Hi SEO 4 Attorneys, it could be any thing is this for your site for a clients site.It could be an attempt at negative SEO from a competitor? The thing is people may try to push 100's of spammy links to a site in hopes to knock it down. In the end of the day my best advice is to monitor your link profile on a weekly basis. Try to remove negative links where possible if you cant remove them then opt for the disavow tool as a last resort. 
Secure (https) to non-secure sites (http): Since Google began emphasizing the importance of having a secure site, more websites are securely hosted, as indicated by the “https” in their URLs. Per the security protocol, however, any traffic going from a secure site to a non-secure site will not pass referral information. For this issue, you can correct by updating your site to be secure through a third-party SSL certificate.
With the exception of crude oil and Picassos, very few industries are “recession-proof” and experience an inelastic product demand. Look at how your competitors are faring, and see if they’re experiencing the same problems. While you should take Google Trends data with a grain of salt, looking at the bigger picture may help provide some clarity. I’d suggest taking this a step further by conducting trends research and reading industry reports.
Thank you Jayne, for doing all that voting and sharing, means the world to me! I am glad you saw some new ideas and looking at all the comments, I think I killed a really bug tree with this post, that is how many people want to print it out, lol. If at any point of time you get stuck with one of these, send me an e-mail, tweet, what ever and I will try to help you with extra ideas :)

If you’ve done all of this, and you’re still not getting the traction you’re looking for… you may need to take a closer look at the other aspects of your digital marketing strategy. Are you using creative content marketing ideas to send positive signals to search engines about your content? Are you leveraging your social media accounts to send a steady stream of traffic to targeted pages? What’s your backlinking strategy? Are you using tools like HARO to earn valuable backlinks to your optimized content? Each of these is one piece of the puzzle, and a fully developed strategy always produces the strongest results.
For reasons we’ve already discussed, traffic from bookmarks and dark social is an enormously valuable segment to analyze. These are likely to be some of your most loyal and engaged users, and it’s not uncommon to see a notably higher conversion rate for a clean direct channel compared to the site average. You should make the effort to get to know them.
Hey Matt, thank you so much for such a great compliment. I had my head spinning when I started pulling up all the traffic sources for this post. I tried them all and recommend everyone to do it. But definitely not at once, lol. It would be great to choose one or two and try them out. Every niche is a story for itself and I am sure one of these sources you haven't tried before can bring great traffic to you.
Search engine optimisation is tricky for any business, but you’ve got a real challenge on your hands as a startup. You need to make an impact fast, get things moving and start building traction before those limited funds run out. Which is probably why a lot of startups take shortcuts with SEO, hoping to cut a few corners and speed their way to search ranking glory.
Mobile traffic: In the Groupon experiment mentioned above, Groupon found that both browser and device matter in web analytics’ ability to track organic traffic. Although desktops using common browsers saw a smaller impact from the test (10-20 percent), mobile devices saw a 50 percent drop in direct traffic when the site was de-indexed. In short, as mobile users grow, we are likely to see direct traffic rise even more from organic search traffic.
