Websites can no longer be a basic showcase of your company. At most you will have a really pretty sign for people to look at, but will not bring traffic from the outside. A search engine does not care how pretty your website is, only the content within it and how many people link to your site. In changing with the times, websites must now have more text information on them than ever before. Even with perfectly designed keywords, tags, etc..., your website is still unimportant to google until people start linking to it or it has the exact text that was searched for. There are 3 main ways of creating link traffic, and each have their own drawbacks.
One is to purchase links, which is very difficult to do successfully because search engines now have safeguards that do not count the portals that these providers usually use.
Another is to network, in real life, with news and publishing companies and get articles about your company and website written up. News companies have legitimate high ranking with search engines and if they link to your site it is usually as solid of a backlink as you can get.
The third is to create detailed and specific articles about your line of business. The more the better. The goal of writing these articles is to have text strings indexed by the search engines that are low popularity. If google finds an exact match of a complex text string on your website it gives it incredible rank boost on the search. Only websites with that exact text string will be able to get that same boost, and it then becomes a battle of who has the highest domain & page ranking. If your website, and the articles within it, cover a myriad of topics and keywords related to your business, search engines will know where to go when those keywords are searched.
Joomla! was designed as a publishing system to allow people without HTML knowledge to create website articles. With this ability you can also edit articles, which means as a company it is very simple for even a low level employee to be able to update weekly/daily specials or promotions for a business.It also allows the publishing of articles and write-ups that will help drive traffic to your website.
