How the Spiders(robot) Work

This shows the spider traps, how the spider work.

the Orphan Pages means that when the spider find this page but can not find more pages. it is the only one. SO, the spider will give up and find other ways to get the links. It tells us we shall add more links on some pages to make it become a connected net.

Unfriendly SEO-CMS System means  the system is not search friengly enough for the spider to crawl from one page to another. Search Engine Friendly CMS are just like the wordpress and the joomla, Search Engine Friendly Shopping Cart are just like the Oscommerce and Zencart. Which can help you make html page and with keywords in the URL, which can help you make good layout and even make the spider feel good.

Cloaking means hidden links but they link outside, one kind way of cheating. Like changing the fond color the same as the backgound color, Making the links without the anchor test, only a href links.

Bad Server Configuration means the speed and the location of the server is bad for the visitor to experience, it’s one kind of UE(User Experience). Most people will close a web page if it can not be opened in 10 seconds, because sometimes even the malware or virus will cause similar situation. So make sure your server configuration is great, otherwise, no traffic, and no user, no customer, no sales.

Session Based Coding means URL automatic changed according the different visitors, that is one kind of cheating as well.  Session based Coding also need your make a clear html code for the pages, etc. Such session problem do great harm to a website which depends on the SEO to get the traffic.

No error handing means when you type the wrong url, there shall be a 404 pages which contains the links to your homepages and also a redirection to another website. 404 page is the most important factors though it is always ignored by many people.

Watch out the spiders!
