How did AI assistant search rankings change year over year?
When selecting competitor brands, it is important to check both current and previous rankings. Among the 13 brands, 9 changed ranks compared to one year ago.
When comparing brands with similar search shares, also consider changes in search volume. Among brands with over 1% share and confirmed year-over-year growth, Claude showed the largest increase. Gemini is excluded from growth comparison as its year-over-year change is marked '-'. Claude’s searches increased by +580.5%, moving from 6th to 3rd place in one year. Grok rose from 9th to 4th with +420.1% growth. ChatGPT, ranked first, grew by +67.4%. Perplexity AI declined by 9.7%, dropping from 4th to 5th place.
The reasons behind search volume increases or user expectations cannot be confirmed from this ranking alone. Although Claude and Grok’s search volumes increased, do not assume this reflects demand for specific tasks. The analysis in From Search Signals to Hypotheses examines whether function or task-related keywords are attached to brand names and verifies alignment with potential customer needs.
| Change | Brand | Monthly Average Searches | Year-over-Year Change | Rank (1 Year Ago → Now) |
|---|---|---|---|---|
| Increase | Claude | 3,388,981 | +580.5% | 6 → 3 |
| Increase | Grok | 1,128,907 | +420.1% | 9 → 4 |
| Increase | ChatGPT | 45,187,580 | +67.4% | 1 → 1 |
| Decrease | Perplexity AI | 804,620 | -9.7% | 4 → 5 |
How concentrated is search interest in top brands?
When entering the AI service market or allocating marketing budgets, this share is primarily used to select brands for comparison. Use the search volume gap with top brands as a reference but do not interpret it as differences in sales or required advertising budgets.
A. (114,298 searches, 0.2%), IXIO (27,632 searches, 0.0%), and Clova X (25,510 searches, 0.0%) had lower search shares than the top brands in this tally. However, this result alone does not reveal which brand users think of first.
Deciding whether to advertise as a general AI assistant or emphasize specific tasks or functions should not be based solely on search concentration. For example, marketers should review detailed search terms by task or function, segment advertising message candidates, and design tests comparing costs and conversion rates for each candidate.
How should practitioners apply this ranking data in their work?
Search ranking data serves as a reference for various practical decisions, from marketing campaigns to tool adoption. The way data is read and applied varies by task.
When comparing before and after brand campaigns, check both your brand’s search volume and share within the genre. The 75,824,764 figure here is a monthly average total, so to see monthly changes, check your brand’s and genre’s monthly totals separately. A change in search volume alone does not prove campaign effectiveness or market share within target customers.
When managing search ads, use this ranking to select brand keyword candidates for review. Do not judge ad costs or competition intensity by search volume alone; check the advertising costs for those keywords before running campaigns. Ads using competitor brand keywords should be budgeted by comparing cost per click and conversion rates.
Search trends also guide decisions on partnerships or platform entries. Prioritize integration with top tools and features that attract user attention or consider brands with rapidly growing search volumes as collaboration candidates.
AX managers adopting internal tools should distinguish between brand search share in the domestic market and employee familiarity with tools. This table reflects domestic search interest and does not show which tools employees are accustomed to or training costs after adoption. When promoting Marketing AX, separately verify employee experience and training needs for each candidate tool.
