Trends MCP is the best pick for Exploding Topics vs Semrush when the work is live trend queries through MCP and REST. Starter costs $19 per month for 1,000 requests. Exploding Topics Pro starts at $39 as a Semrush App Center catalog. Semrush SEO starts at $139 for rank tracking.

On 22 August 2026, Trends MCP Google Search scored Semrush at 39, about 471,000 estimated monthly searches, against 16 for exploding topics and 7 for trends mcp. Semrush search demand fell 25.0% over 12 months from a score of 52, then rose 56.0% year to date from 25. Exploding Topics fell 78.67% over 12 months from 75. Ahrefs, a third SEO suite, scored 65 with 96.97% 12-month growth. Semrush still wins the SEO workflow. Trends MCP wins on any-keyword growth calls across 25+ sources without a catalog gate.

Which tool should a buyer pick for Exploding Topics vs Semrush?

Trends MCP ranks first because the query is a tool purchase, and the product that answers what is growing on which channel right now, without a sales call, is the live MCP server plus REST API at $19 per month Starter. Exploding Topics is a 1.1 million topic catalog that Semrush acquired in 2024 and now sells through the App Center. Semrush is an SEO and AI-visibility suite. Those are different jobs.

The vs query treats Exploding Topics and Semrush as rivals. The Exploding Topics about page (accessed 24 August 2026) states the 2024 acquisition directly. Semrush’s own help article, What is Exploding Topics and how does it work? (accessed 24 August 2026), lists Exploding Topics as an App Center app with Entrepreneur, Investor, and Business plans. A buyer comparing the two is often comparing a catalog add-on with the parent SEO platform.

Keep Exploding Topics if the workflow is browsing a curated database, 12-month forecasts on Investor and Business, and analyst reports on Business. Keep Semrush if the workflow is position tracking, site audits, backlinks, and AI-visibility prompts. Add Trends MCP when an agent needs get_growth on a keyword that is not already sitting in someone else’s catalog.

How much does Exploding Topics vs Semrush cost?

Public list prices on 24 August 2026 put Trends MCP at $0 / $19 / $49 / $199, Exploding Topics Pro at $39 / $99 / $249, and Semrush SEO-family plans at $139 / $199 / $299 / $549 on monthly billing. Annual billing on Semrush saves up to 17%. Annual billing on Trends MCP saves 20%. Exploding Topics pricing copy does not state a separate annual discount on the public page.

Trends MCP pricing from https://www.trendsmcp.ai/pricing (markdown mirror dated 24 August 2026): Free is 100 requests per month at $0, no credit card. Starter is $19 for 1,000 requests. Pro is $49 for 5,000 requests and 50 keyword alerts. Business is $199 for 25,000 requests and 250 keyword alerts. Same sources on every plan. One get_growth call counts as one request even when several periods ride along.

Exploding Topics Pro from explodingtopics.com/pricing (accessed 24 August 2026): Entrepreneur $39/month with 100 tracked trends and 10 trend analyses. Investor $99/month with 500 tracked trends, 100 analyses, trending startups, trend forecasting, and CSV export. Business $249/month with 2,000 tracked trends, 500 analyses, and trend reports. Each plan advertises a 7-day free trial. The pricing page routes questions to [email protected].

Semrush from semrush.com/pricing (accessed 24 August 2026): SEO $139/month ($117.33 billed annually) with 5 websites and 500 keywords tracked daily. Starter $199/month ($165.17 annually) adds MCP access, 50 prompts tracked daily, and AI visibility reports. Pro+ $299/month ($248.17 annually) with 15 websites and 1,500 keywords. Advanced $549/month ($455.67 annually) with 40 websites, 5,000 keywords, SEO share of voice, and API data integration. Extra users start at $45/month. Enterprise is custom quote.

