are ptc sites worth it? yes

[preech07]

in my opinion they are as long as your using 2 or more you don't earn much but it all adds up i have around $11 in my alertpay account from ptc sites and will leave it to grow until just before christmas and then can get a good christmas present from that money

You don't necessarily need 2 or more- 1 quality site can beat 10 crappy ones. PTC can certainly be worth it for certain niches and certain types of sites. For others though, it might not be the best option. Webmasters should experiment and see what works best for their particular sites.

Yeah, you don't need 2 or more. The way to make good money on PTC sites is referrals. Referral earnings are where the big money is at. Whether you buy them, or refer them yourself, either way works.
