What Is Keyword Bidding? A Beginner’s Step-by-Step Guide

892 views

Keyword bidding is when we set how much we are ready to pay for our search ads to reach people. The goal can be to get more clicks, more visitors, or more sales.

Let’s say we are selling yoga mats and we want people to visit our website. We place a bid — this is the amount we agree to pay if someone clicks on our ad after seeing it in search results.

How Does the Keyword Bidding Process Work?

When people search on Google, ads don’t just appear by chance.

Behind the scenes, there’s a small auction that happens very fast.

Here’s how it works:

We pick keywords that match our product or service.
We set our bid — how much we’re willing to pay.
When someone searches using those keywords, Google runs an auction.
Google shows ads based on bids and other factors.
We may pay for each click, view, or sale, depending on the plan we choose.

But our ad position is not only about the money.

Google also checks:

Where and when the search is made
If our ad and page are helpful and match the search
If our ad score meets Google’s minimum requirement

This means even if we don’t pay the most, we can still win if our ad is more useful.

What Are the Main Keyword Bidding Strategies?

Google gives us two types of bidding: manual and automated.

Manual bidding lets us decide how much to pay.
Automated bidding uses Google’s system to choose bids for us, based on our goals.

Types of Automated Bidding

Based on what we want to achieve, we can choose different automated plans:

Maximize Clicks – Get as many clicks as possible for our budget
Maximize Conversions – Get the most sales or signups within our budget
Maximize Conversion Value – Get the best value from all sales or actions
Target CPA (Cost per Action) – Get the most results at the average cost we choose
Target ROAS (Return on Ad Spend) – Get good returns based on how much we spend
Target Impression Share – Make sure our ad shows at the top or in a certain place on the page

We may also hear the term Smart Bidding. This is part of automated bidding. It uses smart tools to get more sales or better value.

How to Start Keyword Bidding

To start keyword bidding, we need to make a Google Ads account. We can make one easily from the Google Ads website. Google also has a guide to help us set it up.

Once our account is ready, we can follow these steps:

1. Choose the Right Keywords

We should pick keywords that people search for and that match what we are offering. This helps our ads reach the right people. Google Ads has a tool called Keyword Planner.

We can use it to find new keywords. Just go to Keyword Planner and type words related to our product or service.

It will show us keyword ideas and details like:

Average monthly searches – how many people search for that word each month
Competition – how many others are also using that keyword in their ads
Top of page bid – the low and high price we might pay per click to appear on top

We can also use Semrush’s Keyword Magic Tool for better keyword data. In this tool, we type a general word, choose a location, and hit “Search.” We’ll see more keyword ideas and these numbers:

Search volume – how many searches the word gets each month
CPC (Cost per click) – average price paid when someone clicks the ad
Competition score – how hard it is to rank for that word (from 0 to 1.00)
Intent – what the searcher wants (to learn, buy, or compare products)

When picking keywords, we should:

Choose words that match what we are selling
Pick words that show someone is ready to take action (like “buy red shoes”)
Balance between high searches and how hard it is to rank
Use CPC as a hint – high CPC means the keyword may be important, but we can start low

2. Set Up Your Campaign in Google Ads

When we are ready, we can start a campaign in Google Ads.

First, we choose our goal and the type of campaign (like “Search”).

This will also decide what bidding choices we’ll see next.

We follow the steps on screen to set up the basics. Then we come to the bidding section, where we choose what matters most: clicks, conversions, or getting more views.

Here are some options:

For more website visits, choose Maximize Clicks
For more sales or leads, choose Maximize Conversions or Target CPA
For bigger sales, choose Maximize Conversion Value or Target ROAS
For better visibility, choose Target Impression Share

3. Launch and Monitor Your Campaign

Once our ad is live, we should check how it’s doing. The things we look at will depend on our goal. Here are a few examples:

If we want leads but don’t get many conversions: stop weak keywords and try better ad text or landing pages
If we want website visits but no one sees our ad: raise our bids or try better keywords
If we get conversions but our budget runs out fast: improve ad quality and landing pages to save money
If a keyword works well but gets few views: raise the bid a little to show it more

There’s no perfect plan, but checking often helps us improve.
