Conduct a quick Google search using “site:yourwebsite.com” to make sure your pages are actually indexed. If you’re noticing that critical pages aren’t appearing in the SERPs, you’ve likely found the culprit. Check your robots.txt file to make sure you haven’t blocked important pages or directories. If that looks good, check individual pages for a noindex tag.
The term “organic traffic” is used for referring to the visitors that land on your website as a result of unpaid (“organic”) search results. Organic traffic is the opposite of paid traffic, which defines the visits generated by paid ads. Visitors who are considered organic find your website after using a search engine like Google or Bing, so they are not “referred” by any other website.