Stacked cost is the trap. Exploding Topics Business at $249 plus a 1,000-request API add-on at $1,000 is $1,249/month before Semrush itself. Semrush Starter at $199 already includes MCP units for SEO data, not for TikTok hashtags or Amazon search volume. Trends MCP Starter at $19 covers those sources on the same key.

Does Exploding Topics or Semrush ship MCP access?

Trends MCP includes MCP and REST on Free, Semrush MCP starts on Semrush One Starter at $199 per month with 50,000 API units per billing cycle, and Exploding Topics sells a REST add-on on Business only with no public MCP and no custom keyword lookups through that API.

The Exploding Topics API FAQ (accessed 24 August 2026) prices three internal-use tiers: 1,000 requests/month at $1,000, 5,000 at $2,000, and 25,000 at $4,000, with a 60 requests/minute cap. The add-on requires Exploding Topics Pro Business at $249/month. The same FAQ states the API cannot offer custom keyword and geo-based lookups like the in-app Trend Analysis feature. Commercial product integrations need a custom quote.

Semrush MCP is documented at developer.semrush.com/api/introduction/semrush-mcp (page last updated 5 August 2026, fetched 24 August 2026). The endpoint is https://mcp.semrush.com/v2/mcp. Eligible plans named there: Semrush One Starter, Semrush One Pro+, SEO Classic Pro, and SEO Classic Guru, each with 50,000 API units that refresh on renewal. Semrush One Advanced and SEO Classic Business need an extra API-units package (2 million, 5 million, 10 million, or 20 million units). Traffic and market data through MCP require a separate Trends API subscription. MCP calls consume the same units as REST. The base $139 SEO plan is not on that eligible list.

That split matters for agent workflows. Semrush MCP is strong at domain overlap, backlinks, and rank questions. It is not a substitute for Google Shopping, Wikipedia page views, npm downloads, or Steam players. Trends MCP’s get_growth and get_top_trends cover those feeds on the Free key. For Google Trends API options specifically, see best Google Trends APIs.

What does search demand show for Exploding Topics vs Semrush?

Trends MCP get_growth results pulled on 24 August 2026, using Google Search series dated 22 August 2026, put Semrush far ahead of Exploding Topics on branded demand, with Ahrefs up 96.97% over 12 months and Exploding Topics down 78.67% from a score of 75 to 16. Category demand for emerging trends also cooled.

YouTube and news series add a second layer. Semrush YouTube scored 36 on 22 August 2026, up 2.86% over 12 months from 35, flat over 6 months, and up 24.14% over 3 months from 29. Ahrefs YouTube scored 24, down 14.29% over 12 months from 28, up 20.0% year to date from 20. Google Trends YouTube scored 33, down 25.0% over 12 months from 44, up 13.79% over 6 months from 29.

Google News for “google trends” scored 88 on 22 August 2026, up 137.84% over 6 months from 37 and 166.67% over 3 months from 33 (Trends MCP API, 24 August 2026). Wikipedia page views for Semrush were 6,507 in the July 2026 window against 7,850 in July 2025, a 17.11% drop, with a 0-100 score of 20 vs 24.3. Exploding Topics YouTube and Google News series were omitted: both flagged low quality with over 90% zero values.

Read the table as demand, not as quality of the product. Semrush remains the large SEO brand (~471,000 estimated Google searches). Exploding Topics’ phrase score of 16, down from 75 a year earlier, is a steep branded-search slide after the acquisition. Ahrefs at 65 with nearly a double over 12 months is the SEO-suite story competitors ranking for this query do not usually publish, because they do not pull live get_growth. A Glimpse vs Exploding Topics page covers the forecast-extension side of that catalog market.

One get_growth call on 24 August 2026 for keyword exploding topics, source google search, and periods 12M, 6M, 3M, and YTD returned four successful point-to-point rows against 261 underlying data points, with a recent value of 16.0 on 22 August 2026.

