Google Trends now lets you compare up to 400 search terms at once, across 8 groups of up to 50 terms each, up from 125 terms across 5 groups of 25. Barry Schwartz reported the change on Search Engine Roundtable on 3 August 2026, and he found it not through an announcement but by noticing that Google had quietly edited a help document. There is a catch worth knowing before you plan around it: classic explore was not upgraded and still holds the old limits.
What the help document now says
The Google Trends help document previously read: "You can explore multiple search terms in different languages in real time. Compare up to 5 groups of terms at once and up to 25 terms in each group." It now reads: "You can explore multiple search terms in different languages in real time. Compare up to 8 groups of terms at once and up to 50 terms in each group."
That is the entire published basis for the change. Google issued no blog post, no product announcement and no date, so nobody outside Google knows when the limits actually moved. Schwartz spotted a documentation edit, which is a legitimate signal but a different thing from a launch.
Classic explore did not get the upgrade
The same help document carries a note, verbatim: "Note: Classic explore supports comparing 5 groups of terms at once and up to 25 terms in each group." So the old ceiling is still in force there. Schwartz put it plainly, writing on 3 August 2026 that "the classic export has not yet been upgraded to support 220% more search terms but maybe it will in the near future."
This matters more than it sounds. Which interface you open decides which limit you get. If you build a comparison plan around 400 terms and then run it in classic explore, you hit 125 and have to split the work anyway. Whether classic explore will ever be raised, and when, is not stated anywhere in the source.
The 220% figure belongs to Schwartz, not Google
Schwartz described the change as "a 220% increase, if my math is correct". That is his own arithmetic and his own hedge, and it is worth carrying both parts. Google published no percentage, because Google published nothing at all. The numbers you can verify are the ones in the help document: 5 groups to 8, 25 terms per group to 50.
Before and after, in numbers
The table sets the old limits against the new ones, using only figures stated in the Google Trends help document as reported by Search Engine Roundtable on 3 August 2026.
| Limit | Before | After |
|---|---|---|
| Groups of terms compared at once | 5 | 8 |
| Terms in each group | 25 | 50 |
| Total terms in one comparison | 125 | 400 |
| Classic explore | 5 groups, 25 terms each | Unchanged: 5 groups, 25 terms each |
What this means for Thai marketers
The source says nothing about Thailand, and nothing about whether the limit differs by country or language, so the following is reasoning rather than reporting.
Four hundred terms in a single view changes what a comparison is for. A seasonal read across a full product category that previously took four separate charts, stitched together in a spreadsheet with the normalisation quietly broken between them, can now sit in one chart with one scale. For a Thai retailer comparing category demand across a year, or a team sizing a new topic cluster before committing to it, that is a real saving in time and a real reduction in error. It feeds directly into how you scope a content marketing plan, since the comparison you can actually run shapes the categories you choose to cover.
Two cautions, both of them from the source rather than from us. Nothing has been said about whether the underlying data, sampling or export behaviour changed, so treat the numbers exactly as you did before. And check which interface you are in before you build anything on the higher ceiling.
Questions people are asking about the new Google Trends limit
When did Google raise the limit?
The source does not state it. Google published no announcement and no date. Schwartz noticed the help document had been changed and reported it on 3 August 2026, so the only firm date attached to this story is the date it was spotted.
Does the new 400-term limit work in classic explore?
No. The help document says classic explore still supports 5 groups of terms with up to 25 terms in each, which is the old 125-term ceiling. Only the current explore interface carries the 8 groups and 50 terms per group.
Will classic explore be upgraded too?
The source does not state it. Schwartz wrote that it has not yet been upgraded and speculated it might be in the near future, which is his guess rather than anything Google has committed to.
Does the limit differ in Thailand or for Thai-language terms?
The source does not state it. Nothing in the report addresses country or language variation in the limit, so there is no basis for claiming Thai-language comparisons behave differently, and no basis for claiming they behave the same.
Did anything change about the Trends data itself?
The source does not state any change to the data, sampling or export formats. The reported change is to how many terms you may compare at once, nothing more.
This is a small change, and it is worth treating as one. A higher comparison ceiling saves assembly work on keyword and category research; it does not change what the data means. If you want that research turned into a ranking plan, our SEO team in Thailand works from term-level demand data, and an SEO audit is the usual starting point. Schwartz's original write-up is on Search Engine Roundtable.
