Considering that you have a finite amount of time, passive income should make up a large part of your work. If you're serious about generating any semblance of income online, then passive income should be one of your sole goals and ambitions. Why? Wouldn't you prefer to do the work one time and get paid repeatedly as opposed to relying on your time to generate that income? Invest the time at the front-end so that you can reap the benefits on the back-end. This means putting in a bit of sweat equity and not getting paid today. Rather, you'll get paid somewhere down the road. And you'll continue getting paid whether you keep building that passive income stream or you stop.
I loved the landing page idea. This would be very effective in one case ONLY. If you are promoting a product or a an eBook this would work very fine OR increasing an Email list by offering something for FREE. You know in this life “Nothing is for FREE”. So you are giving your visitor for an example “A guide to how to install a blog template in wordpress or blogger” or “how to monetize your blog?” a FREE guide will drive this visitor to type his email and hit the subscribe button right away. But if the visitor a PayPal Button he just click the MAGIC X button on the top of his browser. Landing pages are very effective when you know how to use them.
I always add an HTML table of contents to posts to make sure they are long and structured. This has been a HUGE help for me (and my readers) and there are tons of benefits: better chance of getting “jump to links” in Google (see below), increased average time on page, decreased bounce rates, and it makes it easier for readers to navigate through your content.