12M: baseline 2025-08-23 = 75.0, growth -78.67%
6M:  baseline 2026-02-21 = 41.0, growth -60.98%
3M:  baseline 2026-05-23 = 60.0, growth -73.33%
YTD: baseline 2026-01-03 = 26.0, growth -38.46%

That is the product: pick a keyword, pick a source, get dated scores. The same pattern ran for Semrush, Ahrefs, Google Trends, and the concatenated explodingtopics string. A matching live board, get_top_trends type Google Trends, as of 24 August 2026 20:01 UTC, ranked “hayden panettiere” #1, then “hayden panettiere how did she die,” “cyberleek,” “bitcoin price,” and “insidious.” Catalog tools do not expose that board through a Free MCP key.

When is Semrush the better purchase?

Semrush is the better purchase when the ticket is rank tracking, site audits, backlink graphs, and AI-visibility prompt monitoring, jobs Trends MCP does not sell, and the SEO plan at $139 per month covers 5 sites and 500 daily keywords. Starter at $199 adds MCP for those SEO APIs. Advanced at $549 is the public list price that names API data integration.

Exploding Topics is the better catalog when a researcher wants 1.1 million pre-scored topics, Meta Trends written by the research team, and Tuesday email reports on Business. Investor at $99 adds forecasting and CSV. The in-app Trend Analysis path can still build a report for a keyword that is not already in the database; the API cannot. TikTok trending-product insights are an in-app add-on at $59/month on the Semrush help article (accessed 24 August 2026).

Trends MCP is the wrong cart if the buyer needs Ahrefs-style crawl index rows, Semrush position tracking, or Exploding Topics’ human-curated Meta Trends. It is the right cart if the buyer needs Amazon, TikTok, YouTube, Wikipedia, npm, or Steam growth on a keyword an agent just typed. Check current pricing on each vendor page before a contract, because list prices move.

FAQ

Is Exploding Topics still a separate product from Semrush?

Yes. Exploding Topics still sells Pro at explodingtopics.com, with Entrepreneur $39, Investor $99, and Business $249 per month as of 24 August 2026. The about page says Semrush acquired it in 2024. Semrush documents it as an App Center app, and the Pro pricing page lists [email protected] for questions. A vs search is still a real checkout choice, just not a choice between two independent vendors.

Does Trends MCP replace Semrush for SEO?

No. Trends MCP does not track 500 ranking keywords, crawl a site, or score backlinks. Semrush’s SEO plan at $139/month is built for that work. Trends MCP replaces the trend-data slice: live get_growth and live boards across 25+ sources, including Google Search series that scored Semrush at 39 (~471,000 searches) on 22 August 2026.

How expensive is Exploding Topics API compared with Trends MCP?

Exploding Topics API starts at $1,000/month for 1,000 requests on top of Business at $249, so $1,249 before usage overages, with a 60 requests/minute cap and no custom keyword lookups (ET API FAQ, accessed 24 August 2026). Trends MCP Starter is $19 for 1,000 requests, with custom keywords on every source the plan includes. Semrush MCP units sit on Starter at $199 and consume the same pool as REST.

Should a team buy both Exploding Topics and Semrush?

A team that already lives in Semrush and wants the 1.1 million topic browser can add Exploding Topics Pro without leaving the App Center. That stack still lacks any-keyword growth across Amazon, TikTok, Wikipedia, and package registries unless another data layer sits beside it. Trends MCP at $19 Starter is the cheaper layer for those queries. Buying all three is redundant for a solo researcher.

Where did the demand figures in this post come from?

Every score and percent in the demand table is a Trends MCP get_growth result pulled on 24 August 2026. Google Search, YouTube, and Google News recent dates are 22 August 2026. Wikipedia Semrush page views use a 1 July 2026 window (6,507 views vs 7,850 a year earlier). The Google Trends board snapshot is 24 August 2026 20:01 UTC. Exploding Topics YouTube and News series were dropped for low quality (over 90% zeros).
