How to Do Keyword Research for a Shopify Blog

Most Shopify blogs fail for one boring reason: they write about topics no one searches for. Keyword research fixes that. It tells you the exact phrases real shoppers type before they buy — so every post you publish has a shot at bringing in traffic that already wants what you sell.

Key takeaways

• Start from your own products and collections — the best keywords are the problems your catalog already solves.
• Prioritise intent over volume: a 90-searches-a-month phrase with buying intent beats a 10,000-volume phrase that never converts.
• Group keywords into topics, then write one post per topic — not one thin post per keyword.
• Check what already ranks before you write; if the top results are giant brands, pick a more specific long-tail angle.
• Map every keyword to a real product or collection so the post can link out and actually sell.

Start with your catalog, not a tool

Open your products and collections and write down the questions a shopper would ask before buying each one. A candle store selling soy candles already owns topics like "how long do soy candles burn", "soy vs paraffin candles", and "best candles for small rooms". These aren't guesses — they're the real decisions standing between a browser and a purchase.

This is also why catalog-grounded writing wins: a post built from a product you actually sell can answer the question and point the reader at the thing that solves it.

Judge intent before volume

Search volume is a vanity metric on its own. A phrase like "perfume" gets enormous traffic, but the person typing it could be doing anything — a school project, price comparison, or nothing at all. "How to make perfume last all day" is far smaller, but the reader has a problem you can solve and a product that solves it.

Sort every candidate keyword into rough intent buckets — informational ("how to…"), commercial ("best… for…"), and transactional ("buy…"). For a blog, the sweet spot is informational and commercial phrases that sit one step before a purchase.

Win with long-tail phrases

New and mid-sized stores rarely outrank national brands for two-word head terms. You don't need to. Longer, more specific phrases ("layering white musk with vanilla", "gifts for a coffee lover under $30") have less competition, clearer intent, and convert better because the post matches exactly what the reader wanted.

A quick test: search the phrase yourself. If page one is wall-to-wall huge retailers, niche down until you see blogs, forums, and smaller shops — that's a gap you can fill.

Cluster keywords into topics

Don't write a separate 300-word post for every keyword variation — that creates thin pages that compete with each other. Group related phrases into a single topic and write one strong post that covers them all. "How long do soy candles last", "why does my candle tunnel", and "how to make candles burn evenly" belong in one thorough guide, not three flimsy ones.

Map each topic to a product

Before you write, decide which product or collection the post should send readers to. A post with no destination is a dead end; a post that naturally links to the right product is a salesperson. Keep the article genuinely helpful first — earn the click by answering the question well — then link where it makes sense.

If keyword research, topic clustering, and product mapping sound like a lot to do by hand for every post, that's exactly the busywork SEO Bison automates — it reads your catalog, finds the gaps, and drafts posts already tied to the right products.

FAQ

How many keywords should one blog post target?

One primary phrase plus a handful of closely related variations. Trying to rank a single post for many unrelated keywords dilutes it. Cover one topic thoroughly and the related phrases come along for free.

Do I need a paid keyword tool to start?

No. Google's autocomplete, the "People also ask" and "Related searches" boxes, and your own product FAQs are enough to build a strong first list. Paid tools help you scale and check volume, but they're not a prerequisite.

How do I know if a keyword is too competitive?

Search it. If page one is dominated by major brands and marketplaces, it's too competitive for now — choose a longer, more specific version where smaller sites still rank.

The short version

Great Shopify blog keywords come from your own catalog, favour intent over raw volume, lean long-tail, cluster into topics, and always point back to a product. Do that and every post you publish is working toward a sale — not just a word count.
