Comprehensive SEO Checklist 2026 for Google Search, AI Overviews & AI Mode

Introduction: SEO in Google's AI-Driven Search

Google Search has evolved significantly beyond the traditional ten-blue-links model. Search now includes AI-powered experiences such as AI Overviews and AI Mode, alongside traditional organic results, featured snippets, images, videos, local results, and other search features.

The former Search Generative Experience (SGE) terminology is no longer the appropriate framework for current Google Search. Google has introduced dedicated guidance for AI Overviews and AI Mode, while continuing to emphasize that the fundamentals of SEO remain important for appearing in these experiences.

The goal is therefore not to "optimize for an AI algorithm" through a separate set of secret ranking factors. Instead, websites should make their content:

• Helpful and people-first
• Original and substantially valuable
• Accurate and trustworthy
• Easy for Google to crawl, render, and index
• Clearly structured and understandable
• Supported by appropriate first-hand experience and expertise
• Useful across text, image, video, local, and multimodal search experiences
• Free from practices that violate Google's spam policies

Google's current guidance also makes clear that AI-generated content is not automatically disallowed. The problem occurs when automation or generative AI is used to produce large amounts of unoriginal content primarily to manipulate Search rankings.

The Major Changes in Google Search

Before implementing an SEO strategy, several outdated assumptions should be removed.

1. SGE is no longer the correct terminology

The previous concept of Search Generative Experience has evolved into Google's current AI Search ecosystem, particularly AI Overviews and AI Mode.
SEO strategies should therefore focus on Google's current Search features rather than treating SGE as a separate optimization target.

2. AI Search does not replace traditional SEO

Google's guidance indicates that the same fundamental SEO practices that help content appear in Search also remain relevant to generative AI experiences. There is no guaranteed "AI SEO trick" that makes a page appear in AI Overviews or AI Mode.

Instead, Google needs to be able to:

• Discover the page
• Crawl it
• Render its content
• Understand its subject
• Determine its relevance
• Evaluate its usefulness and quality
• Connect it with appropriate queries and entities

3. Search is increasingly multimodal

Google Search is no longer limited to typed text queries. Users can interact with Search through:

• Text
• Images
• Google Lens
• Circle to Search
• Image uploads
• Videos
• Local searches
• Multimodal queries

In September 2026, Google introduced dedicated Search Console reporting for web multimodal search, including traffic from Lens, Circle to Search, image uploads, and related visual search experiences.

4. Helpful Content is part of Google's core ranking systems

The old "Helpful Content System" should not be treated as a completely separate algorithm. Google incorporated the helpful content system into its core ranking systems in 2024. Therefore, SEO audits should evaluate whether the website consistently produces useful, original, people-first content rather than checking for a standalone "Helpful Content score."

5. Spam policies apply to AI-generated Search experiences

Google explicitly states that its spam policies also apply to generative AI responses in Search. Therefore, attempting to manipulate AI results using scaled, copied, deceptive, or spammy content can create the same fundamental problems as manipulating traditional Search results.

Comprehensive SEO Checklist for Google Search in 2026

1. Build Strong E-E-A-T and Trust

E-E-A-T stands for:

• Experience
• Expertise
• Authoritativeness
• Trustworthiness

E-E-A-T is not itself a single ranking factor. Instead, Google uses a variety of systems and signals that can identify characteristics associated with high-quality, trustworthy content. Google specifically emphasizes that trust is the most important aspect of E-E-A-T, while the importance of experience and expertise varies according to the topic.

How to optimize:

• Clearly identify the content author.
• Provide an author bio where appropriate.
• Demonstrate relevant professional experience or expertise.
• Provide an About page explaining who operates the website.
• Include verifiable credentials when they are genuinely relevant.
• Identify medical, financial, legal, or technical reviewers when appropriate.
• Cite reliable primary or authoritative sources.
• Explain first-hand experience where it materially improves the content.
• Keep factual information accurate and updated.
• Provide transparent contact and business information.
• Make claims that can be independently verified.
• Use original research, testing, examples, photographs, case studies, or data when appropriate.

2. Match Search Intent Before Keywords

Modern SEO should begin with search intent, not simply keyword volume.

Before creating or optimizing a page, determine:

• What is the user trying to accomplish?
• Is the query informational?
• Is the user comparing options?
• Is the user looking for a specific service?
• Is the user ready to purchase?
• Is the query local?
• Does the user need a quick answer or an in-depth explanation?
• Is the user looking for a specific website or entity?

Recommended process:

• Identify the primary query and examine the current SERP.
• Identify the dominant intent and analyze the type of pages ranking.
• Determine what users still need after reading those results.
• Create a page that fulfills the intent better than competing pages.

3. Optimize for AI Overviews and AI Mode

AI Overviews and AI Mode can use information from multiple web sources to generate responses. There is no guaranteed markup, special keyword density, or "AI ranking formula" that guarantees inclusion.

How to optimize:

• Answer the primary question clearly and near the beginning.
• Explain the topic comprehensively with unique information.
• Support important claims with reliable evidence.
• Use clear headings and logical content hierarchy.
• Provide concise definitions where appropriate.
• Use tables and lists when they genuinely improve understanding.
• Include original examples and practical details.

4. Create Original, People-First Content

Google's current guidance strongly emphasizes content created primarily to help people rather than content created primarily to manipulate rankings.

Content quality checklist:

• Does the page provide original information?
• Does it add analysis, experience, testing, or useful interpretation?
• Does it answer the user's actual question?
• Is it substantially more useful than a generic summary?
• Are factual claims accurate and sources reliable?
• Is the content written for humans?

