You will not be successful at affiliate marketing,  if you are just thinking about how many sales you will make.

Products/Offers you promote must align with what your target market wants in order to get sales/commissions.

Must be committed to making this business work

Choose a domain name that relates to the niche you’ve chosen for SEO efforts and for consumers to remember the name of your site more easily.

Use search tools at domain name registrars GoDaddy.com and/or Namecheap.com

Select a quality Web host, such as HostGator.com or BlueHost.com, to host your site.

A quality Web host is one with good uptime of your site, good customer support, and good reviews.

Decide on how you will build your site – HTML (Hypertext Markup Language), WordPress, your Web hosting provider’s Web building software, etc.

Research several affiliate platforms to find the one(s) you will use in your affiliate marketing efforts and to find the products you will promote.

Three main affiliate platforms are JVZoo.com, ClickBank.com, ShareASale.com.

All three platforms offer different products from different categories; JVZoo offers digital products, ClickBank offers digital and physical products, ShareASale offers physical products.

All three platforms require registration before use and promotion

Use the drop-down menus in each platform to narrow down the category and subcategory that matches or closely matches your preferred niche.

Consider various stats such as commission amount or percentage,  to find the best product or products for you to promote and profit from.

Apply the various filters available to find the perfect offer(s) on each platform to promote. pan

There are three main types of content to provide on your site/blog to convince people that an offer is worth their purchase through your link 

Use a combination of text, audio, and photos/videos to show people what a product offer is like and why they should purchase it.

Placing your affiliate link inside of your product review is a good way to get people to use your link to purchase.

Depending on the size of the review, you can use your affiliate link between 1-3 times, with it definitely going at the end of the review at least.

Utilize banner ads and sidebars on your blog to promote relevant affiliate offers

Providing extra bonuses differentiates your offer from other affiliates promoting the same product.

Consider adding ebooks, reports, videos, Webinars, software programs, etc. as bonuses.  

Either create your bonuses, use outsourcers to create them, and/or use PLR all or in part to create them.

Try to make the bonuses relevant to the main product offer .

Always look to build your list, even in affiliate marketing.

It takes an average seven contacts for most people to buy anything online

Use opt-in boxes on your site/blog, including review pages, etc., to get people to subscribe to your list.

If you provide quality bonuses during affiliate commissions, people will be more eager to join your list and watch out for your affiliate promotions

Most Internet marketers succeed at promoting something they are interested in and/or have knowledge

most can tell when you are just going through the motions in promoting something, but not really being interested in it- will hurt your commissions.

Picking a niche you like will also make it easier to do research on the topic

Evaluate what gets you excited, what you talk about often with others, etc.

This is the niche you should be focused on and products in this niche are what you should be promoting to succeed at affiliate marketing.
