My customer want me to to promote their new product by using google adwords. However, this site is based entirely in Flash and when I checked the cached page, the result is that Google can't see the content anymore.
From my experience good CTR can result to low CPC, but this was for content rich site not flash one.
What I need to know is that, Is Flash content will make Google think it irrelevance and cause very high CPC? and If I receive Good CTR will CPC can be lower.
So I think the best way for excellence conclusion is to ask for you guys who have experienced adwords for Flash.
Thank you in advance
That's what I told a potential new client just last week. To me, it only makes sense that's the case. I also told him a HTML site would be indexed more easily by the search engines. Although he is emotionally tied to his year-old Flash site, I think he'll do it.
Your case may be different. I certainly don't recommend changing every Flash site to HTML as there may be a valid reason it's using Flash (not in my client's case). But apart from the above concerns, I don't see any problems using Adwords to advertise a Flash site. If the client insists on Flash, you could try asking Google for a manual review in hopes of reducing CPC.
