Google Image Search Text Ads assumes the reins of goverment

Google announced that it would begin experimenting with display ads on Image Search on August 2008. Until recently, after servral month's test, this services had been brought out from the laboratory. In 2006 the company estimated that it was missing $200 million a year because the ads was not included into image search results. It was said that Google has previously tried to incorporate text ads into results, but abandoned the practice after seeing a marked decline in traffic(From techcrunch.com). Anyway, it appear again and hopefully the traffic will not drop this time. Different with the Ads that was found by other internet surfer(image shown below),

the Ads shown now are purely written in text just like the Ads shown on web search results.

We can't doubt that there will be more and more useful or no-use ads shown on Google image search results soon.

Introductions of Search Engines

Aug 13, 2008

The world of internet changes every second. I got to know the power of search engines when I was not working in this area.

Basically, there are two kinds of search engines: crawler-based robots and manually-controlled directories. No matter in how different ways, their principle is to gather listings of URL and to make it available to be searched.

Manually-Controlled Directories

A manually-controlled directory, such as the Open Directory (DMOZ), depends on human effort for its listings. Webmaster who wants to have their websites listed on this kind of directories submits a short description. Editors approve their description or write a new one after their reviews. The listings on the directories will not change as the content on the website changes.

Crawler-Based Robots

It costs too much human labors and time to gather the listings. So human made the robot to work for them. Crawler-based search engines, such as Google, Yahoo, crawl everywhere on the internet, creating their listings automatically, which make the search actions much easier and more popular. Crawler-based search engines visit the websites frequently, and keep their listings up to date.

"Hybrid Search Engines" Or Mixed Results
MSN Search is more likely to present human-controlled listings from LookSmart. However, it also present crawler-based results (as provided by Inktomi), especially for more obscure queries.
Apparently, no matter which kind of search engines you would like to use, they are popular today because they are useful, although not too much people are aware of it.

Just because of these search engines, the new generation of marketing: Search Engine Marketing is growing in a tremendous speed. As the number of sites on the web increased in these few decades, search engines started appearing to help people find information quickly. Search engines developed business models to finance their services, such as pay per click programs. More and more related services become available.
