The 3 Parts Of A Search Engines? T he spider, also called the crawler. The spider visits a web page, reads it, and then follows links to other pages within the site. This is what it means when someone refers to a site being "spidered" or "crawled." The spider returns to the site on a regular basis, such as every month or two, to look for changes. Everything the spider finds goes into the second part of a search engine, the index. The index, sometimes called the catalog, is like a giant book containing a copy of every web page that the spider finds. If a web page changes, then this book is updated new information. Search engine software is the third part of a search engine. This is the program that sifts through the millions of pages recorded in the index to find matches to a search and rank them in order of what it believes is most relevant.
The process involves developing both hidden codes (Meta Tags) as well as the text copy of the site and combining them to create relevancy to the target Key Word Phrases and then registering with the search engines to “Optimize” the web site. Source: http://www.ed-u.com/titles.htm Titles and Tags The title of a webpage is the text that you can see in the left hand corner of the top bar of your browser software window. Search engines regard the titles of your pages as the most important keywords or keyphrases when indexing your site. Additionally, when scanning search results, visitors will read them they same way that they read headlines in a newspaper. Make them count! Title tags, etc. Include the most important keywords and keyphrases associated with your products or services in different title tags right across your web-site. Make sure you use titles that reflect the content on each webpage. Bear in mind that if the page is bookmarked by a visitor, the title is what they will see in their favorites file . Repeat the page title in the first header tags on some pages and very important keywords in the first header tags on others. Use headers that support the content on that page. Repeat the contents of title tag throughout your text. Use the "BOLD" tag for important keywords and keyphrases . Header tags A header tag is a piece of code that displays text as a heading, typically, but not exclusively, for a paragraph. There are six header tags. H1 is the largest and H6 the smallest. Header tags = H1 Header tags = H2 Header tags = H3 Header tags = H4 Header tags = H5 Header tags = H6 You can use more than one header per page. Underline tags Bold Tags IMAGE ALT tags are tiny pop-up boxes of text that appear when you position your mouse cursor over a webpage image. If you include these tags, it not only helps your visitors who are browsing with their images turned off, but also some search engines will index this text , so it could help your rankings. Be sure to use your most relevant keywords in these tags. They of course also need to be relevant to the picture that they refer to. META Tags META tags are not visible to your visitors, but contain information that some search engines can use to help your ranking within their results. What does the word "META" as in "META tags" mean? The word "META" means situated behind or beyond, therefore "META tag" means tags (HTML code) that are situated on the webpage, but not visible to the viewer. Whilst META tags are useful, they cannot compare to the high importance of your title tags and the keywords that your visitors can actually see on your webpage. Search engines have diverse criteria for ranking web-sites, so you should use varying META tags for different pages. The more varied the content of your META tags, the better, as this gives more opportunities for your pages to achieve a high ranking across a range of search engines. Apart from the obvious reason, you need a high ranking in as many places as possible to cut down on the percentage of your business loss if your position slips (or you disappear completely from the listings) within a highly trafficked search engine. Mixing your METAs Use different META Tags on different pages: In the META name="keywords" list use: lower case Capitalization UPPER CASE iNVERTED tEXT Misspellings Hyphenation Join words i.e. ice cream = icecream, ice-cream Pluralizations = icecreams, ice-creams Use commas to separate key words and key phrases within your META tags on some pages, on other pages just use spaces. Extensions i.e. fast = faster, fastest. Many search engines use string queries when indexing sites.
