Every day you can earn up to 270 points. Most weekdays there's generally one or two extra ways to earn another 10-30 (maybe upwards of 50) points. You'll see usually four emails a month (once a week) with links to click and you can earn another 50 points that way - the last email I saw come through a few days ago was about otters. Click a link to see otter videos (you don't have to watch them), click a link to see otter pictures, a link for something else about otters and a 1 question quiz (keep picking the the possible answer out of the 4 given to earn points). There is also a Streak Bonus you can earn for logging in on a constant daily basis to earn extra points.

You need to earn 500 points a month to obtain a Level 2 status - this brings down the overall cost for rewards by a little (maybe 10-15%).

There are a good handful of different rewards. I tend to save up for 5,250 points and redeem a $5 Amazon gift card - I do this about every 3 weeks and after a year I've built up $90-100 on my Amazon account in gift cards. For me that's a free $100 or so to buy Christmas presents with.

If you just did the minimum daily 270 points (here's the breakdown):
Daily Poll - 10 points
Daily Quiz - 10 points
PC searches using Bing - 150 points (5 points per search)
Mobile searching using Bing - 100 points (5 points per search)
You can earn 1890 points a week (7 days).

If you factor in the 4 - 50 point emails a month, that's 200 points.
If you factor in the Streak Bonus and you don't miss a log in for the first month, you earn an extra:
extra 45 points - Day 3
extra 75 points - Day 8
extra 75 points - Day 13
extra 105 points - Day 20
extra 105 points - Day 27
(every 7 days after that I believe you earn 150 points - I think......)
That's an extra 405 points in a month.
Then some days (generally weekdays) there are a few other links/activities to click on to obtain other points from 10 to 50 and it's easy to say you can generally, easily earn an extra 50 points a week.
Also, if you utilize MS Edge while searching in Bing, that is an extra 20 points a day (600 extra points a month)

In all, you should be able to easily earn in the first month:
7,560 (from 1890 a week - 7 days)
405 if you get a 28 day login Streak going
200 extra (at least 50 a week for extra added links/activities)
600 points using MS Edge while searching in Bing
8,765 points in the first month - that'll will get you a free Xbox Live Gold for a month

You can also earn points if you shop through the MS Store online - I think it's a point a dollar. I've never purchased anything from the store, but I figure I'd mention it since it is an optional way to earn points...if you want to buy stuff.

Just thought I'd share. I do this every day, usually in the morning or sometimes during my lunch break and it takes me roughly 5 minutes - it may take a little longer for anyone new to it, but once you learn how it all works, about 5 minutes a day during a downtime period while you're probably at the PC or on your phone anyway....might as well earn points and get yourself something in return.
