I’m very newbie​ in this field, even I haven’t my website/blog pages. Its takes some time to build my website. With this article, I get some knowledge how to start. But I have question that if I want to start this from the social media like Facebook. Then what we should do first. Should we make a page relevant to niche ? And is social media is correct way to start or we should first make our own website/ blog pages?
The topic you choose must have enough depth that you can create a lot of content for it. This is important for building an authoritative site, for search engine optimization, and most importantly, for the end user. If you don't have enough content about a topic, you're not going to be taken very seriously as an authority on the topic and it's unlikely you can convince someone to make a purchase from you. 
File-Sharing: Web sites that host directories of music, movies, games and other software. Users upload content to file-hosting sites and then post descriptions of the material and their download links on directory sites. Uploaders are paid by the file-hosting sites based on the number of times their files are downloaded. The file-hosting sites sell premium download access to the files to the general public. The websites that host the directory services sell advertising and do not host the files themselves.
Amazon Associates — Amazon sells millions of products (books, music, electronics, toys, and more) that fit into virtually any niche, so its affiliate marketing program is a natural choice for almost anyone. Comparatively speaking, its payouts are generous, too: They vary based on product type and sales volume, but commission rates start at 4 percent and can reach up to 15 percent for specific product lines. However, note that Amazon’s program is now illegal in several states (although there are some work-arounds).
Hi. I am a UK resident. I have been trying to find out advice about whether you should register a company for payments through affiliate marketing and if so is it better to set up a as a sole trader or limited company (or equivalent in US). Please could you advise as I can't seem to find out anything about this but when you complete affiliate network profiles they ask for tax details and company names etc. Many thanks
Affiliate marketing overlaps with other Internet marketing methods to some degree, because affiliates often use regular advertising methods. Those methods include organic search engine optimization (SEO), paid search engine marketing (PPC – Pay Per Click), e-mail marketing, content marketing, and (in some sense) display advertising. On the other hand, affiliates sometimes use less orthodox techniques, such as publishing reviews of products or services offered by a partner.[citation needed]
