Advice needed on PPC and native content advertising.

Hello Warriors,

I was wondering if I can got some advise on PPC networks and native advertising networks for advertisers. I am running a nice little sub-niche in the romance/dating/PUA arena (non-pornographic) and I want to get a bigger reach using such networks. I am still small time so needless to say I want to go big.

Only this year did I start taking my online business seriously and start paying for traffic. As a result my sales went up and I saw a big spike. Here is what I am doing so far:

PPC Networks:
1) POF - really liking the results for my 110x80 ads but my 310x110 banner are awful
2) BuySellAds - ran a 300x250 ad for 7k impressions with awful results (I'm sure I need to redo my ad)
3) exoclick - made this mistake and ran it on adult category and saw a test budget of $200 fly out the window in 45 minutes (a whole lot of dudes seeing porn during the day). Frankly I was surprised.
4) 7 Search - any warriors using them with great results?
5) Max Bounty - wondering if they really deliver solid traffic?

Besides MaxBounty and 7 Search; am I missing any other PPC networks that would deliver great results?

Native Ad Adverting is proving more tricky and there are so many native adverting platforms to choose from, here are a few that I know of:

Native Ad adverting:
1) Hexagram - I'm using them currently with so-so results. The biggest drawback is that it's NOT self serve. I have to email the creative to them and they do it for me...dumb in my opinion.
2) Taboola - I need $2,000 monthly budget
3) AdBlad - won't use them because sales rep bait & switched me after I funded the account.
4) Outbrain - they deemed my site leaning too much on the adult spectrum and turned me down

Besides the 4 above - can any warriors using native ad adverting suggest others that would work great for the site I am promoting (romance/dating/PUA)?

Thanks in advance really appreciate the tips you can offer.
