Text-based content is all well and good, but video can be a valuable asset in both attracting new visitors and making your site more engaging. Data shows that information retention is significantly higher for visual material than it is for text, meaning that video marketing is an excellent way to grab – and hold – your audience’s attention, and boost traffic to your website at the same time.

Meta tags. Meta tags still play a vital role in SEO. If you type any keyword into a search engine, you’ll see how that keyword is reflected in the title for that page. Google looks at your page title as a signal of relevance for that keyword. The same holds true for the description of that page. (Don't worry about the keyword title tag -- Google has publicly said that it doesn't pay attention to that tag, since it has been abused by webmasters and all those trying to rank for certain keywords.)
Expert roundups have been abused in the Internet Marketing industry, but they are effective for several reasons. First, you don’t have to create any content. The “experts” create all the content. Second, it is ego bait. Meaning, anyone who participated in the roundup will likely share it with their audience. Last, it is a great way to build relationships with influencers.
The most basic and straightforward way is to use Google Analytics. And I'm not just talking about installing Google Analytics. I'm talking about using the UTM (short for Urchin Tracking Module, which relates to the old Urchin analytics system that Google acquired to create its tracking tool) variables that exist in Google's Analytics to ensure that you know where they're coming from.
WOW. I consider myself a total newbie to SEO, but I’ve been working on my Squarespace site for my small business for about 3 years and have read dozens of articles on how to improve SEO. So far, this has been the MOST USEFUL and information-packed resource I’ve found so far. I’m honestly shocked that this is free to access. I haven’t even completely consumed this content yet (I’ve bookmarked it to come back to!) but I’ve already made some significant changes to my SEO strategy, including adding a couple of infographics to blog posts, changing my internal and external linking habits, editing meta descriptions, and a bunch more. Thanks for all the time and passion you’ve out into this.
