My takeaways for 2018.
Expect less organic traffic to your websites, as Google continues to use featured snippets and other types of instant answers that do not require users to visit a website.
This points to a need to keep your keywords and phrases optimized for placement as snippets or knowledge-based answers that will drive traffic and customers to your website.
Also, the loss of net neutrality will kick in this year. The big players will get the bandwidth, while smaller businesses and non-traditional sites may have to fight for access or be blocked.
This includes slower load times as the smaller sites are put on the equivalent of a "side road".
This points to the need to keep your technical SEO honed so your site loads as quickly as possible so that you are penalized as little as possible by these changes.
WordPress is the dominant website platform, and this will continue for 2018. Self-hosted WordPress gives you the most control over your website, especially regarding load speed, which is a critical ranking factor for doing well in search results.
Content is still King. Keep your content compelling, targeted, and of high quality. Craft compelling titles. What problem is your content solving? What pain points does it address for your clients or customers?
Mobile first, mobile first, mobile first. Design your website and content to work well and read easily on a mobile. Make sure your content loads quickly, and that your fonts -- including your logo -- may be read on small screen.
