Search Has Changed. Here‘s How Your Content Needs to Evolve

The way people search online has changed dramatically in the past decade. Ten blue links are no longer enough to satisfy searchers who expect answers to complex questions at their fingertips. At the same time, search engines like Google have gotten smarter, redefining their algorithms to better understand intent and context.

As a result, the traditional SEO playbook of keyword stuffing and mass producing blog posts is no longer effective. To rank well and attract organic traffic from search today, content creators need to overhaul their approach. The solution lies in organizing content into topic clusters.

The Seismic Shift in Search Behavior

Think about how you used Google a decade ago. You probably typed in fragmented keywords like "iPhone reviews" or "best Italian restaurants NYC." The results were a mixed bag, and you had to sift through them to find what you were looking for.

Now, 64% of searches are four words or longer, with many taking the form of complex questions.¹ For example, you might ask your phone‘s virtual assistant, "What‘s the highest-rated Italian restaurant near me that takes reservations?"

Several trends are driving this shift to longer, conversational searches:

• The rise of mobile: With mini computers in our pockets, we can search on the go anytime a question pops into our heads. Over 60% of searches now take place on mobile devices.²

• The growth of voice search: Siri, Alexa, and other virtual assistants have made it natural to ask questions out loud rather than typing keywords. 27% of the global online population uses voice search on mobile.³

• Searchers expect direct answers: When you have a question, you don‘t want to dig through pages of results. You expect search engines to infer what you need and serve up a relevant direct answer in a featured snippet.

Take the query "How to make pizza dough." The top search result is a rich snippet from a recipe site listing out the ingredients and steps. There‘s no need to even click through to the page to get the core information.

To adapt to these changes in search behavior, Google has released a series of major updates to its search algorithm over the past decade. Let‘s walk through how those updates have made keywords less important and topic authority more essential than ever before.

How Google Killed the Keyword (Sort of)

Keywords aren‘t completely dead. Including relevant terms in your content still sends signals to Google about what topics you cover. However, the days of identifying dozens of long-tail keyword variations and creating pages optimized for each one are long gone.

Over the years, Google‘s algorithm updates have chipped away at the power of individual keywords in favor of understanding the meaning and intent behind queries. Here are the key updates that changed the game:

The Hummingbird Update (2013)

Google‘s first major push toward semantic search, Hummingbird helped the search engine better interpret the meaning and context behind queries.⁴ Rather than just looking for pages containing the words in a search, Google started analyzing how those words worked together to infer intent.

The RankBrain Update (2015)

Powered by machine learning, RankBrain helps Google understand complex searches and serve up the most relevant results, even if the exact keywords aren‘t present on a page.⁵ RankBrain also looks at how searchers interact with results and adjusts rankings accordingly. So if you optimize for the wrong keywords, RankBrain will pick up on searchers bouncing from your site and penalize you.

The BERT Update (2019)

Perhaps the biggest leap forward in natural language processing by a search engine, BERT helps Google grasp nuance and context in queries.⁶ In particular, BERT improves Google‘s understanding of prepositions like "to" and "for" and how they affect the meaning of a query (e.g. "2019 brazil traveler to usa" vs. "2019 usa traveler to brazil"). With better comprehension of natural language, Google can surface results that match the true intent behind a search.

So where does this leave keyword research? It‘s still an important piece of the puzzle, but in the context of understanding what questions searchers are asking about a given topic. The goal is no longer to optimize individual pages for a matrix of long-tail keywords, but rather to create authoritative resources that comprehensively cover topics.

The Rise of Topic Clusters: A New Model for SEO

Savvy content marketers are adapting to this new reality of search behavior and technology by shifting to a topic cluster model. In this approach, content is organized around main topics, with a single pillar page acting as a hub linking to more specific cluster content.

Visually, it looks something like this:

The topic cluster model sends clear signals to search engines about the semantic relationship between pages and establishes broader topical authority. When multiple pages on your site are closely related and link to each other, it helps Google understand that your content covers a topic in-depth.

Take the topic of "content marketing" as an example. A pillar page might broadly explain what content marketing is, how it works, and why it‘s important. Cluster content would then dive into subtopics like content marketing strategy, tools, and examples.

