Absolutely nothing (other than the scale of the challenge). Google doesn’t care whether you’re a startup, a major financial institution or the smallest online retailer – all it cares about is connecting people with the most relevant content for each search query. The SEO requirements for a startup are exactly the same as the world’s biggest brands and search engines want to see the same things from you as any other kind of business.
For a long time, digital marketers summed up the properties of direct and organic traffic pretty similarly and simply. To most, organic traffic consists of visits from search engines, while direct traffic is made up of visits from people entering your company URL into their browser. This explanation, however, is too simplified and leaves most digital marketers short-handed when it comes to completely understanding and gaining insights from web traffic, especially organic and direct sources.
