Natural referencing, also called SEO (Search Engine Optimization) complements paid acquisition campaigns (Google Ads, Bings Ads, Facebook Ads, Amazon Ads, etc.) and in many cases represents an important acquisition lever. It allows you to generate an unlimited number of visitors, thus converting on your website at no additional cost. This is a long-lasting operation because a well-referenced site and good positioning in search engines generate a large number of qualified regular visitors. It is for this reason that Optimum Circle positions itself as a natural reference agency with results proven by tools such as Google Analytics or Google Search Console.
