Let’s say you have a promotions page where you’re promoting a product via affiliate links. If you currently get 5,000 visits/month at a 2% conversion rate, you have 100 referrals. To get to 200 referrals, you can either focus on getting 5,000 more visitors, or simply increasing the conversion rate to 4%. Which sounds easier? Instead of spending months building domain authority with blogging and guest posts to get more organic traffic, you just have to increase the conversion rate by 2%. This can include landing page optimization, testing your calls-to-action, and having a conversion rate optimization strategy in place. By testing and optimizing your site, you’ll get far better results with much less effort.
If you actually use the product and get results with it, then sharing a case study or your personal experience can be one of the most effective ways of selling those products to your audience. As you build a more responsive list of email subscribers and buyers and your reputation, merchants may offer you “free” samples of e-books or other products.

Does affiliate marketing still work, as Google doesn’t allow affiliate links or the promotion of affiliate links. So I can’t create an ad directing to an affiliate link, and I can’t create a landing page (and promoting the landing page), with a single purpose of sending users to the affiliate link. Except RTB platforms and Blog based SEO that takes years to build, how can I do affiliate marketing ?

Once you acquire a new customer through one of your affiliate partners, they've entered your ecosystem and you can direct market to that customer without going through your affiliates. Remember to consider that long term value of your customers into the equation when deciding your commission structure. For many businesses, I wouldn't care if I broke-even on affiliate sales – so long as I had a way to maximize the long term value of each new customer they brought me. As you probably know from experience, breaking even on acquiring customers to your sales funnel is nothing to sneeze at in e-commerce. There are many circumstances where I'd literally do that unlimited times if given the option!
Write a blog. If you have a business, consider starting a blog as part of your marketing plan. You can write how-to articles, product reviews, answers to questions and posts about upcoming events. Blogs give you more flexibility than other forms of social media like Facebook or Twitter because you own the content and aren’t bound by a third party’s rules or restrictions. Also, if your posts include keywords or phrases and link to internal and external content, you can improve the search optimization of your website. Blogs drive sales because you can include product information and links to product pages.
