Facebook is overcrowded with online job ads. Where else can I advertise?

There are literally thousands of places to advertise , seeing as I'm still relatively new to this internet  marketing  idea, I don't have as much experience as  I would like to have, but  i will  provides us with all the info we need. Most of the following examples are free, I would start with them, and then move onto paid platforms, once you've seen what works best for you. Some examples include:Twitter; Google+; LinkedIn; Newspapers & magazine; School journals & bulletins; Flyers & Poster; Whatsapp groups; BlackBerry messenger groups; Schools & Universities 2go; Instagram; Palmchat; Personal Blogs etc. Facebook is cluttered, it is true in my opinion, the best place to advertise for the largest on-line presence of the people. My experience is that I am advertising the groups had very poor results because in those groups predominately profiles that advertise, but not looking for an opportunity. Here and there, after a review of your blog is happening in this way. Paid fb campaign is for me a better way. For a few dollars to get a few hundred hits on the blog, but occur and inclusion. Not going fast and easy but still works. I hope that my little experience on advertising contributed to answering the question. Greeting!
The best is to start a Blogger blog and website. It is free for all GMAIL users. 1. On the website create a mini-shop for you with photos and links to TripleClicks. You can create more than one mini-shop. In this case it would be ideal to create a main site (your Head Office site) to make it easier to promote all sites in one go. 2. Use your blog to promote new features on SFI and TripleClicks with invites under banners. 3. Shorten your two (or more) Blogger URLs with goo.gl for ease of use. 4. Promote both your blog and your website(s) short links on Facebook and/or Twitter and/or any other social media site you are using. The best is open end advertisements that ends with "Inbox me for details." in stead of a link. If you get a message or a comment asking for details then MESSAGE the details to them. Remember to use the short links to make it easier, especially with Twitter where space is at essence. 5. Join Traffic Exchanges and different mailer programs (safelists, viral mailers, etc.) and promote your sites. If you can, upgrade to get free credits every month to automatically promote your sites. There are so many other places to advertise, I use Twitter, Traffic Swarm, EasiHits4U, Business Worls List and many more besides. There are Safelists that you can us as well, but be prepared to get a lot of Emails in return if you go down this route. 
The Traffic Exchanges are a great way to go if you have no spare budget as all you have to do is to browse the other sites on the Traffic Exchange to earn points for your sites to be viewed. I use Traffic Swarm a lot and EasiHits4U, just put your Gateway URL on the website under your name and then surf the websites that come up to get points for your websites. 
This only takes some of your time and none of your money.
