About Search Engine Optimisation


Search Engine Optimisation (often abbreviated to SEO) refers to the process of improving the volume and quality of traffic to a Website from search engines. A site that has been optimised according to SEO practices is said to be Search Engine Friendly (often abbreviated to SEF).

A somewhat important SEO technique that also helps your users is using Search Engine Friendly URLs. See Enabling Search Engine Friendly (SEF) URLs for more information.

Dynamic MetaDesc in a list of articles by category

When you view a list of articles by category, joomla put into the page the default configuration metadescription, but perhaps we want write the category description into the metatag for SEO reasons.

For this we need open the file includes/application.php.

Search for this piece of code in the function &getParams:

$params->def( 'page_title'      , $title );
$params->def( 'page_description', $description );

Add this code before:

if (strcasecmp($_GET['view'],'category')==0) {         
   $description = $database->GetOne("SELECT description FROM #__categories WHERE id={$_GET['id']}");       
}

Now the metadescription is more dynamic when you view a list of articles by category.

Change default SEF suffix from .html to .htm

If you need to change default article SEF suffix from .html to .htm (for example, if you need to move static site to Joomla and keep existing urls with .htm extensions), you need apply following patch to includes/router.php (working on Joomla 1.5.9, should work on other 1.5.x versions):
