Start with what the business sells and who should buy it. Google Keyword Planner gives you a first-party starting point; competitor and SEO research tools can add context when you have a specific question. These four candidates serve different research jobs. You do not need all four to build a useful campaign brief.
Google Keyword Planner helps you turn a product, service or website into a shortlist of Search campaign keywords. It provides search estimates and forecasts inside Google Ads. Start here when you need to understand demand before deciding how to structure a campaign.
Consider it for
PPC specialists planning Google Search campaigns, especially when a first-party starting point is enough.
Before you commit
An estimate is not a sales forecast. Match the location and language to the business, then review intent yourself. Google requires completed account setup, including billing details, for basic keyword suggestions.
Semrush combines several research toolkits. Its advertising tools help investigate competitor search advertising and build keyword ideas. It is a candidate when your research needs to connect paid search with a broader view of a market.
Consider it for
Teams researching competitors and coordinating paid search with wider search marketing.
Before you commit
Competitor data is research evidence, not access to their ad account. Check coverage for your country and which toolkit includes the reports you need before subscribing.
SpyFu focuses on competitor search research, including PPC keywords and advertising history. Use it to investigate how another business presents an offer and to find ideas for your own research list.
Consider it for
Advertisers who want a focused competitor-research step before writing ads or expanding keywords.
Before you commit
Observed advertising does not tell you whether it was profitable. Confirm the database covers your target market and avoid copying a competitor’s structure without understanding your own economics.
KWFinder is Mangools’ keyword research tool. It brings keyword suggestions, search-volume information and search-result analysis together. It can support a PPC research shortlist, although its SEO difficulty score answers a different question from paid-search competition.
Consider it for
Specialists who want keyword exploration alongside an SEO view of the search results.
Before you commit
Do not use organic keyword difficulty as a prediction of Google Ads costs or profitability. Check your required location and lookup limits.
