How would I have a landing page show up first that asks them to choose whether they are above 20 or under 20, then when they click "above 20" it has them go to the mobile site?

...also once they click "above 20", when they ever revisit the site in the future the "age verification" landing page does not show up.

Thank you to everyone on WF for all the great information, help, support, and kindness you have all shared!

Why would they need to be above 20 and how would you prevent teenagers or pre-teens from simply clicking that they are above 20? How would you test whether the people saying they were above 20 pretty much actually were?

The site is for a "smoking" site so we want to make try to make only adults visit it.

Use a pop-up that asks the question, then you'd have to drop a cookie to prevent re-occurrence.

Start here.

you could use a cookie...

have the landing page check for the presence of a cookie with the correct value when the user lands on the page

if the cookie is correct value and present dont show age verification and perhaps redirect the visitor to the correct page...

if the cookie is not present or the correct value then show the verification page

use the age verification as a form... on submit of the correct age it stores that value as a cookie and redirects to the main content providing the age is correct

hope that makes sense

obviously we all know age verification isnt exactly the hardest thing to bypass so to cover yourself ensure you have something like a checkbox for terms and conditions...

you could also use something like a facebook login... if i am not mistaken you could in theory collect the persons age from that... at least that would be a little more accurate and its a lot more time consuming to go and create a brand new profile with the correct age as once you set it in facebook you cant change it...

@BENQ

personally i would use php to do the writing and reading of the cookie since it is possible your mobile user may not have javascript enabled on their phone... additionally pop ups are not something you should use for mobile web as that goes against mobile best practices...

this link should help you OP

Thanks guys. Do you know where I could possibly get a premade script that I could add to the landing page so that when people visit mysite.com, they bypass the landing page and go directly to the mobile site...?

this may be a good start...
Jquery Version
JavaScript - Jquery Age Block | CodeCanyon

PHP Version
http://codecanyon.net/item/age-verif...or=thinkaholic

there are other script on Codecanyon but these seemed to do everything you where looking for... if you are using WordPress there are WP scripts too...

FYI this is NOT an affiliate link
