Exploding Topics vs Semrush Comparison 2026
Exploding Topics surfaces subjects rising before they peak, from $39 a month for 100 tracked trends, and it is now a Semrush product rather than an independent rival to it.

Exploding Topics answers what is about to matter. Semrush answers what already ranks and what a competitor is doing about it.

Exploding Topics
Trends spotted before they peak
Exploding Topics watches search and social signals and surfaces subjects on the way up, which is a different job from a keyword tool that tells you what is already big. For somebody choosing what to make next, early is the whole value. It is now a Semrush product, and the cheapest plan holds back the CSV export.
Our note
The $39 plan cannot export, so the research stays in their interface. If the point is feeding a content calendar or a spreadsheet, the real entry price is $99.
Semrush
Keyword and competitor research at agency depth
Semrush is the tool an SEO reaches for when they need to know what a competitor ranks for and what it is worth. Position tracking, site audits and keyword gaps are all there, along with newer reporting on how brands surface in AI answers. It costs more than most creators can justify, and the entry plan tracks five sites and 500 keywords.
Why people weigh these two
- Semrush instead of Exploding Topics
- Semrush now owns Exploding Topics and sells its own agency-depth keyword and competitor research separately, starting at $139 a month for the fuller suite.
- Exploding Topics instead of Semrush
- Exploding Topics at $39 surfaces trends before they peak, answering what to cover next rather than how a page competes now.
Which one should you pick
Pick Exploding Topics for deciding what to make next, before the audience is obviously there, at a fraction of Semrush's price. Entrepreneur is $39 a month for 100 tracked trends, though CSV export waits for the $99 Investor tier. Anybody optimising for what people search today, rather than what is about to rise, wants a keyword tool like Semrush instead.
Pick Semrush if traffic comes from search and the competition already has an SEO team, since position tracking, site audits and keyword gaps are what this actually does. SEO is $139 a month, or $117.33 billed annually, for 5 sites and 500 tracked keywords, well past what most creators can justify. If the audience arrives from a feed rather than a search box, this is an expensive way to learn nothing.
Common questions
- Are Exploding Topics and Semrush competitors?
- Not really; Exploding Topics is now a Semrush product, so the two are related rather than rival. They still do different jobs: Exploding Topics spots trends before they peak, and Semrush analyses keywords and competitors at agency depth.
- Is Exploding Topics cheaper than Semrush?
- Considerably: Exploding Topics starts at $39 a month, and Semrush starts at $139, or $117.33 billed annually, described as the most expensive tool in this catalog by some distance. They answer different questions, though, forward-looking trends against current keyword rankings.
- Does Semrush do trend forecasting the way Exploding Topics does?
- Not in the same way; Semrush's strength is competitor keyword research, position tracking and site audits on what is already ranking. Exploding Topics is specifically built to surface subjects on the way up rather than rank what is already large.
- Who should not buy Semrush?
- Anybody whose audience arrives from a feed rather than a search box; its own guidance calls that an expensive way to learn nothing. The entry plan's five-site limit is also the wall most people hit first, well before the $139 monthly price becomes the real problem.
