Earning money online comes with a stigma attached that it's all scams and pyramid schemes. There are many good and reputable sites available too though.

I have personally been caught out twice. A site called Can't Beat Free disappeared leaving people owed money and gift cards. Another site called Rewarding Ways waits til people reach payout level and accuses them of having several accounts or using a proxy IP address. 

Sites I can verify that pay out:

Swagbucks

Gifthulk

Zoombucks

Irazoo

Global test market

Onepoll

Neobux

Clixsense

Inbox Pounds

Opinion Outpost

Pinecone

Panelbase

Roamler

Another site of the PTC genre which I can vouch for as being reputable is Zoombucks.

The site, in my opinion, could be considered as a smaller version of Swagbucks or Gifthulk.  The various offer walls are all there, similar surveys and there's various competitions to boost your ZB points.

Offer Walls - Not much you won't find elsewhere but I usually get some additional paid to watch videos on the Super Rewards and Volume 11 walls that I don't get on Swagbucks/Gifthulk. There's also a Daily Offer contest (bonus) for people completing an above average for that day number of offers.

Daily - At the bottom of the Offers Wall there's a CAPTCHA which you gain 1ZB from daily.

Competitions - "Pick a number" for free entry to win a small prize.

Promo Codes - They tend to have a regular supply of code posted on their Facebook page.

Cashout is $5 and is paid by Paypal.

I've previously mentioned the Money Saving Expert forums and the valuable tips and challenges available there. Would like to drop a mention to a somewhat smaller but equally valuable resource - The Money Shed.

Users review the various PTC, survey and other money making sites.

There's also an interesting section for Money Saving tips

Another site which I can now recommend is Clixsense.

Having used other PTC/survey sites, I can see certain similarities but the one notable difference is the income. From what I can see only Neobux compares to Clixsense in the compensation for completing the various tasks, surveys, clicks and special offers.

Tasks - These are the same Crowdflower tasks you see on many sites.  The Casino/Investment tasks pay $0.07 per task.  Investment tasks usually appear between 8-10pm UK time. The Casino tasks tend to appear after midnight.

Special Offers - Token Ads (lots of videos), Trial Pay, RadiumOne, Peanut Labs, Super Rewards, SupersonicAds and Matomy all have offer walls on the site.  These generally pay much better than Swagbucks and the like - again, only Neobux compares.

Paid to Click - less ads than Neobux, but a much higher amount of $0.01 ads.

Surveys - Toluna ($0.67 per survey) and Samplicious both have survey walls.

Each day there is a Daily Checklist bonus where you earn a further 5% of your earnings.  If you're earning a good amount on this site, its worth upgrading to a premium account ($17), where your bonus increases to 12% with some other added bonuses on referrals, increased number of adverts etc... To break even with this, you need to earn $0.05 average daily from your checklist bonus (easy).

Another of the other interesting challenges to come from the Money Saving Expert forum users is the £2014 in 2014 challenge.

Basically that's earn £2014 from any source outwith your normal employment/income.  

That can come from many ways - overtime/additional work, Ebay, Paid to Click or survey websites, cashback sites....wherever.
