Google Ads Keyword Research Beginners Guide

Keyword research is the work of finding the words real customers type into Google when they need what you sell. Get this right, and your ads reach people who are ready to act. Get it wrong, and you pay for clicks from people who were never going to buy. This beginner’s guide walks through a simple, repeatable process you can finish in an afternoon.

Start with intent, not volume

Search volume tells you how many people search, but intent tells you why. Someone searching “what is google ads” is learning. Someone searching “google ads management pricing” is comparing services. Someone searching “emergency plumber near me” probably needs help now. For a small budget, the last two types are usually worth more than a huge number of curious visitors.

Write down 10 to 20 problems your customers have, in their words. A bakery might list “birthday cake delivery”, “gluten free cupcakes near me”, and “wedding cake tasting”. A plumber might list “blocked drain”, “boiler repair cost”, and “leaking tap fix”. Those plain phrases are your seed keywords.

Expand, then filter ruthlessly

Put each seed into Google’s Keyword Planner, or simply look at related searches at the bottom of Google results, and note variations. Then filter with three questions: Does this search show buying or booking intent? Can I serve this person well? Can I afford the likely click cost? If the answer to any question is no, leave it out for now. A list of 30 strong keywords beats a list of 300 loose ones.

A worked example

Imagine a local yoga studio with a $600 monthly budget. It targets “beginner yoga classes near me” and “online yoga for beginners”. If the average CPC is $1.20, that budget buys about 500 clicks. At a 3% conversion rate, that is about 15 trial sign-ups, at a CPA of $40. If a trial converts to a $120 monthly membership often enough, that CPA can work. If the studio instead bids on broad “yoga” searches, it may get cheaper clicks but far fewer sign-ups, because many searchers are looking for free videos, not classes.

Match types and negative keywords

Use phrase and exact match for your most important keywords at first, so you control which searches trigger ads. Add negative keywords for searches you do not want, such as “free”, “jobs”, or “DIY” if you sell a paid service. Check the search terms report every few days in the first month. It shows the actual searches that triggered your ads, and it is often the fastest way to find waste.

Your keyword checklist

• Group keywords by topic, with one landing page per group.
• Write ads that include the main keyword and match the landing page promise.
• Set a maximum cost per conversion before you launch, using the Budget Calculator.
• Track keywords in the Keyword Planner and Tracker, and pause keywords with many clicks and no conversions.
