These are search engines that will automatically list your website, with the best example being Google. With this type of search engine, if your web site changes then your listing will change. There are 3 parts to the way these search engines work and these are:
1.The Spider - also knows and the crawler or robot. The spider will travel around the internet reading web pages and the code that makes them up and also follow and links to other web pages. Once a site has been visited by a spider it is said that the site has been "spidered" or "crawled". On a monthly basis the spider will revisit all old sites and find any new ones through the links from these sites. All the results of its work are stored in:
2.The Index - this is a database that contains a copy of every web page that has been spidered. If a web page changes then the database will be updated. There can often be a delay between the site being spidered and indexed. If a site is not indexed then it will not be seen by a user of the search engine. The search results that are found by the user of the search engines are pulled out by:
3.The Software - this will go into the database and rank all of the sites in order of relevance for each search term. This rank depends on the rules that are set up for that particular search engine and will be different for each one.
Human-Powered Search Engines
These are more commonly called directories and sites must be submitted by the owner for them to get listed. There are various types and some are free and some are paid. All entries must be reviewed by the editor and approved before they are submitted. All searches of the site are done through the text in the title and the description given to the site. If your site changes then your listing will not change.
Hybrid Search Engines
These are a combination of both crawler-based and human-powered search engines. Most of these will have a bias to either submitted sites or crawled sites and so you may find that submitted sites appear higher in the search results even if they are less relevant.
Conclusion
Even if 2 different search engines have indexed all of the same sites then the results that visitors see may be different depending on how each engine's software ranks the sites. In order to rank highly in as many search engines as possible it is important to learn as much about their rules to ranking as possible and do the necessary things to your site.
Engines How They Work
If you are asking this question, you are not alone. Many small business owners and people who are self employed understand they need a website, but don't have a clue how to make visitors come to it. The truth is, understanding websites is pretty simple; bringing tons of visitors is another topic altogether though. Let's start with how search engines work to index your website and what is so vital about them.
What are Search Engines?
Search engines are like phone books for the internet. In the same way you look to the phone book to find a local business, a search engine allows you to look for online businesses. You simply type in the word or words that represent what you are searching for and you get a list of possible sites. The search engines use what they call “spiders” to crawl the internet and index websites by term. For example, a spider from a search engine would crawl through your site and see the word shoes. If “Shoes” is the most used word on your web page, you'll get indexed for shoes, along with every other site using that word. However, if your site uses the term “Shoes Boston,” you would be indexed for that term. For this reason, you need to include words relevant to what you are selling or offering.
Why are Search Engines Important?
The majority of people use search engines to find what they are looking for. No matter how much you advertise your website and url, the fact is very few people will remember it. Most people simply search by the name of your company or the industry it is a part of. However, all search engines only lists ten search results on each page. Statistics show that very few people go past page two of the search results. Therefore, if you are on page nine or you are listing 150,000 out of one million, you may never get seen.
How Do You Get On Page One Or Two Of Popular Search Engines?
Having your site displayed on page or two of the most popular search engine results is not easy. There are a number of things to consider such as keywords, meta tags, headers, and even the website name you choose. You also have to know which sites to link to and which to stay away from. It is not an easy process, but with a little time and determination, you can get your site up there. The process is called SEO or search engine optimization. If you do a search for either term you will quickly see that it is the foundation on which search engines work. There are companies that do nothing but optimize websites each day. There are also sites that sell links to promote your website. Some of these sites are great; they help you get on page one and develop a good website. However, some companies use techniques that are not so prudent and can not only keep you off page one, but they can also get you banned from the search engines all together.
What Should You Avoid?
Avoid using companies that stuff your pages full of keywords or link you to hundreds of sites in one day! These techniques are not useful and the major search engines will quickly catch on. You need to use techniques that build your site up in a natural order that would occur without these companies. You should slowly add links, use lots of new relevant content, and grow your site over time. Do not try to force the process or use bad techniques. Do things correctly and you will quickly be on page one of the search results.
