Keyword research for paid search plays by different rules than SEO. You're not trying to rank organically over months — you're deciding, in real time, which exact phrases are worth paying for every time someone clicks. Get the keyword list wrong and you're not losing rankings, you're losing budget.
Why PPC Keyword Research Is Different
Every keyword you bid on has a real, immediate cost. Organic keyword research can afford to be broad and exploratory; PPC keyword research has to be ruthlessly filtered by commercial intent, because a poorly chosen keyword doesn't just underperform — it actively drains spend on clicks that were never going to convert.
A solid PPC keyword list should:
- Prioritize transactional and commercial-intent phrases over informational ones
- Separate keywords by match type (exact, phrase, broad) rather than lumping them together
- Include a negative keyword list from day one, not as an afterthought
- Get reviewed against actual search term reports regularly, not set once and left alone
A Simple Framework
- Build a seed list from your products, services, and how customers describe them
- Filter aggressively for commercial or transactional intent
- Assign match types deliberately based on how tightly you want to control spend
- Launch, then mine the search term report weekly for both winners and wasted spend
> Tip: Your search term report — the actual queries that triggered your ads — is a better keyword research source than any tool, because it's showing you real buyer behavior instead of a prediction.
Example
Before: Bidding broadly on "coffee maker," burning budget on clicks from people researching how coffee makers work.
After: Bidding on "buy coffee maker under $100" with exact and phrase match, paired with negative keywords like "how," "diy," and "repair" to filter out non-buyers.
Common Mistakes
- Treating PPC keyword research the same as organic keyword research
- Ignoring match types and letting broad match spend without limits
- Never reviewing the search term report to catch irrelevant traffic
- Chasing high-volume terms instead of high-intent ones

In paid search, the keyword list isn't a wish list — it's a budget decision, one term at a time.
