google is losing money on the deal.
On the Google, MySpace ad deal Donna Bogatin writes," MySpace has its direct hands on the 'good' MySpace ads goods, while Google is an outside ad serving player, playing around with runnerup inventory."
