Claude stamps 2026 onto "best X" search queries

Claude rewrites some web search queries before issuing them, appending the current year to commercial comparison strings so that 'best CRM for startups' goes out as 'best CRM for startups 2026'. The pattern comes from a research note published by Canonry on April 30, 2026, based on a category sample of subqueries and the strings Claude actually sent to search.

At a glance

• The rewrite showed up consistently on commercial and comparison queries: 'best collaboration tools for remote teams' and 'best running shoes' both went out to search with 2026 attached to the string.
• Advice queries such as 'how to choose a therapist', local service queries such as 'best plumber near me' and cost estimate queries such as 'home renovation cost estimate' carried no year at all.
• Canonry's guidance splits a corpus by category: year stamps in the H1, headings and dateModified on comparison pages, and no year in the title on how-to, local service and cost pages.

The finding lands on a layer that most content planning still treats as passive. If the retrieval step edits the query before it ever reaches an index, then the page matching the rewritten string, not the typed one, appears to hold the advantage. That turns year stamping into a targeting decision rather than a cosmetic one, and it likely cuts both ways: the same stamp that helps a comparison page ages a how-to article without buying any retrieval benefit.

Three commercial queries came back with 2026 appended

The note lists three examples on the appended side. 'best CRM for startups' was issued as 'best CRM for startups 2026', 'best collaboration tools for remote teams' as 'best collaboration tools for remote teams 2026', and 'best running shoes' as 'best running shoes 2026'. Canonry describes the pattern as consistent enough to act on.

The study was led by Canonry researcher Alejo Garcia, who sampled subqueries across categories and inspected the strings Claude issued rather than the strings users typed. The note was written up by Arber Xhindoli and published on April 30, 2026 as a research note from the team.

Advice, local and cost queries went out without a year

Three categories showed no year in the issued string. Advice and decision queries such as 'how to choose a therapist' and 'how to find a specialist doctor' stayed as typed. So did local service queries, including 'best plumber near me' and 'home cleaning services near me', and cost estimate queries such as 'home renovation cost estimate'.

Canonry frames the split by intent: when the answer is meant to be evergreen advice, no year is added, and when the answer is a list that should be current, the year goes in. The 'best' prefix on its own does not trigger the rewrite, since the local plumber query stayed unchanged.

Canonry recommends year stamps in the H1, headings and dateModified

For commercial, comparison and 'best X' pages, the note recommends putting the current year in the H1, in section headings and in dateModified on Article or BlogPosting JSON-LD, then refreshing on a real cadence so the date stays honest rather than decorative.

For advice, how-to, local service and cost estimate pages the recommendation reverses: keep the year out of the title and use dateModified for trust instead of stuffing a year into the H1. Canonry says a title claiming 'best X 2026' over 2024 content is a worse match than a page claiming no year at all.

What the note leaves unmeasured

The note does not say how often Claude rewrites within each category, how large the sample was, or whether the behaviour differs between the Claude app, Claude Code and the API. It also does not state whether the rewrite is model behaviour or a property of the search tool. Canonry's prescribed next step for publishers is a category-by-category audit of the corpus rather than a blanket year stamp.
