How long will it take to start seeing improvements in sales? There are fast-acting marketing strategies and longer-terms ones. PPC, or, Pay-Per-Click, is a fast-acting medium through which sales can be generated quickly — often within the first month or two. SEO, however, does take more time but it’s equally important as SEO improves your site ranking and organic traffic over time. Coombined, using longer-term (think slow and steady wins the race) and short-term powerpunches like PPC and retargeting ads yields the best results for increased sales.
