CREDITING TIPSCOOKIES - Properly set your cookies (most sites require that you set your cookies to accept all) and most suggest clearing them after EVERY offer for proper crediting.
POPUPS - Most sites will credit better if you allow popups on their site.
PAGE LOADING - Always make sure that the page fully loads before you move on to the next page or you close. Some users will wait an extra 10 seconds or so just to make sure.
DIRECTIONS - Some sites will spell out exactly how many pages you have to fill out or what message to look for to know that you have gone far enough for credit.
EASY FREEBIES - Some sites have 1-2 pages email and zip code offers. On these offers you will only need to input your email or zip and possibly fill out address info on 2nd page. The catch here is that many offers are sponsored by the same company. You are only allowed to fill out one offer per sponsor (per email - see EMAILS). Some sponsors are Generous Genie, Mega Promotion, and CPC.
EMAILS - I suggest setting up an email specifically for GPT's since you will get tons of SPAM. Extra emails are handy!! EASY FREEBIES go by email addresses. If you have extra email addresses that you don't mind SPAM on you can use those to do multiple offers from one sponsor. You can get free emails at Hotmail and GMail. Some sites have trouble with Yahoo.
BROWSER - Most sites are compatible with IE but there are some that work better with Firefox. Prizebook for example has admitted that Firefox users have an easier time getting credit.
MAKING EXTRA CASH TIPSREFERRALS - Referrals are a great bonus to the GPT's. The more referrals you have the more money you make. Some sites will pay for each referral and some give you a % based on offers they complete.
PREPAID CREDIT CARDS - Prepaid Credit Cards are the way to go if you decide to start doing the trial or credit card required offers. That way if you forget to cancel the product or subscription after the trial ends there is only a certain amount available on that credit card and you are not stuck with extra charges.
CONTESTS - Most sites will have monthly, weekly, and daily contests. You will get emails from your GPT sites - make sure you read them all and keep up on them. You can make easy money and prizes.
TIPS - EXTRAS
CONTESTS - Owners of GPT sites make money if you receive credit. Keeping that in mind if you have any issues getting credit just email the owners (usually have a support ticket area) and most have been very helpful in problems I have had and have gotten back to me very quickly. Never hesitate to contact them!!
HOW TO/TUTORIALS- Most sites have a 'how to' or 'tutorial' section. I highly suggest reading through them on each site. They will explain about payment, payouts, contests, common errors, etc...
BRRING.COM - This is a site that pays you to get calls! Once registered you are assigned a brring number. That number will call into your regular line but those who call that number will hear a 10 second ad before you pick up. You get paid for every ad heard/call received. YOUR REGULAR NUMBER WILL WORK AS NORMAL - NO ADS! Only those you give the brring # to will hear the ads. I use this number for my GPT's. I figure I might as well make money off of all the telemarketing I get!!
