Oh i did not notice the new system has taken place. Anyway i couldnt reply on the old system, so i have to reply here, i hope you dont mind.
First off, thanks to you and rand for answering my question. and I have couple of responds for the answers, to clarify many things
#1A. The problem for LINK Sharing on twitter can be easily solved, i just need to put the right URL for tweeting button (and perhaps even for share button / email to friend button). For manual sharing and email , we can easily create a LINKTO field inside the website, so that people can copy the right link (although admittedly if they take the link from their Browsers Address, it could lead to the potential lose of backlink to that page. On facebook however, is another can full of worms, because their 'like' features do not allow the developer to post different URL, it will autodetect current URL (however i will see to this if there is any work around it myself by diving into the FBXML)
#1B. Okay i dont have any problem with this too, because all content inside the flash content is a fully dynamic content, A.K.A the swf the browser load is totally empty, void of any picture, text, design, layout, etc . Everything including the layout is loaded dynamically on the fly. And i am so certain that no search engine can ever crawl to this. so i wont have any duplicate content
#1C. Indeed, it is ideal. My company is a web development company that creates its own Engine (with easy to use CMS), last year our engine can only output the Flash Version, this year we can output both the Flash Version and HTML Version, and why we stick to the normal XHTML 1.0 (with css 2.1) and not HTML 5.0 (with css 3.0) because not all mobile browser can handle HTML 5.0 (hell even the firefox vs chrome vs opera vs ie9 all have different kind of unsupported feature on css3), which defeat the purpose of us having the engine to output the HTML Version, which is to allow our client's visitor to be able to open their site from their phone (not exclusive to smart phone)
#2 Glad to know that it is fine
#3 The AJAX Crawling uses HTML Snapshot which is what we used exactly (but ours is much more advanced, complicated, because the original version is a Flash Version which has absolutely NO HTML, so snapshoting the EXACT page into a HTML Version, and dynamically update the HTML Version when the Content inside the Flash Version changes is so damn complicated, but hey we have finished it , and it works perfectly)
for example the FLASH URL
http://atlantagenset.com/#/item-category/genset-bekas.html
has a PERFECT HTML Snapshot in this URL
http://atlantagenset.com/item-category/genset-bekas.html
I only have 1 Follow up question, to seal my original question as solved
1. My follow up question is a repeat my original and most dire question, CAN i implement the redirect when google bot / yahoo bot / bing bot go to my root homepage to the HTML Version homepage without penalizing my SEO Standing (without the #1A, #1B, #1C concerns) ?? I am concerned with Alan Mosley's answer, that i might get flagged. I certainly dont want to show different content to the Crawler then what i show to the Visitors, Content wise there is ABSOLUTELY no changes, no masking whatsoever, it is only to make the dynamic Content inside the Flash Version understandable for Crawler (Like what Google itself suggesting in http://code.google.com/web/ajaxcrawling/ )
this redirect is specific to when google bot / yahoo bot / bing bot opened the http://atlantagenset.com (because any other pages inside this URL IS a HTML Version, only the http://atlantagenset.com contain the FLASH Version)
Example when google bot crawl this http://atlantagenset.com page
My PHP Script detected this, and redirect the google bot to http://atlantagenset.com/menu/home.html
the redirect php script i used is
header('Location: ' . $TargetURL);
Remember my redirect scenario is only for when google bot / yahoo bot / bing bot crawled the http://atlantagenset.com ONLY , and not any other page such as http://atlantagenset.com/menu/about-us.html , etc
Before and after, thanks a lot for the time invested in answering my question , i am so grateful, especially when you mentioned the "Social Networking" bits , it raised more question that is not related to the original answer, but i do have a follow up question about it, BUT should i not be questioning in here (since i already used both of my questions credit) then i dont really mind to ask them next month
The Follow up question about Social Networking bits
So are you saying that Google / Yahoo / Bing do crawl the facebook , tweeter page? even though the tweeter page uses the Short URL Version of the original URL?
Or you are only saying that it will help to make the site much more popular hence it will generate more click to our site hence making the Page Rank of that page raised a lot higher?
Cheers and God Bless,
