Amazon Affiliate Keywords: 8 Patterns That Convert and the Ones That Don't
Affiliate keyword research is usually taught as a tool workflow: type a seed, export a thousand rows, sort by volume. The step that matters is the one the export can't do, which is recognising which of those rows are searches by someone about to buy.
Buying searches follow a small number of patterns, and once you know them you can spot them in a list, or build them without a list at all.
This post sets out the eight patterns Amazon affiliate sites earn from, roughly how each one converts and why, then the patterns that rank nicely and pay almost nothing. The informational vs commercial post covers the intent split at a higher level; this one is the field guide.
The short answer
The patterns that pay all have a product noun plus a signal that the searcher is choosing: a situation ("for small apartments"), a comparison ("vs"), a budget ("under $100"), a doubt ("worth it"), a brand with "review", "alternatives", a feature, or a user.
The patterns that don't pay are bare product names, "how to" questions, "what is", and anything about a problem rather than a purchase. Write the paying patterns first, the others to support them.
The eight patterns that convert
| Pattern | Example | Why it converts | Page to write |
|---|---|---|---|
| Best [product] for [situation] | best air purifier for a bedroom | Decided to buy, needs it narrowed | Buyer guide |
| [A] vs [B] | Kindle Paperwhite vs Kobo Clara | Down to two; one more fact decides | Comparison |
| [product] under $[amount] | best projector under $300 | Budget set, wants the pick | Buyer guide (budget) |
| Is [product] worth it | is a standing desk worth it | Wants permission to buy | Single review or short guide |
| [brand/model] review | Instant Pot Duo review | One product, final check | Single review |
| [product] alternatives | Dyson V15 alternatives | Wants the same thing cheaper | Short guide, 4 to 6 picks |
| [product] with [feature] | treadmill with incline and folding | Knows the spec that matters | Buyer guide |
| [product] for [user] | tablet for seniors | Buying for someone; wants reassurance | Buyer guide |
1. Best [product] for [situation]
The backbone of every affiliate site. "Best air purifier" is owned by national publications; "best air purifier for a bedroom" often isn't, and the searcher has a bedroom and a budget and wants to be told. A ten-product guide with a clear top pick converts at the high end of anything you'll write.
2. [A] vs [B]
The closest a search gets to the checkout. The searcher has two tabs open and needs the one difference that decides it. The page is short, the comparison table is the whole point, and both links earn. These keywords are small, and a site in a niche can have fifty of them.
3. [product] under $[amount]
A budget in the query means the decision is half made. The guide should respect the number (nothing over it, however good) and lead with the pick that's clearly best inside it. Keep the amount out of the title if your site runs outside the US, and never print prices in the text; they go stale, and Amazon's rules on displaying them are strict.
4. Is [product] worth it
The searcher wants to be talked into it, or talked out of it by someone honest. A page that says "yes, if you..." and "no, if you..." with the product linked earns well, because the people who get the "yes" buy. Don't dodge; a page that won't answer the question loses to one that does.
5. [brand/model] review
A single product, final check before buying. Conversion is high and the volume is tied to the product's popularity. The review titles post covers how to title these; the body needs the specific facts the listing hides and a plain verdict.
6. [product] alternatives
Someone priced the famous one and flinched. They want the same job done for less, and they're ready. Four to six picks, each with "what you give up vs the original", and a link to the original too, because some of them go back and buy it.
7. [product] with [feature]
The searcher knows the spec that matters to them. Filter the products by it, say so in the first line, and don't pad with products that don't have the feature. These are the keywords the big sites skip because they're too narrow to be worth a staff writer.
8. [product] for [user]
Gifts, parents buying for children, children buying for parents. The buyer isn't the user, so the guide needs to explain what the user will find easy or hard, and the "for seniors" or "for a 10-year-old" framing has to be taken seriously rather than used as a tag on a generic list.
The patterns that rank but don't pay
- Bare product names. "Kindle Paperwhite". Amazon, the manufacturer and the retailers own the results, and the searcher may only want the product page.
- How to [use/fix/clean] [product]. The searcher owns it already. Useful for topical coverage and for links into the guides; close to zero commission on its own.
- What is [product] / how does [product] work. Curiosity, not purchase. Good for a site's authority; bad for earnings.
- [product] problems / not working / won't turn on. Frustration traffic. It occasionally converts to a replacement, mostly it doesn't.
- Head terms. "Running shoes", "air fryer". Huge volume, undefined intent, results owned by brands and retailers. Write the hub page for structure, not for the ranking.
None of these are useless. A site that only has buying pages looks thin to Google and has nowhere to link from. The order matters: paying patterns first, supporting pages after, as the intent post linked above lays out.
Building the list without a tool
Write down the product nouns in your niche (fifteen to forty). Run each through the eight patterns. That's a grid of a few hundred candidates.
Then check each against Google's autocomplete and the related searches at the bottom of the results, and keep the ones that appear; those are phrases real people type. Finally judge the competition from the results page, the way the low-competition post describes.
Two patterns stacked ("best treadmill under $500 for a small apartment") produce the most specific, least contested, highest-converting keywords on the list. Volume tools will show a dash for them. Write them anyway.
Doing it with AffSERP
AffSERP's Keyword Explorer runs a seed term through autocomplete with these pattern expansions built in, so the grid above comes out as a list, and Keyword Grouping sorts the results by intent, separating the eight paying patterns from the supporting ones.
Each buying keyword has a Write button that sends it to the X Best Review tool for a guide, and the supporting ones go to the Informational Article tool. The judgement about which pattern a keyword fits is the part worth learning by hand first, because it's the same judgement you'll use when reading the tool's output.
FAQ
What are the best keywords for Amazon affiliate sites?
Keywords where the searcher has decided to buy something and is choosing which one: 'best [product] for [situation]', '[product A] vs [product B]', '[product] under $[amount]', '[brand] [product] review' and 'is [product] worth it'. They have small volumes and high conversion. Head terms like 'running shoes' have the volume and almost none of the buyers.
Do 'how to' keywords make money for affiliate sites?
Rarely on their own. A 'how to' searcher wants to do something, not buy something, and most of them already own the product. They're worth writing to build topical coverage and to link into the buying guides, which is where the commission happens. Expect them to rank more easily and convert much less.
Should I target product-name keywords like 'Kindle Paperwhite'?
Not the bare name. Amazon itself, the manufacturer and the big retailers own those results, and the searcher may just want the product page. The versions with intent attached ('Kindle Paperwhite vs Kindle', 'Paperwhite worth it', 'Paperwhite review') are the ones a review site can win and earn from.
How do I find keyword patterns for my niche?
Take each product noun in the niche and run it through the patterns: best ___ for, ___ vs, ___ under, ___ review, is ___ worth it, ___ alternatives, ___ with [feature], ___ for [user]. Check which versions appear in Google's autocomplete and related searches; those are the ones people actually type.
