Anything viral, such as social media marketing is going to be very helpful. I'm assuming your site is similar to 9Gag. A lot of my friends on Facebook post 9Gag photos and videos all over Facebook. What you want to do when you do Facebook marketing is have people share what you post. Create a fan page and have some close friends share your site and/or photos on their pages.
I think that the better way to promote a website or product are Social Media like Facebook,Google +,Twitter,with youtube video etc
make a facebook fanpage and post 1 daily funny picture with a link to your site for more! Use a $50 facebook ad credit to promote the fan page. Wouldn't hurt to set up a twitter account either.
Make sure you add some viral plugins to make sure your site goes crazy on youtube and twitter. You can also have your subsribers opt-in to your mailing list so that you can keep them updated about new developments and other funny things.
Lol everyones saying the exact same thing lol. Viral marketing is your best bet definitely and you want to have an extensive campaign on all social media platforms (not just FB). Also you need to realise that the whole comedy pics etc is pretty competitive so you're going to need to build lots and lots of backlinks through - guest posting, forums (DP for starters its not even in your sig link), paid advertising if you have the budget, articles if you have to and then just keep adding content
Basically, it comes down to two things: 1. Give people something worth talking about. 2. Make it easy for them to do so. Assuming that the images on your site are down right hilarious, I would suggest one thing: allow people to directly link to your images. Many sites want to save bandwidth and basically force people to upload the picture themselves somewhere if they want to post it (most people won't bother). This is the wrong approach. Let them directly link your images so that people can easily share them with everyone. If you want, you can have a little watermark on each picture with your logo or website so that the traffic gets sent your way.
This is also a very good idea, just make sure that you don't jump right in to promoting your site. Spend some time on the board first as a normal poster, and try to be helpful overall.
As some people already mentioned, I would also suggest stumbleupon because as I have seen, the humor seeking audience is quite big there. You can go either way paid or free, both should work well.
I thing that the best will be advertise on forums related with your websites by a topic. Start for this form of advert.
I think that one of the best way to promote your website is to post photos,videos and other stuffs which link to your site to Facebook, Twitter and Youtube. I think these 3 are very popular to people of different ages.
I think Facebook is the best option. Easy to do, and easier for people to share, and in turn grow your audience.
Yes, that's right. In Poland is a kwejk.pl - web portal, which reached a amazing popularity only by a Facebook! Peple share with friends a new photos from kwejk on their wall and it works base on a loop
Social networks is the best place to promote your website. If your website has a really high-quality content (corresponding to the idea), then the rumors spread quickly.
So the conclusions are: 1. Jump in related forums or blogs, leave comments that add value to the readers (which would be humor and funny related things), place siggy or link back to the website. 2. Build a hilarious fanpage about your site and post something good to urge people to share your post 3. Keep posting a good content 4. Above all, youtube, twitter, facebook, and digg are great to begin with.
