whitenight,
why do you continue to beat yourself up over this? If people do not want to read and do their own research, and just come here and post their theories, there is little you can do.
I watch all of these replies and I get a headache just reading most of them. Part of me wants to reply to them but I know that they will not listen. Do you really blame them? When everyone thinks they are an expert and starts posting their crazy theories and opinions, its hard to know who actually knows what they are talking about.
I will try to explain as simple as possible for all the folks who are confused about caffeine.
There is a lot more to caffeine, but this is for the people who are lost and/or confused.
What is google caffeine?
It's a google update. Google has made some changes.
Will my SERP's be different on caffeine?
Most likely you will see a slight difference in SERP's for most if not all of your search phrases. Google uses over 200 factors to rank a website, when they make even a small change to their system, it has a trickle down effect.
When will it be released?
Google announced it has released caffeine to 1 datacenter so roughly 10-20% of google users will see caffeine, the rest will see regular non-updated google.
How do I know if I am seeing google caffeine or regular non-updated google?
Well, since most people will still be seeing regular google, you will need to do the same search on different computers until you see some difference. It is important to know how to search so that you do not mistakenly see personalized results. There are free proxies that are available to use. Picture a proxy like internet teleportation, you can have a computer from somewhere else retrieve web pages for you. Make sure the proxies you use are in the same country as you. Run your search query on at least 20 different proxies, if you find several that return slightly different SERPs, congratulations, you have found caffeine.
Proxies sound too complicated, is there anywhere else I can get this information?
Absolutely. Just call all your family and friends and have them do the search for you. Just tell them its a cool google experiment.
As of right now, as far as I can tell, caffeine is not available anywhere. Not in the US anyway as all the proxies with caffeine I have been tracking for the last 3 months do not show these updates at the moment.
I hope this helps someone.
