Key takeaways from ZDNET

AI-driven visits rose 66 percent during 2025 yet still represent under 0.15 percent of overall site traffic.
Citations in AI responses can expand brand exposure even when direct clicks remain limited.
Specific adjustments can raise the likelihood of appearing in AI-generated answers.

Organic search referrals may decline even when rankings stay steady. This shift does not signal the end of established SEO practices. Nor does it require treating AI platforms as an opaque system that cannot be influenced.

Core ranking factors such as external links, site authority, fast load times, and strong content continue to hold value. AI systems simply weigh these signals in new ways that can prove advantageous or limiting depending on execution.

High-quality material sometimes receives mentions from AI tools despite modest domain authority scores. At the same time, many users receive complete answers inside the AI interface, reducing the need to visit source sites.

The upside is greater potential for brand recognition through citations alone. Audiences may become familiar with a resource without generating measurable referral traffic.

This overview outlines steps to secure additional AI citations while preserving traditional optimization efforts. It also covers affordable methods for tracking visibility across AI platforms.

Extent of change in search behavior

Semrush examined more than 50,000 sites and reported a 66 percent increase in AI-sourced traffic for 2025 versus the prior year. Even so, AI referrals remain below 0.15 percent of total visits.

These figures indicate that AI platforms capture substantial search volume yet rarely forward users onward. Services such as ChatGPT, Perplexity, and Google Gemini often function as both starting point and endpoint.

Many sites optimized for conventional search now see reduced priority from AI systems. Traditional engines favored extensive content libraries and topical authority. AI models prioritize concise, direct answers to specific questions while still valuing authority.

AI engines also benefit from targeted files beyond standard robots.txt and sitemaps. A dedicated llms.txt file can assist agents that crawl site content.

These factors combine to affect traffic and visibility. Practical solutions exist for each challenge.

Methods to verify AI citations

Several approaches exist for measuring AI search presence, scaled to available time and budget.

Enter 10 to 15 relevant questions into ChatGPT, Perplexity, or Google AI Mode and record which sources appear. This approach requires no cost and minimal effort.
Free tools such as HubSpot AEO Grader deliver quick assessments of brand presence within AI results.
Google Analytics filters can isolate referrals from chatgpt.com, perplexity.ai, and gemini.google.com. Tracking these over months reveals trends in performance.
After free options are exhausted, paid platforms such as Semrush One or Otterly.AI start at approximately 29 dollars per month.

Factors that secure AI citations

Research from Princeton, Georgia Tech, and the Allen Institute for AI presented at the 2024 KDD Conference tested nine visibility tactics across 10,000 queries and recorded gains up to 40 percent. Effective practices include the following:

Review robots.txt to ensure AI crawlers including GPTBot, OAI-SearchBot, PerplexityBot, ClaudeBot, and Google-Extended are not blocked. Default settings in some content systems can hinder visibility.
AI systems favor self-contained passages. Begin each section with a clear, standalone sentence that states the main point before adding supporting detail.
Include specific figures and references to strengthen credibility. Unsupported claims tend to receive lower priority during model verification.
Place an llms.txt file in the site root directory. This low-effort step follows guidance from Answer.AI though broader adoption remains limited.
Extend brand presence to external channels. LLMs draw from varied sources such as video platforms and discussion forums, so active social profiles increase the chance of inclusion.

Perspective on AI search optimization

Semrush findings highlight considerable confusion surrounding AI search and SEO. While referral traffic has decreased, the volume of clicks forwarded by AI tools falls short of some projections. Citations still deliver value through increased brand awareness even without direct visits.

Teams already invested in conventional SEO possess the necessary data from platforms such as Semrush or Ahrefs to begin AI optimization. Specialized analytics tools exist for those requiring deeper insight, yet they are not essential for every organization. The fundamental goal of producing helpful content remains unchanged, though AI systems apply distinct criteria when assembling responses.
