Site Review: http://www.sonirodban.com/

Hello folks. This is John Jim Fambrini. I'm an ex-CIO now retired in beautiful Thailand. I manage websites for two auto exporters here. One of these auto exporters is Soni Group and their website 2012 Toyota Hilux Vigo Thailand Pickup Truck Dealer and Exporter used to be number 1 and number 2 on most Google searches from between 2001 till 2010. In 2011 they remained on top on some searches and came down on others. In the past few weeks they have suffered a rout in their SERPs. Two weeks ago they were thrown on page 3 and 4. Now they are back on page 2 on many and bottom of page 1 on some queries. Their search terms related mostly to their best selling cars as Toyota hilux vigo, toyota fortuner, nissan navara, thailand pickup trucks and so on.

I know design has changed very little since 2003 so tips on design would also be appreciated. I really want to move it to Joomla so I have a greater selection of templates but we had moved our 4x4 Pickup Trucks Single Extra Double Cab Toyota Vigo site from static html to Joomla some 4 years ago. The site used to be PR3 but when it moved to Joomla PR evaporated and became zero. It took a few months to come to PR2, then became PR3 for a few weeks but crept back down to PR2 and has stayed there since then. Its SERPS never came back up. Is there a Joomla conversion expert who can tell me how to avoid this scenario.

Thanks again for your time. Positive and negative criticism all welcome, no need to spare my feelings.
