Search engines are like giant virtual phone directory. Even though they are composed of links and website information, still they contain the information that people needs and also a place where to "look".

They are same as a software or system that executes somewhere in the net and follows or acceptable inputs and receive it into their systems. Of course, they follow specific "rules" or actions in order to keep extracting information of all websites from different places.

In order to become "friendly" for all search engines, then must apply some routine page formats every time you make a web page or website system (e.g. dynamic links). Any kinds of links are acceptable except for abusive links and repeating contents are more likely banned.

Always to remember follow these simple tips and would probably had some little advantages:


1.) Unique page titles
The more page titles you have, the more links and contents available in the search indexes. A very good example is when query or search for contents and you see those Larger TEXTS on the search indexes, that would probably the Page titles crawled by the bots.
2.) More articles , more contents, and texts.
Since search engines are created for searching contents..... texts or articles would probably your key to success.
3.) Lessen large images or Flash animation
Currently, search engines don't crawl information with these medias. That would also include JavaScript generated contents or AJAX. Since JavaScript only executes and readable when specific web browser application is used by the users or client PCs, search engines don't read those kind of stuffs.
4.) Ordinary readable html links
It means an ordinary parsed html links within an ordinary page or dyanmic pages as long as the links are readable as ordinary links. Links that are generated by JavaScript are more like to be unreadable by search engines.
5.) Links submission
Each search engines have their own system to receive LISTS of links from the web owners. They would receive TEXT files or XML files as basis of available links available on a certain web site. YOU DON'T NEED TO HIRE SOMEONE to that for you. It can be done by yourself that is if you know how to use them without abusing their POLICIES.
