How Do Search Engines Work

How Do Search Engines Work - Web Crawlers | It is the search engines that finally bring your website to the notice of the prospective customers. Hence it is better to know how these search engines actually work and how they present information to the customer initiating a search. There are basically two types of search engines. The first is by robots called crawlers or spiders. 

Search Engines use spiders to index websites. When you submit your website pages to a search engine by completing their required submission page, the search engine spider will index your entire site. A ‘spider’ is an automated program that is run by the search engine system. Spider visits a web site, read the content on the actual site, the site's Meta tags and also follow the links that the site connects. The spider then returns all that information back to a central depository, where the data is indexed. It will visit each link you have on your website and index those sites as well. Some spiders will only index a certain number of pages on your site, so don’t create a site with 500 pages!

The spider will periodically return to the sites to check for any information that has changed. The frequency with which this happens is determined by the moderators of the search engine. A spider is almost like a book where it contains the table of contents, the actual content and the links and references for all the websites it finds during its search, and it may index up to a million pages a day.

Example:  Excite, Lycos, AltaVista and Google.

When you ask a search engine to locate information, it is actually searching through the index which it has created and not actually searching the Web. Different search engines produce different rankings because not every search engine uses the same algorithm to search through the indices. 

One of the things that a search engine algorithm scans for is the frequency and location of keywords on a web page, but it can also detect artificial keyword stuffing or spamdexing. Then the algorithms analyze the way that pages link to other pages in the Web. By checking how pages link to each other, an engine can both determine what a page is about, if the keywords of the linked pages are similar to the keywords on the original page.

The Importance of Search Engines

The Importance of Search Engines | It is the search engines that finally bring your website to the notice of the prospective customers. When a topic is typed for search, nearly instantly, the search engine will sift through the millions of pages it has indexed about and present you with ones that match your topic. The searched matches are also ranked, so that the most relevant ones come first.

Remember that a prospective customer will probably only look at the first 2-3 listings in the search results. So it does matter where your website appears in the search engine ranking.

Further, they all use one of the top 6-7 search engines and these search engines attract more visitors to websites than anything else. So finally it all depends on which search engines the customers use and how they rank your site.

It is the Keywords that play an important role than any expensive online or offline advertising of your website.

It is found by surveys that a when customers want to find a website for information or to buy a product or service, they find their site in one of the following ways:

• The first option is they find their site through a search engine.
• Secondly they find their site by clicking on a link from another website or page that relates to the topic in which they are interested.
• Occasionally, they find a site by hearing about it from a friend or reading in an article. 

Thus it’s obvious the the most popular way to find a site, by search engine, represents more than 90% of online users. In other words, only 10% of the people looking for a website will use methods other than search engines.

All search engines employ a ranking algorithm and one of the main rules in a ranking algorithm is to check the location and frequency of keywords on a web page. Don’t forget that algorithms also give weightage to link population (number of web pages linking to your site). When performed by a qualified, experienced search engine optimization consultant, your site for high search engine rankings really does work, unless you have a lot of money and can afford to pay the expert. With better knowledge of search engines and how they work, you can also do it on your own.

Learn SEO | Use Keywords In Page Titles

Learn SEO | It is recommended to use keywords in page titles itself. This title tag is different from a Meta tag, but it's worth considering it in relation to them. Whatever text one places in the title tag (between the <title> and </title> portions) will appear in the title bar of browsers when they view the web page. Some browsers also append whatever you put in the title tag by adding their own name, as for example Microsoft's Internet Explorer or OPERA.

The actual text you use in the title tag is one of the most important factors in how a search engine may decide to rank your web page. In addition, all major web crawlers will use the text of your title tag as the text they use for the title of your page in your listings.

If you have designed your website as a series of websites or linked pages and not just a single Home Page, you must bear in mind that each page of your website must be search engine optimized. The title of each page i.e. the keywords you use on that page and the phrases you use in the content will draw traffic to your site.

The unique combination of these words and phrases and content will draw customers using different search engine terms and techniques, so be sure you capture all the keywords and phrases you need for each product, service or information page.

The most common mistake made by small business owners when they first design their website is to place their business name or firm name in every title of every page. Actually most of your prospective customers do not bother to know the name of your firm until after they have looked at your site and decided it is worth book marking.

So, while you want your business name in the title of the home page, it is probably a waste of valuable keywords and space to put it in the title line of every page on your site. Why not consider putting keywords in the title so that your page will display closer to the top of the search engine listing. 

Dedicating first three positions for keywords in title avoiding the stop words like ‘and’, ‘at’ and the like is crucial in search engine optimization.
