SEO Plural or Singular Keywords: Which Should You Use?

Let’s be honest: if you’ve ever stared at a blinking cursor, wondering whether to optimize for “cat” or “cats,” you’re not alone. The singular vs plural keywords SEO debate is the kind of thing that keeps digital marketers up at night — right after they’ve finished their third cup of coffee and realized their lunch break was just a myth. So, let’s break down the quirks, facts, and best practices around SEO keywords singular vs. plural, and see how you can use this knowledge (and maybe our AI-powered platform at bloggingmachine.io) to make your content work harder than you do on a Monday morning.

Why Does Singular vs Plural Matter in SEO?

You’d think Google would just lump “shoe” and “shoes” together, right? Not quite. The difference between keywords singular plural isn’t just a matter of grammar — it’s about search intent, user behavior, and, yes, your bottom line.

• Singular keywords often attract users looking for definitions, explanations, or general information. Think: “What is a blog?”
• Plural keywords usually signal someone’s ready to compare, shop, or dive into a list. For example: “best blogs for small business.”

And here’s the kicker: Google’s algorithm is smart enough to know the difference. In about 50% of cases, search results for singular vs plural SEO keywords share 7–9 URLs, and in 5% of cases, they’re identical. But for the other half? The results can be wildly different, especially for commercial queries.

The Data: Search Volume and User Intent

Let’s get nerdy for a second (don’t worry, we’ll keep it light). According to industry research:

• Plural keywords often have higher search volumes for commercial or product-related queries. For example, “laptops” gets more searches than “laptop” when people are shopping.
• Singular keywords can dominate for informational or definition-based queries. “SEO” might be searched more by people wanting to know what it is, while “SEOs” (as in professionals) is a different ballgame.

So, before you pick a side in the SEO keywords plural singular debate, check the data. Tools like Google Keyword Planner, Ahrefs, or SEMrush can show you which version gets more love from searchers.

Google’s Take: Algorithm Preferences

Here’s a fun fact: Google doesn’t always treat singular and plural the same. Sometimes, the search engine overlords show similar results for both, but often, they tailor the SERPs (search engine results pages) based on what they think the user wants.

• Informational intent? Singular wins.
• Comparison or shopping intent? Plural takes the cake.

A “SERP Similarity Analysis” (fancy term for comparing search results for both forms) is your best friend here. If the results overlap a lot, you can target either. If not, pick the one that matches your content’s intent.

Real-World Example: E-Commerce

Let’s say you sell shoes (because who doesn’t love a good shoe example?). If you optimize for “shoe,” you might attract people wanting to know what a shoe is (not your target buyer, unless you’re selling to aliens). But “shoes”? Now you’re talking to shoppers ready to browse, compare, and buy.

• Product detail pages: Go singular (“running shoe”).
• Category/listing pages: Go plural (“running shoes”).

This isn’t just theory — case studies show that plural keywords for e-commerce category pages often yield more diverse and refined results, reflecting users who are further along in the buying journey.

Pro Tips for SMBs and Agencies

We get it — running a business or agency means juggling a million things (and occasionally, dropping a few). Here’s how to make the singular vs plural keywords SEO decision without losing your sanity:

• Do your research. Check search volumes for both forms.
• Match intent. Plural for categories, singular for info pages.
• Analyze SERPs. If Google treats them differently, so should you.
• Monitor performance. Adjust based on what drives qualified traffic and conversions.
• Watch for weird words. Some words change meaning between singular and plural (hello, “glasses”), so double-check before optimizing.

What the Experts Say

“The form you choose can shape who finds your content and what they expect to see.”

SEO pros agree: it’s all about user intent and content type. For e-commerce, prioritize plural for categories and singular for detailed info. For blogs and agencies, a mix (with a dash of SERP analysis) is your secret sauce.
