How to Do Keyword Research for SEO (Using Free Tools)

If you're new to SEO, keyword research might sound a little overwhelming—but don’t worry, we’ve got you!

Updated over a week ago

🔹 What Is Keyword Research?

Keyword research is the process of finding out what words or phrases people are typing into Google when they’re looking for products or content like yours. Knowing these keywords helps you:

  • Show up in search results

  • Get more traffic

  • Attract the right visitors who are ready to buy


🛠 Before we start, here are the terms You Should Know (Simple Definitions)

How hard it is to rank on Google for that keyword.

  • A high KD = lots of competition

  • A low KD = easier to rank for (great for new or small websites)

The average number of times a keyword is searched per month.

  • A higher number = more potential traffic

  • But high volume keywords often come with high difficulty

Keywords that don’t have a lot of strong websites competing for them.

  • These are easier to rank for and are great for newer stores

Longer, more specific phrases like:

“eco-friendly dog collars for small breeds”

  • They usually have lower competition

  • Attract more targeted and ready-to-buy visitors

Keywords that show someone is looking to make a purchase.
Examples:

“buy leather dog collar”
“cheap dog collars online”
“best organic dog treats 2025”

  • These are gold for product pages!



✔️Let's begin:

🔹 Step 1: Start with a Topic

Think about a product or category you sell.
Example: If you sell pet items, you could start with something like "dog collars".

🔹 Step 3: Choose the Right Keywords

When starting out, go for:

Use a spreadsheet to organize:

  • Keyword

  • Search volume

  • Difficulty (if available)

  • Notes (e.g., blog topic, product it applies to)


🔹 Step 4: Evaluate & Choose the Best Keywords

Now that you have a list of keyword ideas, how do you know which ones to focus on?

Here’s a simple way to decide:

🟢 Go for keywords that are:

Criteria

Why It’s Good

What to Look For

✅ Low Competition

Easier to rank for

Low KD score or difficulty rating (0–30)

✅ Long-Tail

More specific = more targeted traffic

3–5+ word phrases

✅ Buyer Intent

Brings visitors ready to purchase

Includes words like “buy,” “best,” “cheap,” “online”

✅ Decent Search Volume

Means people are actually searching it

At least 50–100 searches/month (for newer stores)

Example:
Let’s say your spreadsheet has:

  • dog collars → 18,000 searches, high difficulty

  • leather dog collars for small dogs → 500 searches, low difficulty

The second one may bring less traffic, but it’s much easier to rank for and more targeted. So it’s the smarter choice for a newer or smaller site.

✅ Pro Tip: Use a Scoring System

If you want to get fancy, assign each keyword a score (1–5) based on:

  • 🔹 Relevance

  • 🔹 Difficulty

  • 🔹 Search volume

  • 🔹 Buyer intent

Then prioritize the ones with the highest overall score. 👍


🔹 Step 5: Add Keywords to Your Site

  • Product titles and product descriptions(our app will automatically use your keywords in your meta titles, meta descriptions, and alt tags if AutoPilot is enabled) - See our AutoPilot guide
