Which one is for you
Pick Exploding Topics if
- Fits if you pick content topics and want ones whose searches are still climbing
- Works for sellers and investors looking for products, markets and startups that are starting to rise
Look elsewhere if
- Pricey if you want forecasts, trending startups or CSV export, which start at $99 a month
- Skip it if you need keyword volumes and difficulty for pages you're writing now
- Not for you if you'd rather not have a Semrush account, as Pro runs through one
- Watch out: the pricing page doesn't say how prices are billed, and a vendor blog says $39 is the yearly rate
- Watch out: TikTok Insights is a separate add-on with no price shown
Pick Semrush if
- Fits if you want research, rank tracking and audits in one account and can pay $117.33 a month or more
- Works for agencies that need keyword data for many countries and compare client sites with competitors
Look elsewhere if
- Pricey if you're one person with one site, at $117.33 a month even yearly, and the trial checks your card with a small charge
- Tight if your team is more than just you, since every extra user is from $45 a month
- Skip it if AI answer tracking is the point, as the SEO plan leaves it out and Starter is $165.17 a month
- Watch out: the API and share of voice need the custom-priced Advanced plan, and scheduled PDF reports are $10 to $20 a month extra
- Watch out: local, content, social and ad tools are separate toolkits with their own prices, and the free plan allows 10 reports a day

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
