By 06 new digital data had grown to 161 billion gigabytes This volume is believed to be 3 million times the information in all the books ever written.It is multiplying at an accelerating pace, more than double of information each year. By 2010, it is foreseen to hit 1,000 billion gigabytes (a zettabyte). This is new digital information — in summation to the vast amounts produced in each previous year.
How does anyone ever find anything in amongst all of that?It is not surprising that search engines have become massive businesses and information constitution is the hot career choice of the decade.
When it comes to your website is concerned the olde worlde old notion that ‘if I build it, they will come’ doesn’t cut it any more. Your website is like a graind of sand in a deser. People need to know that you exist. More of import ly, they need to see your web pages as compellingly different, so that they will chose to come to your site rather than to any one of the thousands of others out there.
If you want people to see you as better than their other options, you need to get world search engines to see you the same way.
There are basically two ways in which everything on the web is classified and indexed. The first, and oldest, is by directories. You submit a short description to the directory for your entire site,or editors write one for sites they review. Each site can only occupy one slot depends on humans for its listings, regulate where each site belongs.
There is only one directory you need to worry about. It is called DMOZ and you find it at dmoz.org. DM0Z is the foundation of the web, and all the major search engines build off it. You have to submit your site to DMOZ, and then wait, very much for many weeks, for mortal to get roughly to looking at it.
If you are not already in DMOZ, it can take Google a very long time to find you. Google is not a directory; it is a search engine, the second way in which information is sorted and identified on the web. While directories are run by people, online search engines are automated. Their fieldwork is done by small bits of code called bots or spiders.
This code scurries around the web, following hyperlinks. Every page it encounters is absorbed and taken back home, where it is deposited in a vast database that indexes web pages.
When a spider absorbs a web page, it takes the obvious text, the buried code, the names and addresses of pages and files that the page links to, and the details of pages that link into it from elsewhere. The indexer takes all this information and crunches through it in detail. It then comes up with an understanding of what the page is about.
When someone enters a search query, typically a word or phrase, the search engine retrieves all the pages that relate to the query. It processes them by means of an algorithm that looks at more than 100 different characteristics, and then ranks the pages according to how relevant they are to the query, how good the content is, and how important the page is relative to all the competing pages on the web that are about the same theme. If you want your page to get into the top two or three out of thousands for any given keyword, your site has to be one of the very best in its field.
A keyword is a word or short phrase used to encapsulate the essence of a web page. The best search engines use it to variety what a page is about, searchers use it as a search query to find pages that may form their problems, and marketers use it to trigger advertisements that will lead searchers to their site. online search engines profit the keywords for a page from a number of places, including:
the content and context of the web page
the anchor text of inbound links to that page
the title, description and keyword meta-tags in the code of the page
the description of the page in web directories
the tags assigned to the page by social bookmarkers
the algorithms of the search engines themselves
The algorithms of search engines are complex mathematical and statistical models that weigh and read all of the factors associated with a page, in isolation and collectively. Since search engines compete with each other to yielding the best possible search lead s to their users, their algorithms are black boxes, and are guarded more closely than the recipe for Coca-Cola.
The newest trend in search engines, and likely the future of search in general, is to move away from keyword-based searches to concept-based searches. In this new form of search, rather than limiting a search to the keywords you input, the search engine tries to figure out what those keywords mean, so that it can suggest pages to you that may not include the accurate word, but notwithstanding are topical to your search. This is still a developing field, but so far seems to have a lot of potential in devising searches more relevant, making the web an even easier place to find exactly what you’re looking for.
