- Semrush combines keyword, competitor, audit, backlink, content, and paid-search work.

Free Google Ads Negative Keywords Generator is the better choice when all you need is a first exclusion list for a Google Search campaign. Semrush is the better choice when search marketing is ongoing work involving keyword research, competitor analysis, technical audits, backlinks, content work, and reporting. The free utility creates suggestions from a campaign’s keyword, industry, market, and match type, then leaves the advertiser to judge and apply them. Semrush provides a wider research environment, but its price and onboarding effort make little sense for a one-off hygiene task. Start with the free generator for an initial list and actual query data for validation. Pay for Semrush only if recurring research and reporting has a real owner and regular decision attached to it. The practical mistake is treating a generic starting list as account analysis, or treating a large research platform as a way to avoid a short manual review.
The tools at a glance
Free Google Ads Negative Keywords Generator
Free Google Search utility for turning campaign context into a reviewable first negative-keyword list
The utility starts with a main keyword, product, or service, then asks for an industry and Global or India setting. It formats potential exclusions as broad, phrase, or exact negatives and allows a copy or download handoff. That is enough for a small advertiser setting up a campaign.
Its two-list output keeps ambiguous terms in context. Employment and learning intent may be likely exclusions, while free, cheap, course, training, guide, PDF, and download need a business decision. A training provider should not inherit the exclusions a local repair business would use.
It is not keyword-research software or a replacement for account analysis. No Google Ads login, Search Terms Report import, scheduled update, or automated upload is published. Use it to form a hypothesis, then test that hypothesis against campaign structure and real search-query data.

Semrush
Broad search-marketing platform for keyword, competitor, technical, backlink, content, reporting, and AI visibility work
Semrush is a broad search-marketing platform rather than a negative-keyword generator. Its reviewed profile covers keyword research, competitor benchmarking, technical audits, backlink analysis, content optimization, paid-search intelligence, and reporting. That range matters when research is recurring work.
The free tier provides limited access with 10 searches per day, while SEO Toolkit is listed from €134 per month or €112.52 per month billed annually. It can support ongoing audits and agency reporting with branded PDFs and client-specific dashboards, which are different operating jobs from building a starter exclusion list.
AI visibility tracking is separately priced: AI Visibility Toolkit is listed at $99 per month per domain with 25 custom prompts, while Semrush One Starter begins at €190 per month or €158.40 per month billed annually. Do not buy that breadth merely to avoid reviewing a negative list.
