Welcome to the Q&A Forum

Hi all, I'm currently considering implementing some overlays on a site. They're likely to be time-specific (so running only on certain hours and days), visitors will only see it once and content will also be slightly different based upon the region of the visitor (US, Non-US). They will be marketing-based messages tailored to the visitor based on where they are visiting from, I was thinking about putting the content of the overlay in an <iframe>and blocking it from being crawled/indexed by bots.<br /><br />Would this approach set-off any alarms with Google in terms of cloaking or any other nasty things? To clarify, they'll be as unobtrusive as possible to the visitor.<br /><br />Based on the above approach, bots will see that an iframe is being called, but with more or less no content - would this be a problem too?<br /><br />Another approach i thought about would be to dynamically serve different images based on the region...<br /><br />Lastly, assuming correct and safe implementation from a technical perspective, as a generality, have people seen better results from capturing exit traffic, timed overlays or when people first land?<br />Any advice appreciated!</p></iframe>
