You built the website. You picked the colors. You wrote the copy. And still: crickets. Nobody’s showing up. No traffic, no leads, no love from Google.
That’s an SEO problem. And honestly? It’s a fixable one.
This blog breaks down what SEO actually is, how it works, and why it matters. Then we’re going deep on seven different types of SEO, because there’s way more to it than keywords and blog posts. We’re talking technical stuff, local visibility, AI search, and more.
Oh, and by the way, we’re The Illunis Co. We build websites that look great and actually get found. Stick around.
So… What Is SEO, Really?
SEO stands for search engine optimization. In plain English: it’s how you help Google (and other search engines) understand what your website is about so they can show it to the right people.
How does SEO work? Search engines crawl your pages, read your content, check your site speed, look at who’s linking to you, and judge whether your site is actually useful. Good SEO = higher ranking. Bad SEO = buried on page five where no one goes.
Why is SEO important? Because it’s how people find you without you paying for every single click. Done right, SEO brings the right visitors to your site, the people who are actively searching for what you offer.
There are seven main types of SEO: on-page, off-page, technical, content, local, AEO, and GEO. Each one does something different. Together, they’re your full visibility strategy.
1. On-Page SEO
On-page SEO is everything that lives on your actual website. It’s the stuff you control directly. Think titles, headings, internal links, image descriptions, and the words on the page.
This is where on-page SEO services come in. A good SEO team looks at every page and makes sure it’s clear, keyword-smart, and easy for both people and search engines to navigate.
Some SEO best practices to start with:
- Write page titles that include your main keyword and actually make sense
- Write meta descriptions that make someone want to click
- Use headers (H1, H2, H3) to break up your content
- Link to other pages on your site so visitors and bots can explore
- Add alt text to every image. Describe what’s actually in it
- Keep your sentences short and your words simple
On-page SEO is your foundation. Get this right and everything else works better.
2. Off-Page SEO
Your website could be perfect and still struggle to rank if nobody else is talking about it. That’s the gap off-page SEO fills. It’s about building your reputation across the internet, through backlinks, mentions, reviews, and shares. When other trusted sites link to yours, search engines treat it as a stamp of approval.
How to build that reputation:
- Get backlinks from real, trusted sites (not sketchy link farms)
- Write guest posts on legit blogs with a link back to your site
- Make sure your business name, address, and phone number match everywhere online
- Ask happy customers to leave reviews. Then actually ask them
- Share your content on social media consistently, not just once and never again
Off-page SEO is how you prove your site matters, not just to you, but to the internet.
3. Technical SEO
You know that website that looks gorgeous but takes forever to load? Technical SEO nightmare. This type of SEO lives in your site’s code and infrastructure. Not the words or links, but the bones.
If Google can’t crawl your site, it won’t rank your site. Doesn’t matter how good everything else is.
Things that fall under technical SEO:
- Page speed: compress images, clean up code, cut load time
- Mobile-friendliness: if it’s broken on a phone, it’s broken
- Sitemaps: Google uses them, so you should submit one
- Crawl errors: use Google Search Console to find and fix broken pages
- Schema markup: helps search engines understand what type of content you have
Technical SEO is unglamorous. But it’s the difference between a site that gets indexed and one that doesn’t.
4. Content SEO
No content, no ranking. It’s that simple. Content SEO is about creating things people are actually searching for, written in a way that’s genuinely useful.
Google rewards websites that stay on topic, answer questions clearly, and keep their content current. Content SEO tells search engines you’re not just filling pages with random words.
SEO best practices for content:
- Research keywords people are actually typing, not what you assume they’re typing
- Write to solve problems and answer questions directly
- Group your content by topic and link related pages together
- Update old content, because stale pages lose rankings over time
- Always write for people first, algorithms second
When your content genuinely helps people, search engines take notice. That’s the whole game.
5. Local SEO
If you serve a specific city, region, or physical location, local SEO is non-negotiable. This is how you show up when someone nearby searches for what you do.
Think about it. When someone searches “website designer near me” or “coffee shop in Austin,” Google serves local results. Without local SEO, you’re invisible to those searches, even if you’re literally around the corner.
How to get local SEO right:
- Claim and fully fill out your Google Business Profile, including photos, hours, and services
- Make sure your name, address, and phone number (NAP) are identical across every directory
- Get listed on local directories like Yelp, Apple Maps, and industry-specific sites
- Collect Google reviews, since they directly affect your local ranking
- Create location-specific pages or content if you serve multiple areas
Local SEO is how your business gets found by the people who are closest to actually buying from you.
6. AEO: Answer Engine Optimization
Search is changing. People don’t just want links anymore. They want answers. That’s where AEO comes in.
AEO (answer engine optimization) is about structuring your content so search engines can pull a direct answer from your page and show it right at the top of results, in featured snippets, “People Also Ask” boxes, or voice search responses. No click required. Your brand just becomes the answer.
How to optimize for answer engines:
- Answer questions directly and concisely, ideally in the first 1 to 2 sentences of a section
- Use real questions as headings, like “What is SEO?” or “How does SEO work?”
- Add FAQ sections to your pages
- Use structured data (schema markup) so search engines know what type of content you have
- Keep answers tight. 40 to 60 words tends to hit the sweet spot for featured snippets
AEO is how you stop competing for clicks and start owning the answers.
7. GEO: Generative Engine Optimization
This one is the newest and probably the most important to understand right now. GEO stands for generative engine optimization, which is about getting your content cited by AI tools like ChatGPT, Google’s AI Overviews, Perplexity, and similar platforms.
When someone asks an AI assistant a question, it pulls information from websites it trusts. GEO is how you become one of those trusted sources.
How to show up in AI-generated answers:
- Write with authority and depth. AI tools favor content that actually explains things well
- Be specific and factual. Vague content doesn’t get cited
- Use clear structure (headings, lists, definitions) so AI can easily extract information
- Build your brand’s online presence. Mentions, links, and credibility all contribute
- Keep content current, since outdated info is less likely to be surfaced
GEO isn’t replacing traditional SEO. It layers on top of it. The better your SEO foundation, the better your odds in AI search too.
