Brankica, Very comprehensive list there. Can't think of anything else :D RT! I think the traffic sources that I hardly use is answering questions. I find that traffic conversion there is poor for me, so I don't focus too much on it. I think of all those in the list, focus on those that gives you the best kind of traffic. Forums can be a particularly useful one especially when people are there asking for help. Answering their questions and giving them a link that benefits their query is one good way of getting the right kind of traffic.
If your referrers have moved to HTTPS and you’re stuck on HTTP, you really ought to consider migrating to HTTPS. Doing so (and updating your backlinks to point to HTTPS URLs) will bring back any referrer data which is being stripped from cross-protocol traffic. SSL certificates can now be obtained for free thanks to automated authorities like LetsEncrypt, but that’s not to say you should neglect to explore the potentially-significant SEO implications of site migrations. Remember, HTTPS and HTTP/2 are the future of the web.
While it’s best to create a custom dimension for filtering out bots, applying the generic bot filter is a good place to start. It’s important to note that filters cannot be applied retroactively, so if you’ve recently turned on this feature, you should be receiving less traffic. Additionally, double-check that you are filtering out your own traffic and IP address.
According to our data, twenty-three out of the twenty-five largest retailers use Product Listing Ads (PLAs), which are cost-per-click ads that are purchased through AdWords to promote products. Google initially launched Product Listing Ads in the US market in 2011. However, the advertising format experienced an astronomical rise around 2014, when the search engine launched the feature in other countries. Today, PLAs account for 43 percent of all retail ad clicks and a staggering 70 percent of non-branded clicks!
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.
