Generating high traffic to your web site can be costly, or not, 
depending on time and effort you commit to the business.

One of the easiest, least expensive and most effective ways to 
get visitors is via a concept called 'Keyword Density'.

The concept rests on the knowledge that search engines spider 
the Internet for sites containing keywords similar to those 
someone has just keyed into a search engine. The more times 
those words appear on your site - conditionally - the more 
chance you'll get that high ranking.

But search engines aim for relevance, too, so a site actually 
bearing little relevance to specific terms might rank high for 
a short while, until human editors come in, check it out, then 
abandon the site as irrelevant to their customers.

It's all about 'content' which for our purposes means useful 
articles, information and advice that search engines consider 
valuable to their customers, rather than pages packed with 
advertisements and little else (unless they're getting paid 
for it via pay per click promotions, of course!).

For example, 'sex' is a hot topic on the Internet and the 
subject of millions of searches every month. How wonderful 
for your site to appear to everyone searching for 'sex' - 
(one day I will rephrase that) - who happens upon pages 
offering discount holidays, printer refill cartridges, golf 
clubs, pencils, but not sex!

The point is, anyone using specific techniques to lift their 
own non-sex-related site high on the listings when someone keys 
'sex' into search engines will soon be exposed and probably 
banned for life from most search engine listings. By 'techniques'
I mean pasting the word 'sex' all over the background of your 
site selling lawn mowers, or calling your site 'Everything to 
Do with Sex' when your site bears no relevance at all to the 
'S' word.

Here are a few ways to use keyword density to increase your 
chance of a higher ranking over site owners who don't try 
quite so hard:

· Choose a domain name containing words and phrases most 
  commonly searched for by your target audience. The site  
  for my mystery shopping book, for example, is  
  http://www.mystery-shopping.org.uk. Other examples from my own  
  collection, with titles, articles, domain names based on  
  keyword density: http://www.fiveminutewriter.com,  
  http://www.propertyfront.net, http://www.resell-rights.net.

· Include your best key words and phrases in page titles, for  
  both the home page and all additional pages. My mystery  
  shopping site has pages entitled: Get Paid to Shop or Even  
  Start Your Own Mystery Shopping Business, Travel Free, Get  
  Paid to Play Golf, and articles entitled: Start Your Own  
  Mystery Shopping Business, Get Paid to Shop and Keep  
  Everything You Buy Without Having to Pay! Those titles came,  
  not surprisingly, because 'Get Paid to Shop' and 'Start  
  Mystery Shopping Business' are common terms used by people  
  seeking products like mine.

· Descriptions, keyword entries and metatags used when designing 
  your site should also contain some of the most common terms  
  used by your target audience. For a dating agency, the  
  keywords might be 'dating', 'dating agency', 'online dating',  
  and so on.

· It might be beneficial to use key words in titles for  
  pictures and graphics used on your site. For example, my site  
  http://www.boxerdog.biz has several pictures of cute boxer dogs, all  
  mine, with gifs labelled boxerdog1, boxerdog2, boxerdog3, and  
  so on. Beneath each picture there's a caption including the  
  phrase 'boxer dog'. One of my first excursions into keyword  
  analysis showed the term 'boxer dog' is keyed into search  
  engines around 46,000 times every month. Not only that, but  
  I love boxer dogs, and can think of nothing more delightful  
  than marketing products for them and their two-legged friends.   
  But, realistically, editors might consider my graphics titles  
  a bit OTT (Over The Top) and this could adversely affect my  
  rankings. I shall just have to wait and see!

· Have articles uploaded to your own and other people's sites.  
  Search engines love articles and other chunks of useful  
  information to benefit their customers, making articles one  
  of the very best ways to lift your site high in search engine  
  rankings. Again, use your keywords in page headings and  
  article titles to further increase your chances, as I did for  
  http://www.boxerdog.biz which includes articles called The Boxer Dog  
  Who Cheated Death Row and Became a Television Star Instead,  
  The Boxer Dog With the Longest Tongue, The Boxer Dog Who  
  Received Hate Mail. Make sure the articles contain links back  
  to your main web site, the one you want people to visit, and  
  try to include those same articles on other sites to increase  
  links to your main site that might also attract visitors to  
  your site.