5. Use AI Responsibly

Generative AI can be used as part of a content workflow, but it should not become a system for mass-producing low-value pages.

Safe AI-assisted workflow:

• Use AI for research assistance and brainstorming.
• Verify factual claims manually.
• Add genuine human expertise, first-hand experience, and original examples.
• Review medical, financial, legal, and other YMYL content carefully.
• Remove generic or repetitive sections.
• Avoid mass-publishing near-identical pages.

6. Strengthen Technical SEO

Technical SEO remains the foundation that allows Google to access and understand a website.

Technical checklist:

• Use HTTPS and ensure important pages return HTTP 200 responses.
• Avoid accidental noindex and robots.txt blocking.
• Maintain a valid XML sitemap and use correct canonical URLs.
• Resolve redirect chains and fix broken internal links.
• Prevent crawl traps and ensure JavaScript can be properly rendered.
• Maintain a logical URL structure and check mobile usability.

7. Optimize Core Web Vitals and Page Experience

Core Web Vitals remain relevant, but they should not be treated as a standalone ranking shortcut. Current Core Web Vitals include LCP, INP, and CLS.

• Reduce server response time and optimize images.
• Minimize render-blocking resources.
• Reserve dimensions for images and embeds to reduce layout shifts.
• Avoid intrusive interstitials and make primary content accessible.

8. Use Structured Data Correctly

Structured data can help Google understand page content and can make pages eligible for supported rich search features.

• Follow Google's structured-data guidelines.
• Include required and recommended properties.
• Ensure structured data matches visible content.
• Validate with the Rich Results Test where applicable.

Important 2026 change: Do not build an SEO strategy around FAQ rich results. Google deprecated the FAQ rich-result feature as of May 7, 2026.

9. Build Strong Internal Linking and Information Architecture

Internal linking helps users navigate the site and helps search engines understand relationships between pages.

• Link from authoritative pages to important money pages.
• Use descriptive, natural anchor text.
• Avoid orphan pages and maintain a logical site hierarchy.
• Consolidate competing pages where appropriate.

10. Optimize Images, Video and Visual Search

Search is increasingly multimodal, so visual assets should be treated as part of the content rather than decorative additions.

• Use descriptive filenames and accurate alt text.
• Compress images and use modern formats.
• Provide transcripts and captions for videos.
• Use VideoObject structured data when applicable.

11. Build Authority Through Relevant, Editorially Valuable Links

Backlinks remain useful, but SEO should not be reduced to the number of links acquired. Focus on earning links because the content deserves to be referenced.

• Publish original research and industry data.
• Create unique resources and tools.
• Avoid paid links, link farms, automated link building, and PBNs.

12. Avoid Google's Current Spam Risks

Modern SEO audits should explicitly check Google's spam policies, including Scaled content abuse, Scraping, Cloaking, Doorway abuse, Hidden text/links, Keyword stuffing, and Site reputation abuse.

13. Monitor Site Reputation and Third-Party Content

Publishing third-party content on an established website can create SEO risk when the primary purpose is to exploit the site's existing ranking signals (e.g., Sponsored content, White-label articles, External contributor content).

14. Optimize for Local Search

For local businesses, traditional organic SEO should be combined with local relevance. Maintain consistent business details, optimize Google Business Profile, and create genuinely useful location-specific content rather than mass-producing identical city pages.

15. Optimize for Multimodal Search

Google's search ecosystem increasingly connects text, images, videos, and visual queries. Optimize product images, original photography, infographics, demonstration videos, and diagrams.

16. Use Search Console as a Continuous SEO Feedback System

Monitor Clicks, Impressions, CTR, Average position, Core Web Vitals, Indexing, Sitemaps, Manual actions, Security issues, and Multimodal Search performance. Analyze performance by: Query → Intent → Page → Search feature → Conversion.

17. Analyze AI Search Visibility Without Chasing "AI Scores"

There is no reliable universal "AI SEO score". Instead, monitor whether your website appears for relevant queries, receives impressions for long-tail queries, and provides unique information that other sources do not.

18. Optimize for Entity Understanding and Topical Relationships

Modern Search systems need to understand relationships between People, Organizations, Products, Services, Locations, and Topics. Make these relationships explicit through the site's content and architecture.

19. Prioritize First-Hand Experience

Include information that generic AI-generated summaries cannot easily reproduce: Original photographs, First-hand testing, Real case studies, Original research, Expert commentary, and Practical implementation details.

20. Optimize for Conversions, Not Just Rankings

SEO success should not be measured only by position. Track Qualified organic traffic, Leads, Calls, Form submissions, Purchases, Appointment requests, Revenue, and Conversion rate.

21. Perform Regular Content Audits

Every important website should periodically evaluate existing content to determine whether to Keep, Improve, Consolidate, Redirect, Remove / Noindex, or Refresh pages.

22. Do Not Chase Every Google Algorithm Update

When traffic changes after an update, do not immediately rewrite every page. Identify the affected pages/queries, compare before/after performance, and improve the affected pages systematically.

23. Remove Outdated SEO Tactics

Avoid Keyword stuffing, creating hundreds of AI articles without editorial value, building backlinks in bulk, treating E-E-A-T as a single score, and assuming `llms.txt` provides a ranking benefit.

24. Build a Search Strategy Around Topics, Entities, Intent and Users

Connect four major elements: Search Intent, Topic, Entity, and User Outcome. This produces a stronger strategy than simply assigning one keyword to one page.
