1. I think the effectiveness depends on the niche. It is a tough question to answer. It is best to use each of the methods and if you can segment out when you do each of the linking methods you might be able to get a clue about which methods work best for your niche. I will add that blog comments do add a very positive component – more diversity in the linking domains. Sure, they are no follow backlinks but there might not be a better way to get links from hundreds of different domains.

2. How do you go about looking for expired domains for your PBN? I’ve tried Jon Haver’s system but the searching part takes quite a bit of time with not too much to show. I think I’ve tried doing it like for a couple of hours all I found was 2 or 3 domains that had PA of around mid 20s or so. Nothing great.Wondering if you’ve found a more efficient way.
This isn’t to scare you off. I simply want you to know that this guide is going to focus solely on ways to make real, sustainable extra income online. Not just a few bucks.

And while it will take time to build up a big-enough audience to attract advertisers and other ways to make extra income from your podcast, the opportunity is there. John Lee Dumas interviews entrepreneurs seven days a week for his podcast Entrepreneur on Fire and now makes more than $200,000 a month from it. In fact, John publishes all his income online and showed that he’s made almost $13 million since launching in 2012.
I absolutely see the value in affiliate sales (and Pay Flynn is one of the masters at doing this authentically and openly), but I got really turned off it when I saw a lot of bloggers I read and respect writing junky “How to set up a blog” posts that didn’t seem relevant to their audiences purely so that the could get the sweet Bluehost commissions in.
The link building was a critical step.  It was time consuming.  I followed the standard plan you see in several other blogs (like Niche Pursuits) with tiered linking structures. In general, you could categorize the links as social profiles, web 2.0 free blogs, and article directories.  I also purchased a few fiverr gigs to point to the first tier of links, not the niche site (the money site).

Who can tell me if “link masking or cloaking” is a violation of the Google TOS? I think it is and I see dozens of affiliate sites doing it. I also see quite a few sites not using “nofollow” on their affiliate links. Unless your masked link says something like “I bought product X used in this review at Amazon.com” it would be a violation. I think if reported, you’d be in for a manual spam action against your site. Thoughts?
Some advertisers offer multi-tier programs that distribute commission into a hierarchical referral network of sign-ups and sub-partners. In practical terms, publisher "A" signs up to the program with an advertiser and gets rewarded for the agreed activity conducted by a referred visitor. If publisher "A" attracts publishers "B" and "C" to sign up for the same program using his sign-up code, all future activities performed by publishers "B" and "C" will result in additional commission (at a lower rate) for publisher "A".

If you don’t mind doing other people’s chores, then TaskRabbit is a great option for making money online. Earn extra income by walking your neighbor’s dog or mowing Mr. Smith’s lawn.

You may decide to create free videos as extra content for your blog, and not sell them at all. If this is the case then you can still make money from these videos by selling advertising space on them (in the same way as discussed for monetizing podcasts). Once you have high volumes of traffic visiting your blog, and watching your videos, you can charge businesses to advertise at the beginning of your videos. Use website’s like Izea to help you connect with companies willing to pay to advertise on your blog.
Prior to that group, they had an online community for teachers looking for lesson plans. That probably sounds pretty random, but it's crazy the type of communities you can build and rally people around. If it's something that you're passionate about yourself and you want to connect with others that have that same passion, then an online community is something you should definitely consider.

Forms of new media have also diversified how companies, brands, and ad networks serve ads to visitors. For instance, YouTube allows video-makers to embed advertisements through Google's affiliate network.[22][23] New developments have made it more difficult for unscrupulous affiliates to make money.