By linking all of these related pieces together, you create a hub of comprehensive information on the topic. This signals to Google that your site is an authority on content marketing and helps you rank for a variety of long-tail keywords related to the topic.

Here‘s an example of what a topic cluster on content marketing might look like:

Let‘s break down the key components of a successful topic cluster in more detail.

Anatomy of an Effective Pillar Page

A pillar page is the foundation of a topic cluster. This is a comprehensive guide on the main topic you‘re trying to rank for, usually in the form of a long-form blog post or resource page.

Some key characteristics of a pillar page include:

• Length of 2,000-5,000+ words
• Covers all core aspects of the topic
• Answers common questions searchers have
• Includes jump links to navigate the content
• Links out to cluster pages that cover subtopics in more depth
• Optimized for relevant head keywords (e.g. "content marketing")

The goal of a pillar page is to be the best resource on the web for the given topic. By covering the topic comprehensively, you signal to Google that your page deserves to rank highly when people search for questions related to that topic.

Supporting Cluster Content

Branching off from the pillar page are more specific cluster pages that target long-tail keywords and go in-depth on subtopics. Often these take the form of blog posts, tutorials, or product pages.

Here are some best practices for cluster content:

• In-depth, typically 500-1,000+ words
• Each page focuses on a specific long-tail keyword or question
• Relevant to the main topic, but covers unique aspects
• Links back to the pillar page and other related cluster pages
• Demonstrates expertise on the subtopic

By creating a web of topically related content, you build topical authority that carries over to your main pillar page. Internal linking with keyword-optimized anchor text also helps send semantic signals to search engines about how all of the content fits together.

Shifting to a Topic Cluster Strategy

For many content teams used to chasing long-tail keywords, shifting to a topic cluster model requires a complete overhaul of their content strategy and editorial calendars. But the benefits are well worth the effort.

Consider these results from HubSpot after shifting their blog to a topic cluster model:⁷

• Organic traffic to the entire blog increased by over 50%.
• Organic traffic to pillar posts themselves increased by an average of 90%.
• Leads generated by the blog almost doubled.

To implement a topic cluster strategy, follow these key steps:

1. Identify core topics: Pinpoint 5-10 main topics your business wants to rank for based on relevance to your products/services, search volume, and competitive landscape. These will form the basis of your pillar pages.

2. Perform keyword research: For each core topic, identify subtopics, common questions, and long-tail keywords to target in cluster content. Use tools like Ahrefs, SEMrush, and Answer the Public to discover search trends.

3. Map out cluster architecture: Outline how your pillar pages and cluster content will link together. Each pillar page should be the main hub for a single topic and link to 20-30 related cluster pages.

4. Create pillar content: Either repurpose existing content or create new in-depth guides to form your pillar pages. Make sure to comprehensively cover the topic and include relevant header tags and keywords.

5. Add internal links: As you create new cluster content, always link back to the main pillar page with descriptive anchor text. Also link to other relevant cluster pages when it makes sense.

6. Monitor and optimize: Measure the organic traffic and rankings for your topic clusters over time. Look for opportunities to improve and expand your cluster content to cover additional subtopics and target new keywords.

By taking a deliberate, organized approach to content creation focused on topics over keywords, you can get ahead of the curve and set yourself up for sustainable organic traffic growth.

The Future of Search and Content

As new technologies like visual search and conversational AI continue to emerge, the way people search will keep evolving. We‘re not far from a future where you might show your smart glasses a unique flower and ask what it is, or where you‘ll have full conversations with virtual assistants to get customized recommendations.

Content creators need to be ready to adapt as these changes unfold. But the core principles of a topic cluster model – creating comprehensive, semantically related content and establishing topical authority – will likely remain crucial.

By putting a topic cluster strategy in place now, you‘ll be well-positioned no matter what the future of search holds. Focus on becoming the best resource for your target topics, and you‘ll be able to meet searchers‘ needs regardless of how they choose to look for information.

The key is to always keep your audience at the center of your content strategy rather than chasing arbitrary algorithms. If you relentlessly work to help your audience find the information they need, the search traffic will follow.
