How Do Search Engines Work - Web Crawlers

Posted by admin

It is the search engines that at last bring in your site to the notice of the prospective customers. Therefore it's better to know how these SEs actually work and how they deliver info to the customer initiating a search.

There are basically two types of search engines. The 1st is by robots called crawlers or spiders.

Search Engines use spiders to index websites. Once you submit your website pages to a search engine by completing their required submission page, the search engine crawler will index your entire site. A ‘spider’ is an automatized program that is run by the search engine system. Spider visits a web site, read the content on the actual site, the site's Meta tags and also follow the links that the site connects. The spider then returns all that information back to a central depository, where the data is indexed. It will visit each link you have on your website and index those sites as well. Some bots will only index a certain number of pages on your site, thus don’t create a web site with 500 pages!

The spider will periodically return to the sites to check for any information that has altered. The frequency with which this happens is determined by the moderators of the search engine.

A spider is almost like a book where it contains the table of contents, the actual content and the links and references for all the websites it finds during its search, and it may index up to a million pages a day.

Example: Excite, Lycos, AltaVista and Google.

When you ask a search engine to locate information, it is actually searching through the index which it has created and not really searching the Web. Different SEs produce different rankings because not every search engine uses the same algorithm to search through the indices.

One of the things that a search engine algorithm scans for is the frequency and location of keywords on a web page, but it can also detect artificial keyword stuffing or spamdexing. Then the algorithms analyze the way that pages link to other pages in the Web. By checking how pages link to each other, an engine can both determine what a page is about, if the keywords of the linked pages are similar to the keywords on the original page.

SEARCH ENGINE OPTIMIZATION

Posted by admin

Search Engine Optimization is a process of choosing the most appropriate targeted keyword phrases related to your site and ensuring that this ranks your site highly in search engines so that when someone searches for specific phrases it returns your site on tops. It basically involves fine tuning the content of your site along with the HTML and Meta tags and also involves appropriate link building process.


The most popular search engines are Google, Yahoo, MSN Search, AOL and Ask Jeeves. Search engines keep their methods and ranking algorithms secret, to get credit for finding the most valuable search-results and to deter spam pages from clogging those results. A search engine may use hundreds of factors while ranking the listings where the factors themselves and the weight each carries may change continually.


Algorithms differ so widely that a webpage that ranks #1 in a particular search engine c rank #200 in another search engine. New sites need not be "submitted" to search engines to be listed. A simple link from a well established site will get the search engines to visit the new site and begin to spider its contents. It can take a few days to even weeks from the referring of a link from such an established site for all the main search engine spiders to commence visiting and indexing the new site.

revenue sharing forum

Posted by admin

A revenue sharing forum shares earnings with its members since without members there wouldn't be a forum. This is usually done with some kind of affiliate program such as Google AdSense. There would be AdSense advert blocks around the forum. If you reply in a topic you will be entered in a rotator of who's AdSense block shows up and you will earn some of the revenue coming from that topic.

It can also be done by paid to post. Paid to posts usually pay every month. They take total earnings and choose a percent of it that gets paid to members. Once they know how much they want to pay to members they divide that number by the number of posts. Then they award each member money or points for each post that they have.

  • You must have an AdSense account through Google.
  • You must have at least 50 total posts within the forum to participate (once you reach that level, the ads displayed from that point forward are retroactively applied to all the threads you started or participated in).
  • For threads you start, your AdSense client ID will be used 50% of the time when the thread is viewed as a thread.
  • Your AdSense client ID will be used 50% of the time when the thread is viewed by post (and you made the post).

Above are some of the restrictions for participating in revenue sharing.

Different revenue sharing sites has different ratios and restrictions. Some forums show 50% ads from the users while some show 50% ads for charity purposes.
