Early last week, CodSpot asked me to review this product. Initially, I turned him down, as I rarely accept reviews anymore. But then, curiosity got the better of me and I told him I would test it out on an old site that I already has a Facebook Like button on.
The website that I'm testing it on, gets approximately 4,500 - 6,000 uniques a day. I installed the original Like button on it a couple months ago. Over the course of about 2 months, it had gotten 132 likes. Not bad. This is where it was on June 16th at 10:25pm CST.
Since installing the code from CodSpot, the likes are currently at 436 - wait, just refreshed the page and they are at 438.
Just running the numbers:
60 days == 132 Likes
Average of 2.2 Likes per day
2.5 days increased the Likes to 438 or 306 Likes.
Figure about
102 Likes per day since installation (actually more, but I'm dividing Likes by 3 days for simplicity's sake)
I should also note, that I have the time frame set to 3 seconds and not the default 7 seconds. I think this is something that you could play around with to figure out where the "sweet spot" is. I just set it at 3 and left it.
Traffic-wise, analytics doesn't show any noticeable increase in traffic. To be fair, CodSpot never says it will increase traffic. So, this is just an observation and not a judgement on the script.
The script works and works well. It does exactly what it's supposed to.
Is it worth $20? In my opinion, yes. If you are looking for an auto like script that works, this is it.
Want a disclaimer? I didn't pay $20 for it, it was given to me to review. This review is based solely on my observations and opinions. If it sucked, you guys know I would have said so, but it does exactly what it was designed to do. What more do you want?
/edit/ just refreshed my site again and it's up to 442. This is fun
/edit #2/ This is the original "Like" button I'm using on that site:
