How to promote a page in site
Hello folks. I'm a car dealer and car exporter. When a new model of a car is released it is important to get in the first 5 searches. Our bread and butter is Toyota Hilux Vigo pickup truck (we are a car dealer from Thailand). All new 2014 Toyota Vigo is being released and we created a web page (http://toyota-dealer.org/2014-toyota...nge-model.html) about it but when we type "toyota hilux vigo 2014" "all new toyota vigo" "2014 toyota vigo" and searches like this, we are not even on 1st page. The funny thing is we were number 1 and number 2 for almost 1 year in late 2012 and early 2013 when we were not even trying to rank for these search terms and did not do any SEO to get this ranking.
What can we do to restore the fortunes of this page and site for searches related to this search. Any help would be appreciated.
