1. PPC Advertising Networks
Google
AdSense is the most popular option under this category, but there are
also others. Basically you need to sign up with the network and paste
some code snippets on your website. The network will then serve
contextual ads (either text or images) relevant to your website, and you
will earn a certain amount of money for every click.
The
profitability of PPC advertising depends on the general traffic levels
of the website and, most importantly, on the click-through rate (CTR)
and cost per click (CPC). The CTR depends on the design of the website.
Ads placed abode the fold or blended with content, for instance, tend to
get higher CTRs. The CPC, on the other hand, depends on the nice of the
website. Mortgages, financial products and college education are
examples of profitable niches (clicks worth a couple of dollars are not
rare), while tech-related topics tend to receive a smaller CPC
(sometimes as low as a couple of cents per click).
The
source of the traffic can also affect the overall CTR rate. Organic
traffic (the one that comes from search engines) tends to perform well
because these visitors were already looking for something, and they tend
to click on ads more often. Social media traffic, on the other hand,
presents terribly low CTRs because these visitors are tech-savvy and
they just ignore ads.
