It's especially true now that the big media players are finally waking up to affiliate marketing (NYTime buying WireCutter and SweetHome) and BestReviews (which was already an epic product review site in it's self due to the fact they built their own 10,000 sq ft testing lab) being acquired by Tronc (owns the LA Times and half a dozen more publications).
SEO for organic search: Search engine optimization (SEO) is a marketing tactic in its own right. Good SEO helps you craft post content targeting specific terms, called keywords, to rank high in the search results in Google and other search engines. This is something to understand and implement early to make the most of your content from day one. SEO is also why a narrow niche focus is best for most affiliate marketers. Targeting niche-specific keywords help you rank high in search results and be found by readers interested in your niche.
One other positive about the Ultimate Bundles affiliate program that your readers may not have realized… They actually offer second-tier commissions too, meaning you’ll earn a share of the sales from any affiliates that you refer to the program. In this case, it’s 10% of their bundle sales during their first year as an affiliate which could be a nice earner!
