From SEO to GEO: How AI Search Engines Decide What Content Appears in Answers

Search engines once relied on algorithms that helped users find pages of prioritized links based on their relevance to the keywords in the current query. AI-enhanced search engines have fundamentally changed how algorithms work, providing AI summaries that often answer the user’s query without the user clicking anything on the search results page (zero-click searches).

The goal of any site manager is to get their website to rank across Google, Bing, OpenAI, and Yandex. In this article, we discuss how AI affects search algorithms and the various SEO and GEO factors that help modern search engines decide what content appears in generated answers.

How AI Affects Search Algorithms

To properly adapt your SEO and GEO strategies, you first need to understand how AI has changed the way that modern search engines function. The goal of content visibility was to rank highly on search engine result pages (SERPs) through keyword placement, internal linking, and other SEO-friendly tactics. However, the new goal of modern SEO is to optimize your content so that it is more likely to be in an AI-generated summary.

Many modern search engines provide AI-generated overviews that either answer your query or summarize the most relevant information. Generative Engine Optimization (GEO) is designed to rework your content so it can be easily digested and summarized by the AI systems powering these search engines.

SEO Factors

Keywords

Keywords remain the most fundamental aspect of search engine optimization, and they remain relevant even in the age of AI-driven visibility. Search algorithms will look at the words and phrases included in each user’s query and then find content online that contains the most relevant keywords present in the query. Every industry and niche has specific keywords that must be targeted to attract the right audience and generate quality leads.

Backlinks

Backlinks are another basic SEO factor that still helps AI search engines decide what content to draw from. To put it simply, backlinks are links to your website from other websites. These links are important because they signal both trust and authority, which AI models like to see when filtering results. The better and more respected the website, the higher the quality of each backlink. Great backlinks also help drive referral traffic to your website.

Indexability

For a website’s content to appear in AI answers, the site must be easily indexable. Search engines use bots to crawl through webpages, and your site’s internal links function like a site map so that the bots can progress from one page to another. Various technical issues can mess with a webpage’s indexability, including duplicate content, broken internal links, and redirect loops. If a site cannot be indexed, it will not appear in search results or get organic traffic.

Technical SEO

Technical SEO is one of the most important factors in optimizing your content to appear in AI search results. AI-powered search engines must be able to crawl your website quickly and gather all relevant information for their summaries, so you need to focus on any technical issues that could affect that.

Start by removing content clutter, fixing messy code, and addressing any lagging or slow-loading issues. All of these aspects will also benefit your site’s user experience (UX), because both humans and AI machines need to be able to read your content.

GEO Factors

Structure

GEO can be a bit more complex than SEO, and it often starts with how your site’s content is structured. In this context, structure refers to how readable your content is. Both users and machine models need to be able to easily read and understand what is being said on your site, meaning that the visual organization of each webpage must be clean and consistent.

AI search engines will read your content’s structure through its on-page HTML formatting, meaning that there needs to be a clear organization using headings, bulleted lists, and a general layout. Large language models also tend to like certain structural elements, including clear main topics, subtopics in respective subheadings, FAQs at the bottom of the page, explicit product placements, and other relevant site data.

Schema

Schema markup is a technical factor that heavily influences GEO and refers to how data is structured on your site. While AI must generally interpret structure, schema markup enables your site to speak directly to the large language models powering major search engines. Schema markup also provides vital context about what your site offers, increasing the likelihood of citations.

Authority

AI search engines are also much more likely to include your site’s content in their answers if they consider your brand authoritative. While older search engines focused on keyword placement and a list of links, newer models look for the most thorough, comprehensive answer to each query from a trustworthy source.

The biggest aspect of asserting content authority is prioritizing facts and using high-quality sources. On top of that, each company should work to establish brand authority within its industry while building strategic partnerships and connections with other trusted brands. Backlinks from other authoritative brands also make your site more trustworthy.

Summary

Websites seeking visibility among major movers in search and tech (e.g., Google, Bing, OpenAI, and Yandex) must adapt their content to multiple SEO and GEO factors. AI search engines decide what content appears in their answers based on keyword placement, quality backlinks, site indexability, technical SEO, content structure, data schema, and overall trust and authority. In the age of AI, content must be crawlable, digestible, and summarizable by large language models.
