Nope. It's not going to happen. I've read "which parking company is best" threads at a number of forums. They're a load of Bologna Sauce, by a LARGE measure.
How do I know that? Well, when the actual numbers (RPC, RPM) occassionally leak out it's stunning to compare those numbers with the claims of profits and success. Either the person reporting their RPC/RPM has utter garbage traffic - which I'm afraid is fairly common - OR the parking company simply cannot get a better deal with the feed providers based upon the quality of the domains in their aggregate portfolio. Still, that doesn't stop the fanboys from chiming in in the "rating thread" with "CompanyX is the best". Phooey.
Notice the point: Larger portfolios of better domains means the parking firm is able to negotiate better deals with feed providers. Makes sense, doesn't it? More money for better quality?
However larger parking company isn't always synonymous with better customer service and sometimes you need someone to walk you through a process or to solve a mystery. Do you value customer service? Then you have to take the experience route.
1 vs. 2 click landers? Again, case by case.
My next suggestion is that you notice the quality of the domains associated with the different landers. That's a good place to start. Even the better/larger parking firms have crapola domains in their aggregate portfolios, but there's no mistaking the better domains.
Revenue split? Each firm has a different offer. Many don't publish the split. Some firms offer a better split based upon the quality of your portfolio. How will you know which one offers the best split? Only by showing them your portfolio and/or the traffic it generates.
There's ways of learning how many domains the bigger players have pointed to their servers and there's ways of learning what the quality of domains are that are being added to their servers. That's not the end of the story as many domainers also use their own redirects, but for the most part, there's no mistaking the landers.
Ultimately, the only way that anyone knows which parking company is best for their domain portfolio is by moving their domains around. Supposedly some firms offer better deals for international traffic.
It is reported that some domains may work better with Yahoo feeds than with Google feeds.
Then there's the question of your ability to control the text links on the landers in order to optimize the domains for the natural traffic. Not all landing companies offer the same level of control, so while they may offer the same feed the lander optimzation may take longer or may not be optimal when compared to more granular control.
There's just too many variables to offer a simple answer and that's the reason why most voting threads are utter BS.
Lastly, unless the person "voting" puts up a healthy cross-section of their domain portfolio for analysis and cross-company comparison the assertions that "company C is the best" is little more than noise in a vaccuum . . if you know what I'm saying.
Analyze and apply what I've explained and you will be much farther along than you ever will by reading a voting thread. Voting threads are mostly promotional crap and since I'm in charge of the crapper they get flushed. Sorry. End of voting story.
