How can i do a good optimization on my joomla site?

Just like in any other websites. Title, description and keywords for every page. As well as normal off-page SEO.

Hi,
If your website is running on Joomla , then you might consider following to optimize:
>>Turn on Gzip Compression
>>Optimize JoomlaTemplate
>>Optimize your database.
>>Turn off unwanted components
>>Install Query Cache Component
>>Turn off Statistics
>>Install the PHPSpeedy Plugin
>>Optimize your index.php file
>>Turn on Joomla Cache e.t.c

You might want to consider those things no matter what platform your site is running on! Except some of them that don't apply for non-Joomla sites. However most of those things apply for any website regardless of the platform that it's running on. To do good SEO optimization of your Joomla site one must adopt proper good on-page SEO techniques that are proven to work and have a good effect on your overall SERP ranking (where you show in the SERP results) And that's Search Engine Results Pages of course. But for that you will lilely need good off-page SEO as well which includes backlinks mostly. Fortunately you can get all the off-page SEO (backlinks) that you will likely need right here on SEOClerks itself. Just visit the SEO Marketplace or check out the link building category to find many high quality link building services that will help your site to rank higher up in the SERPS so you can get more traffic and sales. Which you can then invest in a better looking, faster running, more optimized website which will result in more sales and earnings for your business.
