You don't need a tool, you need a good strategy. You have few products ready to be sold, so, to complete the process you need a traffic and conversion. You can have some paid traffic from social networks, search engines, forums and other advertising websites. For the conversion you need a well built website and attracting products that your visitors will want to buy.
Research and Join Affiliate programs. Amazon, EBay and Flipkart are amongst the few who offer products for Affiliate Marketing in your niche. Study them very well before signing up. If a company is asking you to provide credit card it means you might be getting scammed. As this companies give commission on sale so they might ask you for your bank details or PayPal account number. Affiliate programs are usually free of charge.
If you would like to take a more subtle approach, include a product or service from your company that relates into your blog post. For example, let’s say that you are a wine connoisseur and that is what your blog is based around. In any post that is enticing your readers to open up a good bottle of Merlot or what have you, it would be wise to embed an ad for a quality, easy-to-use wine opener, wine glasses or stoppers that keep the wine fresh.
And what about joining another company's affiliate program? It's all about extra revenue. Think about your customers' needs: What other products or services would interest your site visitors? Join those affiliate programs. Affiliate programs can increase your sales with no upfront cost to you. It just takes a little time to plan your strategy and select the partners that will have the greatest impact on your business.
