MSN & Yahoo, the other two of the 'big three' have their own proprietary versions of spiders.A search engine crawler is your best visitor. Giving a crawler easy and uninhibited movement in your website is necessary for good search engine rankings. Your website must be spider (search engine) friendly if you want any traffic from the search engines. A search engine spider does not read your website the way we humans do. The spider reads web-page source code (HTML) that renders your page, therefore ‘bad code’ can be an impediment to the spider, sometimes causing it to give up crawling your website.
