20 Content Locking Ideas
Entertainment and Video Sites
Everybody  wants to see the latest videos and viral clips online. Throw up a nice  video hosting website with a unique template and find some exclusive  legal content. Gain traffic via social media or SEO and lock the videos  with your gateway.
Instructional Videos 
Play the guitar?  Good at computer games? Make some instructional videos on "how to" and  post them on YouTube. Only post the first video and then link back to  the rest of the video on your site. Content lock the follow up videos.
Software Downloads
Either  acquire or create some software that user will want to download. Make a  site explaining all the benefits etc but lock the download link with a  CPA gateway.
Templates
If you can make templates for  Wordpress etc then make some nice ones. List them on template sites but  lock the download file with a content lock. Also you can include the  content lock within the code of the template so when the downloaded  installs it, it will have your lock on the page.
File Conversions
If  you can program or have someone who can, why not make a site that will  offer users conversions from file to file. They input the file and click  the convert button where they are taken to another screen to fill out a  CPA gateway to download their converted file.
Free Trials
Say  for example you own a gaming website or a product that users will sign  up for. Offer them a free trial and then in return for the full version  they must fill out some incentive offers. Maybe make them do one a month  in return for the full product.
Help and Advice
Have an  expert field? For example can you program? Make a support ticket system  or forum where by you offer free support but they must first complete a  gateway to submit the ticket or thread.
Memberships
I was  the first ever to do this, but if you have a website or forum whereby  you can offer an exclusive membership package for example VIP with extra  features. You will get far much more activity and earnings if you offer  it to them for free in exchange for filling out some offers on a  gateway styled like your website/forum.
URL Shortener
If  you can acquire a URL shortener or a similar script, offer it for free  but on the point of the user getting the result they want, lock it with a  gateway.
Write an eBook
It doesn't matter what the niche  is but you can also build a list of it. Write a book about something you  enjoy for example gaming. Post it on a website with a opt in page and  then set a password for the book that a user will have to complete a  content locking gateway to see. You can choose which offers to show  depending on your books niche.
Hot Trends
Find out whats  trending and write your own variation of the news or get the video etc  everyone wants to see. Place it on a unique website and lock the "View  Video" link.
Cheats and Codes
There is a huge audience and  big traffic in gaming online. Make a site dedicated to game cheats and  codes and describe them as much as possible. Make the user want the  cheat that bad that they will be willing to convert an offer on your  gateway.
Guides and Tutorials
Write some guides or  tutorials and place them on a website. Place each chapter on a separate  page. Now give the user a few chapters free until they are hooked in and  then lock the next chapters with your gateway.
YouTube
People  search for EVERYTHING on YouTube, so if it's something that people  want, it's something you can lock. Create a video with keywords related  to the search subject and then place a link in the footer to the answer,  locked!
GPT
Get Paid To sites are great for earning with  content locking. Users are rewarded with points/prizes in exchange for  filling out incentive gateways.
Torrents
Download the  latest videos and music and convert them into torrents. Then zip them  but add a password to the file. Then zip the two files with another file  explaining you can get the password at this URL. Place the password on  the URL but with a content locker on top.
Support
If you  have a site with regular members, offer free support to them via your  support tab. In order for them to see the support reply they must first  fill out a CPA gateway.
Graphics and Stock images
Do you  graphic design? Offer free graphics on forums in exchange for customers  filling out incentive CPA offers on your gateway. Alternatively throw up  a site with some icon sets or free stock graphics etc, give them a few  free but content lock the download button for the full sets on your  site.
Adult/Porn
Always check that the offers can be used  for adult traffic. Build or buy a porn site with traffic and lock some  of the more exclusive videos with a gateway. Also you can offer full  membership in return for them filling out offers.
Donations
A  lot of sites have donation tabs on their pages to ask users to donate  for their work. Although i think its tacky, instead why not have a  donations tab where by a user can donate by filling out and incentive  offer. This way they don't even need to spend money!
Buy Websites
One  of the best ways to get started in content locking is to buy bargain  websites that aren't being monetized for content locking. You can easily  find sites on Flippa and other popular forums etc that are already  receiving traffic and haven't been using CPA gateways. Just because  another person is selling a site it doesn't mean you can't earn from it.  Most people don't even think about gateways. Be on the look out for  sites you can add a gateway to at some point in the users transactions  and bank!
Optimise and Test everything!
Like i explained  in the intro the beauty of AdWorkMedia is that they have various tools  to optimise and test your gateway. Make the gateway really fit in with  your site as if it was a part of it. Test different copies, skins and  offers.
