When a search engine spider or crawler, crawls a website, then it is up to the webmaster to show the pages that he wants to crawled and hide the ones that he doesnt. There are a few things that should be taken into account, before a website can be made available for crawlers.
A website needs a proper structure, because it is good for both the search engines and users. If a webmaster wants to make the most of the important web pages, then he needs to divide them into categories. For example, a common site structure consists of a home page, category pages, subcategory pages and detail pages.
The detail pages are the ones that contain product descriptions. This structure is ideal for those websites that are small. However, if a website has millions of web pages, then it is best to adopt the faceted navigation option. Faceted navigation help users eliminate the pages that they are not looking for, through the filter option.This can be done by narrowing down the category through location, age, or sex.
Controlling The Crawling
A webmaster can control the pages that a crawler crawls. If he wants to block a number of pages, then he can use robots.txt file and rel=nofollow. Meta tags can be used by webmaster as well, as they control the way Google crawls a website. If the Meta tags are placed in the head section of a page, then they tell Google not to index it, not to crawl the links on the page, not to index the images on the page and not to use the snippets on the page in search engine results.
Indexing is when information is added, about a web page to the index of Google or any other search engine. An index has many web pages, and it can be called the database. The information that this database holds, is the one that was crawled by search engines in the first step. When a crawler goes to web pages, it indexes detailed data about the content and topic relevance of every web page, it includes a map of the pages that are linked through internal links, the anchor text, and whether there are ads present on the web pages or not.
When web pages are indexed, then they are ranked according to their relevance and importance. Relevance means, whether the content on a web page, matches the user intent or not. Similarly, a web page becomes important if it is cited on other web pages; for example, Wikipedia cites an article, would give importance to that link. Search engines have algorithms through which they rank web pages.
