Is Classic SEO Really All You Need to Rank in AI Search?

Bing has just clarified its position on optimization for AI-powered search engines: SEO fundamentals remain the cornerstone. This official statement puts an end to speculation about potential revolutionary new practices to adopt for generative AI.

The message is clear: no technical revolution, but rather a rigorous application of existing best practices. Content must first be properly crawled and indexed according to traditional rules before having any chance of appearing in AI-generated responses.

Three technical elements are particularly highlighted by Bing:

• XML sitemaps: still essential for signaling your pages to search engines
• The lastmod field: considered crucial by Bing for identifying content updates
• IndexNow: instant notification technology to accelerate the indexing of new content
• Classic crawling and indexing: no shortcuts possible, the foundations must be solid

This approach is also validated by Google, suggesting an industry consensus on the continuity of SEO practices for the AI Search era.

This statement is perfectly consistent with what we've been observing in the field since the rollout of SGE and AI features in search results. Content that appears in generative responses consistently comes from pages that are already well-indexed and positioned in classic results.

However, this statement requires nuance: while classic SEO is necessary, it's not always sufficient. We've found that certain types of content are favored by AI: clear structures with hierarchical headings, direct answers to questions, verifiable factual data, and especially strong topical authority.

The Bing-Google convergence on this topic suggests that we won't see a fragmentation of SEO practices across search engines. This simplifies strategy: optimizing properly for fundamentals remains the best investment, but technical execution must be flawless.

• Audit your XML sitemaps: verify they're up to date, properly formatted, and submitted in Google and Bing Search Consoles
• Implement or fix the lastmod field in your sitemaps: ensure it reflects the actual modification dates of your pages
• Activate IndexNow on your site: this free technology significantly accelerates the indexing of your new content and updates
• Optimize your crawl budget: eliminate unnecessary pages, fix 404 errors, improve loading speed
• Structure your content carefully: use a clear heading hierarchy (H1, H2, H3), lists, and direct answers to questions
• Keep your content up to date: AI favors recent and reliable information, regularly update your important pages
• Strengthen your topical authority: create comprehensive and interconnected content on your areas of expertise
• Monitor your indexing: use coverage reports in Search Consoles to quickly detect issues

These technical optimizations, though based on established principles, require advanced expertise and regular monitoring to be effective. Proper implementation of IndexNow, optimal sitemap management with lastmod, and orchestration of a content freshness strategy demand cross-functional skills combining technical knowledge, development, and editorial strategy.

For companies looking to maximize their visibility in this new AI Search era without diverting their teams from their core business, support from a specialized SEO agency ensures rigorous implementation of these best practices, tailored to the specifics of each site and industry sector.
