The position of a link on a search results page is important. Depending on the search term, organic search results often make up only a small portion of the page. Since ads are at the top of the results page, on a device with a relatively small display -- such as a notebook, tablet or smartphone -- the visible organic search results may consist of only one or two items.
What this means is that if someone visits a website and is logged into their Google account, the site owner cannot see the search keywords they used to get there. This has resulted in a great deal of organic traffic being incorrectly marked as direct. The same thing happened to Apple iOS 6 users carrying out Google searches through the Safari browser, after the operating system’s privacy settings were changed, as Search Engine Land reports.
Remember when you used to rely solely on search engines for traffic? Remember when you worked on SEO and lived and died by your placement in Google? Were you #1? Assured success. Well, okay, maybe not assured. Success only came if the keywords were relevant to your site users, but it was the only real roadmap to generating site traffic and revenue.
