Keyword density is an indicator of the number of times the selected keyword appears in the web page. But mind you, keywords shouldn’t be over used, but should be just sufficient enough to appear at important places.
If you repeat your keywords with every other word on every line, then your site will probably be rejected as an artificial site or spam site.
Keyword density is always expressed as a percentage of the total word content on a given web page.
Suppose you have 100 words on your webpage (not including HMTL code used for writing the web page), and you use a certain keyword for five times in the content. The keyword density on that page is got by simply dividing the total number of keywords, by the total number of words that appear on your web page. So here it is 5 divided by 100 = .05. Because keyword density is a percentage of the total word count on the page, multiply the above by 100, that is 0.05 x 100 = 5%
The accepted standard for a keyword density is between 3% and 5%, to get recognized by the search engines and you should never exceed it.
Remember, that this rule applies to every page on your site. It also applies to not just to one keyword but also a set of keywords that relates to a different product or service. The keyword density should always be between 3% and 5%.
Simple steps to check the density:
Copy and paste the content from an individual web page into a word-processing software program like Word or Word Perfect.
Go to the ‘Edit’ menu and click ‘Select All’. Now go to the ‘Tools’ menu and select ‘Word Count’.
Write down the total number of words in the page.
Now select the ‘Find’ function on the ‘Edit’ menu. Go to the ‘Replace’ tab and type in the keyword you want to find. ‘Replace’ that word with the same word, so you don’t change the text.
When you complete the replace function, the system will provide a count of the words you replaced. That gives the number of times you have used the keyword in that page.
Using the total word count for the page and the total number of keywords you can now calculate the keyword density.
How Do Search Engines Work - Web Crawlers
It is the search engine that finally put your website to the attention of potential customers. Therefore, it is best to know how these search engines actually work and how to present information to customers to initiate 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 send your web pages search engine to complete their required submission page, the search engine spiders index your site. A "spider" is an automated program that is managed by the system's search engine. Spider visits a web site to read the page content, meta tags of the site and follow the links that the site connects. The spider returns all that information to a central repository where data are indexed. We will visit each link you have on your website and index those sites as well. Some spiders only index a certain number of pages in your site, so do not create a site with 500 pages!
The spider periodically on site to verify any information that has changed. The frequency with which this occurs is determined by the moderators of the search engines.
Spider is almost like a book that contains a table of contents, actual content and links and references to all the sites located during the search, and can crawl up to a million pages a day.
Example: Excite, Lycos, AltaVista and Google.
When you ask a search engine to locate information actually is to search the index created and not actually searching the Internet. Different search engines produce different rankings because not every search engine uses the same search algorithm indexes.
One of the things the search engine algorithm scans for the frequency and location of keywords on a web page, but it can also detect artificial keyword stuffing or spamdexing. Algorithms then analyze how the pages of links to other pages on the Internet. By checking how pages link to each other, an engine at a time to determine what a page is about, if the keywords of the linked pages are similar to keywords on the page.
It is worth cataloging the basic principles to be enforced to increase website traffic and search engine rankings.
