Strong SEO now reaches beyond Google. A page that loads fast, answers the searcher’s task, and is structured clearly enough for both crawlers and AI systems to extract stands a better chance of earning rankings, mentions, citations, and agent-driven traffic across surfaces such as AI Overviews, AI Mode, ChatGPT, Gemini, Perplexity, voice assistants, recommendation systems, and AI agents acting on a user’s behalf. The ten practices that follow cover building the foundation that qualifies a page to compete, adding the signals that give search engines and AI systems a reason to choose it, and adapting the site for agentic search while measuring what changes.
What counts as an SEO best practice in 2026
An SEO best practice is a repeatable method that helps search engines and AI systems access, understand, trust, and surface your content. The discipline now influences more discovery surfaces than it used to. Alongside traditional Google results, people encounter brands through AI Overviews, AI Mode, ChatGPT, Gemini, Perplexity, voice assistants, recommendation systems, and AI agents acting on a user’s behalf.
Foundations still matter. Search intent, useful content, technical accessibility, expertise, authority, and trust are evaluated and reused across Google results, AI Overviews, AI Mode, ChatGPT, Gemini, Perplexity, voice assistants, recommendation systems, and AI agents. Following the basics does not guarantee visibility: no technical setting substitutes for useful content, hundreds of thin pages do not automatically beat a smaller collection of useful ones, and making a page crawlable does not give Google or an AI platform a reason to recommend it. What earns the ranking, mention, or citation is usually built on top of the basics with original evidence, stronger expertise, fuller coverage of the user’s task, and recognition from sources beyond your own site.
The three layers
The practices below sit in three groups.
- Build the foundation. Match search intent, develop topical authority, structure content clearly, remove technical barriers, and optimize images. These practices help content qualify to compete.
- Give systems a reason to choose you. Show expertise, publish original findings, and get recognized on other sites. These signals can help you earn rankings, mentions, links, and citations.
- Adapt and measure. Make the site easier for AI agents to use, then track visibility across both Google and AI platforms.
1. Understand what your audience wants
Content earns visibility when it matches what people are actually trying to accomplish. That goal is search intent. Someone searching for “best SEO tools” usually wants to compare products before choosing one, so the intent for that term is commercial. Start with keyword research to find what the audience searches for and how often. Enter a broad topic into a keyword tool, then look for terms with real search volume and a difficulty score the site can compete at. A prompt research tool can also reveal the intent behind topics and prompts used across AI platforms.
Intent is more than a label like “commercial” or “informational.” Think about the complete task behind the search, including the questions users want answered, the information and format they expect, the criteria they use to decide, and likely follow-up questions. People Also Ask results, communities, reviews, support tickets, and customer conversations often surface needs and language that keyword data misses.
Write for how people ask AI
Queries typed into Google tend to be short, such as “best CRM small business.” The same person might ask ChatGPT, “What’s a good CRM for a growing business that’s easy to use and doesn’t cost a fortune?” The longer version spells out what they care about: price, ease of use, and room to grow. Build those details into the page, and review Reddit threads, sales calls, and AI prompt data to see how the audience describes the problem in their own words.
Give each page one clear primary intent. Closely related terms like “SEO best practices,” “best SEO practices,” and “best practices for SEO” can usually be covered together when they serve the same underlying need. Prioritize satisfying the task, not matching keywords one by one.
2. Focus on topical authority
Topical authority comes from covering an important subject deeply across a group of useful, connected pages. It helps search engines and AI systems recognize the site as a credible source on topics relevant to the business. Google’s December 2025 core update appears to reward topical authority, showing another iteration that favors specialization, expertise, and more commercially oriented content from brands or specialized retailers over generic ecommerce platforms or publications.
A common way to build topical authority is with topic clusters. Pick a core topic related to the business, then create a pillar page that gives a broad overview of the topic. Write supporting cluster pages that cover related subtopics, and use internal links to connect the pillar page and cluster pages so readers, search engines, and AI tools can navigate the content and see how it relates. Regularly update the content with new insights, data, and examples to show that it remains relevant. The goal is to build enough useful depth that the site becomes a credible resource on the topics that matter to the audience and the business.
Refresh and improve existing content
Building topical authority does not always mean publishing more content. Often, more value comes from improving pages that already have some visibility or authority. Start with pages already earning search impressions or rankings, organic traffic, backlinks or brand mentions, or AI mentions or citations. Identify them in a top-pages report, then look for ways to make each page meaningfully better: update outdated advice or examples, expand weak or incomplete sections, add missing examples, evidence, or firsthand experience, support claims with stronger sources, fill gaps in intent coverage, and strengthen internal links to and from related pages. Simply changing the publication date or making minor wording edits is not a real content refresh.
