How is it possible that my thread on the Joomla.org Forum about my website ranks higher (much higher) than my own site? [...]What is Joomla.org & MacNN Forum and the newspaper doing that's helping the hits rank so high on Google?
Because
* the page rank of rockettheme.com is higher then your site
* more sites link to rockettheme.com
I've heard about Sitemaps and Meta Descriptions/Keywords and things like that, but even when I have those things it didn't help
Attention, tuning websites for better ranking in google is not a realtime task. it taks time. If you change something on your websites, it depends on the google spider when he come back to scan your site again.
There are metatags for it, but if you set them to (e.g) 2 days, and you dont have much new/changed content on your site, the bot will come less often.
So IMHO a very important step is, to use the url-rewriting feature of joomla. This will build clear url und the changes are much higher to get an full index of your pages. (2 Years ago, every site with
www.example.com/index.ext?something
(get parameter) was ignored and not being indexed.)
Second: Take full use of the meta tabs in your content, where you can insert keywords, description and such things. Use keywords or word-combinations that aren't on the page in combination with important keywords which are on the page. (e.g. "steve nguyen")
Let me show you some examples:
www.bestheads.com
<- my company's homepage.
www.entermedia.at
<-- site of a customer.
search for entermedia:
www.google.com/search?hl=de&q=entermedia
Customer rank 1
Our site rank 4
Google change their ranking one in a while (so every 2 months). it is possible, you are 2 months rank 1 and suddenly you are on the second page.
hope it helps
