Quality of Translation:
JTrans PRo lets you choose between Google or Yahoo to translate the text. Google has recently updated its method of translation and I feel it gives better results (only tested French and Chinese). A lot of the translated text is still sometimes funny, but still understandable. It doesn't beat manual translation and probably never will, but visitors who aren't good at reading English appreciate it. After adding JTransPro on my website, I received some non-english comments that I never had in years. Those comments hint that people who do not understand English are still visiting my website and find that the computer-translated content is still understandable.

Search Engine Results:
After installing JTrans Pro, my website has went from not within the first 10 page to 1st page as the 3rd to 5th result for a specific two-word keyword on Google. I now receive around 3000-5000 visits/day from Google and about 7000/month from Yahoo. My Yahoo traffic is increasing considerably every month while my Google traffic is increasing very slowly. There are many factors that increased my websites search engine rankings, but I feel that JTrans Pro is a contributing part of it. When I google search "site:mydomain.com", it shows all the pages on my website and my website shows over 11,000 results and most of them are the translated web pages. Of all the website on the first page of Google for my two-word keyword, only four of them did not have over 5000 pages of results. So that is why I believe the number of pages on your website is an important factor in search engine results.

With Google Analytics, I noticed a few months after installing JTransPro that I was getting more visits from countries where English is not a primary language (ex. Vietnam, Mexico, Taiwan, etc.) and when I look at the referring search engine words/phrases statistics, I found a lot of non-English keywords. Those keywords bring in about 100-500 visits/month (varies a lot).

Performance:
It's really fast. Usually when you translate a page, you have to wait a while for Google to translate it. But with JTrans Pro, it stores a cache so that it loads immediately without having to wait for GOogle/Yahoo to translate the page every time.

Value:
I had to sleep on it before I decided to purchase this but I'm glad I decided to get it. If you have an established content-based website, think about getting this because it may improve your search engine results. This won't replace manual translation, but its a good alternative to it if you don't have the money to translate every page on your website.

If you have a website that makes money off selling advertising space, this is a must have. I replaced the default Joomla search with GSearch Pro and not only do I make extra money off of it, the results are better and more accurate than the default Joomla search. Instead of just using the standard Google Adsense code, GSearchPro makes the search results blend into my website template. The result is higher CTR compared to using just the standard Google Adsense Search code that doesn't display your template.

Now lets get to the most important part about this Joomla extension. Will it make more money for you? Is the ROI good? With GSearch Pro, I usually make 50 cents to $2/day on a website that receives about 150 search/day. Now if you have a website where users use the search feature on your site a lot (ex. Arcade site, directory, etc), you'll have a lot more search queries meaning more money. On my content-based website, I make about $7-$10/month from the search results so the money I spent was paid back in just four months! Now it's all profit!

Note: New pages don't show up in the search results immediately. This isn't a problem with the component; it's just the way Google works. It may take a few days for it to appear but if you want to speed it up, you can use Google Sitemaps and Google Webmaster Tool. In Google Webmaster Tool, go to Tools> Set Crawl Rate and set it to Fastest if your server can handle it.
