What is search engine optimization (SEO)?
SEO is the process of improving the visibility and relevance of your website in the organic (unpaid) results of search engines like Google and Bing.
Put simply, SEO is how your customers find you online.
It's a set of strategies and best practices that increase the quantity and quality of traffic you get from search. Done well, it brings in people who are already looking for what you do, which makes it one of the highest-intent channels in marketing.
How Google decides what to show
Search engines look at a series of signals to decide which pages to show for a search. If you search for "data-driven digital marketing Columbus, Ohio" (spoiler alert, it's our firm, WolfeDen Marketing 😉), Google weighs:
Meaning
The intent behind the search. In our example: data-driven digital marketing firms in Columbus, Ohio, not Columbus, Indiana or Cleveland, Ohio.
Relevance
The matchmaking between the search and your content. Google looks for pages whose headings and copy actually address the topic, whether as an exact match ("data-driven digital marketing in Columbus Ohio") or a close one ("digital marketing in Columbus Ohio").
Quality
Google prioritizes helpful, original content over generic, low-effort pages. Quality shows up in first-hand expertise, accurate information, useful images or video, and a page that fully answers the question. Length alone doesn't count; usefulness does.
Usability
Your site needs to work well for people. Google measures page experience with Core Web Vitals: how fast the main content loads, how quickly the page responds to a tap or click, and whether the layout jumps around. Mobile-friendliness and security matter too.
Context
The hardest factor to control: a searcher's location, settings and history. Search "football" in the United States and you'll get the NFL; in the UK, the Premier League.
What affects SEO?
- Keywords and topics: the words and questions your buyers use, covered thoroughly in your titles, headings and copy.
- Content: original, accurate, up-to-date pages that are easy to read and genuinely helpful.
- Links and mentions: other reputable sites linking to or talking about you, which builds authority and trust.
- Technical health: site speed, mobile-friendliness, security, crawlability, site structure, sitemaps and canonical tags.
- User experience: clear design and navigation that help visitors find what they need and take the next step.
SEO, AEO and GEO: what's the difference?
You'll hear three acronyms now. Here's the short version:
- SEO (search engine optimization): ranking in the regular search results for the terms your buyers use.
- AEO (answer engine optimization): being the page that answers the question, in featured snippets, "People also ask" and AI Overviews.
- GEO (generative engine optimization): being a source that AI tools like ChatGPT, Gemini, Claude and Google's AI Mode cite and recommend.
They aren't three separate projects. They stack. AEO is built on SEO, and GEO needs both. Skip the foundation and nothing above it holds.

Why SEO still matters when AI answers first
Google now answers many questions with an AI Overview or a conversational AI Mode response. It's fair to ask whether SEO still matters. Google's own answer is yes: its AI features are built on the same search index and ranking systems as regular results. If your pages aren't found in classic search, they won't be cited in AI answers either.
What changes is the reward. Fewer people click on purely informational searches, but the pages that get cited, and the brands people already know and search for by name, capture the attention that's left. Buyers who do click through tend to be further along and ready to talk.
Why this matters for your business
A good SEO strategy helps you build pages that address each of the factors above. That means your business is found more easily, you get more eyes on your services, and you earn credibility before a prospect ever talks to sales.
SEO is also a long-term investment. It takes consistent effort, testing and patience, but the results compound in a way paid channels don't.
