So to sum up all of the replies is basically, Don't give up, start a new niche, use better keywords, wait longer... Right?
Well, what do you want?
It's like someone with a brick and mortar business turning up to a business networking breakfast and saying "Help, my business isn't making money. I've taken action, what now?!"
He'd be laughed out the building.
You've created a handful of tiny sites, added to reddit, created a fb page, put your link in your sig and mentioned 'seo', but not any keywords/rankings. You've then messed about with some ad placements and then decided you've done it all, taken action so it's time to go and get someone else to tell you what to do.
I'm sorry but that isn't how you run a business m'friend. If you want to be told what to do next go and get a job. Nothing wrong with working for someone else, not everyone is cut out to run their own business.
If you're serious about running your own business then start getting up every day at 6am, starting work at 7am, take 15 mins for lunch and finish at 10pm. Do that 7 days a week. Keep a daily To-Do, weekly to-do and monthly to-do. Every evening transfer weekly tasks to daily ready for the next day. Every sunday night transfer some monthly tasks to weekly.
Keep a journal of everything you're trying including your results so you have a detailed log of failures and don't repeat them.
Spend 5 hours a day studying and 5-6 hours a day of productive work(writing, building sites, building products, real work, not reading)
Study accounting and business. Find out how to run a real business and how to do your accounts. Learn how to create a business plan and make one.
Study copywriting.
Read through bhw and keep a 'methods + tips book'(pen + paper) -- Write down methods, have sections for various topics and write down useful information you find.
Use a contact resource managers of some sort. I use a wiki for this purpose. Keep track of everyone you talk to. Write down their contact details, important information about them, logs of chats. Network with people, build contacts.
Simple, but effective project management. Use your wiki for this. Keep track of your projects. Keep it simple.
RUN A REAL BUSINESS.
A handful of small web sites with a sig on a forum for traffic is not a business.
Create an offline business offering services. There's countless threads on here about offline businesses. You can do almost anything for companies. You just need to be better at it than they are.
Build communities, authority sites, membership sites. Online real estate. Real assets.
Study more about social and use your copywriting/psychology/human behavior knowledge you'll learn from copywriting books to make them work. You can't just write some shitty article, bookmark it and expect it to go viral. Some things just do not work with social. Most things don't work well with social in fact. A gaming article is never going to go viral on reddit and a self ip site is just a waste of time.
Buy advertising. Reinvest your offline profits and use your copywriting skills. Learn about media buys, ppc, ppv and every and any way to buy traffic. Test test test. If you're good at copywriting you'll do well with paid traffic. COpywriting/psychology/human behavior is KEY. 99.9% of marketers have zero clue about it.
Invest in offline advertising. Radio, tv, newspapers, magazines. Go to the stores and look through all the magazines. Look for niches, see what sells and what they're interested in. Email the magazine's advertising department and ask for demographics and advertising prices. Create products, advertising online based on demographics then advertise in the magazine.
Build email lists for your communities/products. Cross-sell stuff, push new products and maintain fresh/trustworthy lists.
Is that enough help for you? Follow that and you'll be successful. Do you know how the successful people solve problems? We don't create threads or ask people for help. We test stuff and learn from failures. FAILURE IS YOUR TEACHER. If you're afraid of failure and get depressed when you fail then you will never be successful. Fear of failure is like fear of the road to success. If you can't walk on the road you can't get to your destination.
