It's hard for digital marketing instructors to keep up with changes in Google's search algorithm and the resulting impacts on search marketing, especially the changes in SEO. Paid search is easier to understand and there are opportunities like the Google Online Marketing Challenge that allow students to gain useful experience in conducting PPC campaigns. There is a chapter devoted to PPC and paid social advertising in edition 4.
Students need to have a basic understanding of both SEO and PPC. Many instructors may choose to leave SEO at the "basic understanding" level, and that's fine. There are many opportunities for marketers to become proficient at SEO, and I wanted to get an idea of how much instruction was the norm. There is, as you might suspect, no such thing as "norm." We looked at one recent list of best SEO training programs and found them offering various aspects of SEO and using multiple sets of training materials and media. That's appropriate for a complex and ever-changing field. It also means that students can access specialized training like SEO for content creators. Encourage students to try free beginner's courses to decide whether paid courses or certification programs are right for them. It also confirms our own experiences in the classroom.
The free SEO training course from HubSpot is a good place to start, especially if you are already using HubSpot Inbound Marketing or other certifications in your classes. It's difficult to give students a working knowledge of SEO in the time available in most digital marketing courses, but it is possible to give an overview. SEO implementation usually requires months of effort so it is difficult to create a project where the result of the student's work can be seen over time. In contrast, paid search projects show immediate results and paid search is becoming more important as the search landscape becomes more crowded and competitive. In addition, SEO is becoming prey to the "Alexa effect," where searchers just want one specific answer and not millions of answers. Because of this phenomenon, good content alone is not the most important thing to "rank" in search. Being able to answer specific questions and be selected for a "featured snippet" and having a recognizable brand will often result in higher rankings.
With that in mind let's concentrate on recent changes and how to cover them at a high level without getting bogged down in technical details. First, there are a number of concepts that students need to be clear about. They are:
- Quality content. The importance of content quality in search ranking is not new and is covered in both editions 3 and 4. Although Google has never provided a precise definition of "quality," experts still regard it as the single most important factor in achieving a high ranking. This recent post has a section on content quality and a good listing of what makes poor quality content.
- Rank brain. The existence of this machine learning algorithm has been known to search marketers since 2015 and was covered in edition 4. MOZ has a succinct explanation: "To “teach” the RankBrain algorithm to produce useful search results, Google first “feeds” it data from a variety of sources. The algorithm then takes it from there, calculating and teaching itself over time to match a variety of signals to a variety of results and to order search engine rankings based on these calculations." This post has a section on Understanding Rank Brain that gives a reasonably simple example of trying to understand search intent that could be adapted for classroom use. This typology of search intent is also useful.
- Featured snippets. Also known as "answer boxes," these content-first query results boxes have been a growing part of search results for several years. I wrote about them in the context of voice search, pointing out that the article that gets the snippet virtually owns the search result real estate and is the only answer to a voice query. They are also extremely important in mobile search where the SERP space is severely limited. The dominance of the snippet in search results is why it is often referred to as "Position 0." Google is the sole determinant of the content chosen for the featured snippet. Content that answers "how to" and "what is" types of questions is more likely to be chosen for a featured snippet.
on the right panel when the user searches for a business entity.
- EAT. Expertise, Authoritativeness, Trustworthiness. In its 2019 Search Quality Evaluation Guidelines, Google states that the first step in ranking the quality of a page is that it has a clear, beneficial purpose and the publication gives detailed examples of website and page objectives. Then the main content (MC) of the page is evaluated according to the expertise of the creator and the authoritativeness and trustworthiness of the "creator of the MC, the MC itself, and the website." (Section 3.2, p. 18).
- YMYL. Your Money or Your Life. According to Google, "Some types of pages could potentially impact the future happiness, health, financial stability or safety of users. We call such pages “Your Money or Your Life” pages, or YMYL." (Section 2.3, p. 9) Google gives examples of YMYL pages that include shopping and financial transactions pages, financial information pages, medical and legal information pages, and a limited set of news pages that are "important for having an informed citizenry." They give several examples of the news category and point out that not all news articles fall into this category.
Warning: the Google publication is 166 pages long, and the table of content alone is 4 pages long. That TOC is really the good news; it is so detailed that is is easy to find relevant content. It's a good idea for anyone who teaches search marketing in any detail to keep this publication handy, as it is an excellent reference. - Broad core updates. Search Engine Land quotes Google's explanation: "Each day, Google usually releases one or more changes designed to improve our results. [My note: MOZ counted an average of 9 updates per day in 2018.] Some are focused around specific improvements. Some are broad changes. Last week, we released a broad core algorithm update. We do these routinely several times per year." These are the "major updates" recorded in MOZ and SEJ timelines. They often have noticeable impact on search engine rankings and are carefully studied by search marketers.
Here are major Google algorithm changes in 2018 from Search Engine Week:
- Any site without HTTPs is considered insecure
- Mobile page speed and mobile-first indexing
- Featured snippets and knowledge panels
- Display of related products in SERPs
- Video optimization
- Image search.
The importance of User Intent has already been mentioned. Another teaching idea is to give the students the MOZ post with the example about the "olympics location" search and assign them to come up with an example of their own and discuss how marketers might understand the intent.
As I discussed in the earlier post, Optimizing for Voice Search continues to be important. Something I've learned on the subject is that asking a query in question form often produces better results than just asking using keywords, thanks to voice search optimization.
In 2018 eMarketer announced that more product searches actually started on Amazon than on Google. That means that Google Search has a competitor besides the other search engines.
The importance of brand as a factor is encapsulated in EAT. A brand must show expertise and authority--must make itself a trusted brand--to rank highly
Google has been rolling out Mobile-First Indexing for several years and its impact has been great. It means that Google looks at a site as a smart phone browser would, not as a desktop browser would. By the end of 2018 mobile indexing was used for more than half of all search results and Google had announced it would be the default for all new sites. This makes user experience on mobile sites a predominant factor in search rankings.
The importance of Featured Snippets has already been highlighted. Essentially, the content that captures the featured snippet will get the lion's share of the traffic for that query. Since many queries are already answered with featured snippets, one strategy is to write "better" content that can replace the current link. The other strategy is to locate relevant queries with no snippet and attempt to optimize for one.
According to Wikipedia, "Latent semantic analysis is a technique in natural language processing, in particular distributional semantics, of analyzing relationships between a set of documents and the terms they contain by producing a set of concepts related to the documents and terms." That may be a field of study that's not familiar to many of us, but it is a technique used in Rank Brain analysis, so LSI keywords could be important. Here's a post from the marketing manager at Alexa that explains in lay marketers' terms.
Technical SEO refers to characteristics of websites that can improve search ranking. Basically, these are the tools Google offers to webmasters. Here is a relatively non-technical description with good additional reference links.
Page Loading Speed has long been an important ranking feature as well as being important to good user experience. Remember that mobile page loading speed is now of special importance.
It's clearly not possible to discuss SEO without technical references. Hopefully this carefully-curated explanation of recent trends will be helpful in the classroom and if you choose to stop at this "overview" level that is great. Students will have a basic idea of how search marketing is changing. The links will provide more detail where you want it.
Note from Mary Lou: Doing the research for this post involved both checking facts that I thought I knew and finding information about issues on which I was pretty clueless--and there were a lot of those! What amazed me through the process was how often I was able to find what I needed by asking the question I wanted to answer and then examining the featured snippets and knowledge boxes that appeared. That alone said something to me about the power and direction of evolving search marketing.
