Breaking it down, Traffic Cost is SEMRush’s way of showing the hypothetical value of a page. Traffic Cost estimates the traffic a page is getting by estimating clickthrough rate (CTR), and then multiplying it against all the positions it ranks for. From there, it looks at what others would be willing to pay for that same traffic using Google AdWords’ CPC.
Email marketing is still a highly effective channel for driving traffic to your website. However, it’s definitely evolved since the times of promotional blasts. Building a sequence that nurtures new sign-ups and develops a relationship is now an essential part of email marketing. In fact, even the basic welcome email is better than an old-school transactional one. According to a recent study, 320% more revenue is attributed to welcome emails than other promotional emails, so it definitely pays to have some kind of autoresponder series in place.
I've tried affiliate marketing in the past without a lot of success, so wasn't sure that this book would help me much with giving it another shot. However, I was pleasantly surprised. There's no fluff or filler in this book - it's obviously written by someone who knows what they're talking about and it covers (in detail) what it promised - how to get started (and be successful) in affiliate marketing. I especially appreciate that the author added sections that aren't typically covered in these kinds of books, like how to use videos and bookmarking in your efforts as well as how to deal with backlinking after Google's Penguin and Panda updates. Glad I picked this one up. It's a keeper.
Like you I am a scientist and like you did in the past, I am currently working on translating great scientific literature into tips. In my case it’s child development research into play tips for parents. I can already see that the outcome of my experiment is going to be the same as yours. Great content but who cares. I hadn’t even thought about my key influences. I know some important ones, but don’t see how they would share my content. I thought I was writing content for my potential customers. Is your SEO that works course the same as the content that gets results course? Sorry if I sound a bit dim asking that question.
