One of the options for your site is to ad links to other websites you may have or links within your website. This is used for many reasons but the most important is for your website SEO. By adding links to other pages of your site you are creating what is called internal linking, or if you add links to your other websites this is called back-links and both will help with search engine ranking.
Now just because backlinks are important you do not want to load your pages with to many links going out of your site, that is why there are only limited number of links you can enter. Remember this is an affiliate website and you already have many links from amazon and ebay items. If you put to many links on your page it will hurt your page ranking.
There are two section where you can enter other website links or internal. This is pretty straight forward but we have entered some examples for you. In both sections you have the title or description of the links. Don’t enter the site domain in this sections, enter some keyword string. For example if you have another website about iphones than enter something like “Get new unlocked iPhones at discount” This will help improve your iphone sites search ranking that search string or keyword.
That’s the basic, short version of how this links can help your site(s).
