Using Google to search quality

This post is a continuation to the previous post.

What bothers me is that CryptLoad wouldn't even appear on Google "rapidshare downloader" search first page. Live.com didn't have CryptLoad on the first page either, but it did have RDown. It's a bad Firefox add-on neither Google nor Yahoo found worth mentioning. Maybe better so? Live also was the only service which showed two linux-based applications on the first page. I thought it belonged to Microsoft...
CryptLoad did appear on the Yahoo first page along with bad results.

It's even worse for JDownloader. Yahoo had a link to JDownloader only on the 18th page! How can two of the best applications be so low?

I started to play with google search to find out, what searches can help find more relevant results. All I do is writing down the Google result count.

It's important for these Rapidshare downloaders, that they adapt to Rapidshare changes. If an application was good yesterday, it doesn't mean it's good today. So I chose Google option "past month". Now JDownloader has twice as many hits as the runner-up, and't it's good.

  Name (all time) (by month)
CryptLoad 834000 37200
JDownloader 405000 29900
Rapidshare Plus 320000 16400
Raptor 367000 14400
RapGet 346000 10100
letolto 167000 5140
RapidLeecher 62400 2900
RapiDown 46800 1180
Unlimited File Downloader 40300 994
Downloader.NET 28600 904
Rapget.RS 26200 171

Quality level
I found that COUNT_MONTH(rapidshare [application]) / (COUNT(rapidshare [application] doesn't work) + COUNT(rapidshare [application] error)) represents quality good. There's some sense in it - we want to count bad comments and at the same time make sure the development has not stalled. We need active changes but few mistakes.

I don't think letolto is accurate because a lot of complaints about it must be in gibberish, it's native language. All else seems right. Notice how "Unlimited File Downloader" is high. Spywares/Trojans/etc can have very good quality, so I also try to measure, how good the application is for users - praise level.


Praise level
It's not straightforward to filter out praising comments, I'll stick with the word "awesome". So praise level is COUNT(rapidshare [application] awesome) / COUNT(rapidshare [application] doesn't work)
Error is not included in praise level, because people can enlist errors yet like the application. In fact, for very bad applications, the reaction is less specific.

Rapidshare Plus  4,613953488
Downloader.NET  2,256756757
RapiDown  1,641242938
JDownloader  1,628272251
Raptor  1,608
CryptLoad  1,19941349
RapidLeecher  1,068965517
RapGet  0,817343173
letolto  0,621052632
Rapget.RS  0,316770186
Unlimited File Downloader  0,059815951

Here "Unlimited File Downloader" has plummeted down, noone praises it. Rapidshare Plus despite it's lacking quality really seemed praised a lot on the internet. I have no idea why RapiDown is so high or CryptLoad so low. I think I'm seriously lacking in my praise level estimation formula.


Final ranking
I can't come up with a good formula for this one. I'd just use quality ranking and ditch the lower part of praise ranks completely.
1. JDownloader
2. CryptLoad
3. Rapidshare Plus
4. RapidLeecher
5. RapGet
6. RapiDown
7. Raptor
I can't put letolto anywhere in this ranking due to it's internationality problems.
