It might happen to have some lost links from now and then or a broken page due to some crawling issue or something similar. Yet, when your broken pages and links form up a figure just as big as your phone number, then you might be facing a problem; in terms of site user experience and organic traffic as well. Your bounce rate will increase, your overall usability, you will be loosing links and therefore you will start asking yourself “why did my organic traffic drop”?
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.
