Most AVS systems require the user to pay for a membership but some offer free memberships as well.  The same password opens thousands of participating adult sites.

If you are a webmaster, the choice is much more difficult.  Its usually best to pick one or two AVS's to use on your site.  Each one has their advantages.  To help you, we've listed some key points of the ones we've worked with directly and recommend.

PAYS $25
for free referral

• System is free so it attracts a lot of referrals.
• Pay on time
• Quick staff setup and review
• Curtain page easy to implement with just one line of code.  Or no AVS intro needed!
• It is a rather new AVS so not many people have the passwords yet, so your referral total ($) will be increased.

• Able to create child entry tracking points!
• Able to sign-up new sites in real time.
• Multiple intro pages and stat features.
• Pay $25 per referral.

• Site declairs itself to be an adult billing system and not a true AVS, but billing acts 100% the same.  Only problem with this approach is you can advertise their site list on your logon page.
• Lightly strict with site acceptance, although they do tell you what's wrong and how to fix it.

Hint: unlike other AVS's there is a way to sign up users without using the AVS pop-up and logon screens.  After your setup goto sites -> referral code and you'll see a user signup link.  This should be very useful for those who want to make one-click signup links and their own systems.  Great feature.  Also, take advantage of the site's ability to use multiple links.  You can track where your visitors sign up and why.  If you need a host that supports this AVS visit WEBster.

Hint: after you make your fifth sale they offer you a free domain name registration of your choice.  A default control panel comes with their domain, which you can use.  But if you want total control of your free domain name switch your domain's DNS entries at the registry to your website host.  If you need a host that supports this visit WEBster, they handle these configurations all the time.

1. Building traffic: The most accessed web page on an AVS site is your curtain page (where customers enter their password and/or create a password.  New customers as well as internet users coming in from the thousands of participating sites will see this page on every visit.  If you are a member of a link list or a banner exchange, its a good idea to include a banner or two on the bottom of this page.  But remember, this is the doorway to your site so it must be presentable.  If your going to use a banner keep it out of the way and don't use more than one or two or bye-bye users.
2. Get listed: Each AVS service has a search engine which may or may not list your site.  Being listed is a good thing and will only lead to exposure for your site.  Make sure to follow  your AVS's rules to get listed.  Some require minimum pictures, etc.  If you are worried about visitors taking up bandwidth, well, your losing before you begin.
3. Style matching: Each AVS's welcome screen has a certain style or flair to it.  Since visitors jump from your curtain pages to the AVS screen back to your content pages, it is important for you to try and match the color scheme of the AVS screens.  This makes your sites look more professional in relation to the AVS.
4. Teasers: don't put all your content on the inside of your site.  The consumer needs to see what he is buying.  Your outside should look well programmed.
5. Diversify: Sign up for several AVS systems and test them out.  You will find that one will not produce as well as others for your site.
