SEO Keyword Research for Mom Bloggers (6 Free Tools That Actually Work)

I wasted my first 6 months blogging by writing whatever I felt like. My posts went nowhere. Then I learned keyword research and my next 10 posts each brought in 500-2,000 monthly visitors. Same writing skill. Different topic selection. Massive results.

This guide walks you through SEO keyword research using only free tools. No Ahrefs, no Semrush, no $99/month subscriptions. Just the actual workflow I use today.

📌 Key Takeaway: According to Backlinko’s 2024 SEO research, 91% of pages get zero traffic from Google — almost always because the topic was not researched first. Bloggers who do basic keyword research see 4-7x more traffic than those who do not, with no extra writing effort. This guide shows the free 6-tool workflow that works. For SEO basics, see my SEO basics for mom bloggers guide.

The 6 Free Tools You Need

The 5-Step Keyword Research Workflow

Step 1: Brain-Dump 20 Seed Keywords (5 min)

Open a Notion page or notebook. Write 20 phrases moms in your niche search. Examples for “postpartum recovery” niche:

• postpartum essentials
• postpartum belly
• postpartum hair loss
• when does postpartum bleeding stop
• postpartum depression signs
• C-section recovery
• breast milk supply
• postpartum exercise
• postpartum diet
• postpartum sex after birth

These are your starting “seed” keywords.

Step 2: Expand Each Seed (10 min)

Take each seed keyword. Go to Google search bar and type it slowly. Read the autocomplete suggestions — these are real searches Google has data on.

Example: “postpartum hair loss” autocomplete might show:

• postpartum hair loss when does it stop
• postpartum hair loss vitamins
• postpartum hair loss male pattern
• postpartum hair loss natural remedies

Each suggestion is a separate blog post idea.

Now scroll to the bottom of the search results page → “Related searches”. More keyword ideas.

For an even bigger list, click the “People also ask” boxes — Google literally tells you what readers also want answered.

Step 3: Check Search Volume (10 min)

For each promising keyword, check actual search volume in Google Keyword Planner:

1. Sign up for free Google Ads account (no credit card needed for keyword planner only)
2. Go to Tools → Keyword Planner → Discover new keywords
3. Paste your keyword list
4. Filter by country (US for global English audience)

What to look for:

Step 4: Validate with Real Search (10 min)

Take your top 5 keywords. Search each on Google. Look at the first page results.

Green flags (you can compete):

• Results are mostly small/medium blogs
• Multiple results are weak (thin content, old dates)
• “People also ask” suggests Google wants more content

Red flags (skip this keyword):

• First page is all Wikipedia, WebMD, Mayo Clinic, Healthline, Forbes
• All results are paid product pages
• Results are 10+ year old established authorities

Step 5: Use Google Trends (5 min)

Last check. Search the keyword in trends.google.com:

• Steady or rising trend over 5 years → green light
• Declining trend → skip
• Seasonal trend (e.g., “back to school”) → write with timing in mind

Long-Tail Keywords Are Your Friend

A “long-tail” keyword is 4+ words specific to a problem. Examples:

❌ Too broad: “baby sleep” (search vol: 165,000, almost impossible to rank) ✅ Long-tail: “4 month sleep regression breastfeeding” (search vol: 2,400, much easier)

Long-tail wins because:

1. Less competition
2. Higher intent (specific = ready to act)
3. Easier to satisfy reader’s exact need

External authority: According to Ahrefs’s 2024 study, 70% of all Google searches are long-tail keywords, but only 6% of bloggers target them.

My Personal Process (Real Example)

When I planned this Pinterest SEO article (Pinterest SEO 2026), here is what I did:

1. Seed: “Pinterest SEO”
2. Expanded (Google autocomplete): Pinterest SEO 2026, Pinterest SEO ranking factors, Pinterest SEO without followers, Pinterest SEO algorithm
3. Volume check (Keyword Planner):
   • “Pinterest SEO 2026” — 880/mo, low competition
   • “Pinterest SEO without followers” — 320/mo, very low competition
4. Validation: First page of “Pinterest SEO 2026” was mostly outdated 2022 posts → opportunity!
5. Picked: “Pinterest SEO 2026” as primary, “rank pins without followers” as secondary keyword

Result: Article that targets a real query with low competition.

Tools to Avoid (Save Your Money)

• Random “free keyword tools” via Pinterest/blog posts: 80% give fake data
• Paid keyword tools at this stage: Wait until 50K+ monthly pageviews
• “AI keyword research” services: Mostly the same data dressed up