3. Structure content so search and AI systems can extract it
Clear structure makes content easier for readers to scan and helps search engines and AI systems identify useful passages to surface. Start with the basic on-page SEO signals. Include the primary keyword naturally in the title tag, H1, and meta description, and make sure each one accurately reflects the page’s topic and search intent. The title tag and H1 do not need to match word for word, and the meta description is not a direct ranking factor, but all three should make it immediately clear what the page is about.
Within the content, use descriptive headings that clearly explain what each section covers, then answer the heading directly, ideally in the first sentence or paragraph. Make content easier to understand and extract by keeping paragraphs relatively short and focused on one idea, using lists for steps, examples, or grouped information, using tables when readers need to compare options, defining unfamiliar terms clearly, breaking long sections into useful subheadings, and keeping important claims understandable without relying heavily on surrounding paragraphs.
That last point is particularly useful for AI search. Pages cited by AI may score about 33% higher on clarity and summarization than pages that only ranked in Google, 25% higher on Q&A formatting, and 23% higher on section structure. AI systems often retrieve or quote individual passages rather than reproducing an entire page, so an important statement should make sense when taken out of its original context. “It can improve visibility” is difficult to interpret on its own; “Building topical authority can improve search visibility” is more self-contained. Think of this as making content quotable rather than simply adding more formatting.
4. Do technical SEO, including AI crawler access
Technical SEO matters because content cannot earn visibility if search systems cannot reliably access and process it. A sound technical foundation, including AI crawler access, also helps AI agents navigate the site, interpret key elements, and complete actions reliably on a user’s behalf. Before diagnosing rankings or traffic, confirm that important pages are actually indexed, then check for issues such as crawl blocks or accidental noindex directives, incorrect canonicals, broken links and redirect chains, XML sitemap problems, poor mobile usability or page performance, and important content that depends on JavaScript to render.
A site audit tool can surface these issues at scale. An AI search-specific module can flag pages blocked from AI crawlers. Cover the basics: speed, mobile usability, security, and crawlability. Manage search and AI bot access via robots.txt, and verify that the structured data on key pages is valid using a rich results test.
5. Optimize images for search
Optimized images improve user experience and are more likely to gain search visibility. Use descriptive file names that reflect what the image actually shows, add alt text that describes the image for accessibility and for crawlers that cannot see the image, compress files to keep page weight down, and enable lazy loading so off-screen images do not slow the page.
6. Showcase E-E-A-T
Content written by credible experts with real experience is more likely to perform well and be cited. E-E-A-T, which stands for experience, expertise, authoritativeness, and trustworthiness, is the framework search systems use to weigh that credibility. Show it by adding author bios with relevant background, citing reputable sources, and including real examples or first-hand data that only someone with experience could provide.
7. Publish original data and citable evidence
First-hand data gives publishers and AI systems a specific reason to cite the page over a generic competitor. A research hub or ongoing data series, such as annual industry benchmarks or proprietary survey results, creates assets that other sites and AI systems reference, which builds recognition beyond the site’s own pages.
8. Build an off-site presence where search and AI systems look
Brand mentions and backlinks from trusted sources build the credibility AI systems look for. Backlink and brand monitoring tools surface where the brand is already being talked about and where new opportunities exist. Create useful content worth linking to, use direct outreach to build relationships with relevant sites, and prioritize relevant placements over high-volume generic links.
9. Prepare for agentic search and commerce
AI agents need accurate, structured data and a well-maintained accessibility tree to act on the site on a user’s behalf. Keep pricing, specs, inventory, and product identifiers accurate. Use Product and Offer markup and structured data feeds so agents can read what the page offers, and run an accessibility scan to confirm the site is usable for both people and agents.
10. Monitor performance across Google and AI search
Measure results to see whether SEO efforts are working, and go beyond rankings and traffic to capture the full value of SEO. Track organic rankings, AI mentions, citations, and Share of Voice over time using a position tracking tool combined with an AI visibility toolkit. Visibility across AI platforms is now a measurable outcome alongside traditional Google rankings, and both belong in the same reporting view.
FAQ
What is an SEO best practice?
An SEO best practice is a repeatable method that helps search engines and AI systems access, understand, trust, and surface your content. The same fundamentals now apply to AI Overviews, AI Mode, ChatGPT, Gemini, Perplexity, voice assistants, and AI agents, not just traditional Google results.
What are the most important SEO best practices?
The practices that move the needle most are matching search intent, building topical authority through topic clusters, structuring content so AI systems can extract passages, keeping the site technically accessible including to AI crawlers, demonstrating real E-E-A-T, publishing original data and citable evidence, building off-site recognition through mentions and backlinks, preparing for agentic search with accurate structured data, and monitoring visibility across both Google and AI platforms.
Do SEO best practices still matter with AI search?
Search intent, useful content, technical accessibility, expertise, authority, and trust still underpin these systems, and newer platforms increasingly read and repurpose that content in the same pass. AI search does not replace SEO basics; it requires clearer writing, passages that can be quoted, and evidence to support claims.
