Step-by-Step Process

- "Discover new keywords" → enter seeds.
- Get volume + competition + bid range.
- Export to CSV.
3. Add Long-Tail Variations
- 3-5 word phrases.
- Lower volume but higher conversion rate.
- Cheaper CPC.
- Easier to rank Quality Score 8-10.
4. Competitor Research

- See keywords they bid on.
- See their ad copy.
- Estimate their spend.
- Find gaps you can exploit.
5. Analyze Search Intent
- Google each keyword, look at top results.
- Are they ads? = competitive but profitable.
- Are they blog posts? = informational intent.
- Are they product pages? = transactional.
6. Group Into Tight Ad Groups
- 10-20 closely-related keywords per ad group.
- Single theme per group.
- Headlines mention the keyword.
- Better Quality Score = lower CPC.
Negative Keywords (Critical)

Building Negative List

Avoid
- 100% broad match — wastes budget on irrelevant.
- 100% exact only — misses long-tail discoveries.

Frequently Asked Questions
Free Google Ads keyword research tool?
Google Keyword Planner (free with any Ads account). Ubersuggest free tier. Both work for beginners.
How many keywords per ad group?
10-20 tightly themed. Quality Score plummets with broader sets. Single-Keyword Ad Groups (SKAGs) controversial — work but high maintenance.
Should I bid on competitor brand names?
Legal in most regions, but risky: trademark complaints, click-fraud retaliation. If doing it: never use their name in ad copy.
Long-tail vs head keywords?
Long-tail usually better CPA + Quality Score. Head terms drive volume but expensive. Most accounts: 70% long-tail / 30% head.
How often update keyword list?
Add negatives weekly. New keywords monthly. Major review every quarter. Search trends shift fast.
