Best SEO Company Perth

Can you trust lists of the best SEO in Perth?

Mostly no. Of three high-ranking “best SEO agencies in Perth” lists we checked in October 2026, two were published by a Perth agency that placed itself at number one. The third, from a publisher running similar lists for other cities, left itself out but didn’t say how it ordered the agencies. A ranking written by a contestant is a sales page, not a review.

That doesn’t make every agency on those lists bad. It means the order tells you who wrote the list, not who suits your business. Before you rely on any list, check three things:

1. Who published it? Look at the domain. If it’s an agency, assume it’s marketing.
2. Is the publisher in it? Self-inclusion near the top is the clearest sign of a promotional list.
3. Is the method about you? Most lists judge on Google review averages and office locations. Neither tells you whether an agency can win leads for a plumber in Baldivis or a clinic in Subiaco.

The rest of this guide gives you a scoring method you can run yourself. For a quick pass-or-fail check on any SEO company, see our SEO company Perth scorecard. This page goes further: it weights the criteria by business type and shows how to test what an agency tells you.

Why does the best SEO company in Perth depend on your business?

Because different businesses win customers from different parts of Google. A trade wins from the Maps pack, an online store from product and category pages, and a law firm from deep service pages in one of the most competitive markets online. An agency that excels at one can be average at another.

Business type	Where customers find you	What the agency must be good at	Proof to ask for	Typical Perth retainer
Trade or home service	Maps pack and “service + suburb” searches	Google Business Profile, reviews, suburb pages	A trade client ranking in Maps you can check	$800–$1,500 a month (more if competitive)
Clinic or allied health	Maps, “near me” and treatment searches	Compliant content, multi-practitioner pages, bookings tracking	A clinic site ranking for a treatment plus suburb	$3,000–$6,000+ a month
Ecommerce	Product, category and comparison searches	Site structure, technical SEO, product data	Revenue from organic search, not just traffic	$3,000–$6,000+ a month
Law firm	Practice-area and urgent-need searches	Authority links, in-depth practice pages, intake tracking	A firm ranking for a practice area, not its own name	$3,000–$6,000+ a month

Clinics carry an extra test. Ahpra’s advertising guidelines restrict testimonials about clinical care, so an agency that suggests putting patient reviews on treatment pages has just told you it doesn’t know the rules. Our guides for tradies, ecommerce and law firms cover each type in more depth.

How do you score the best SEO agency in Perth out of 100?

Rate each agency 0–5 on seven criteria using evidence, multiply each rating by the weight for your business type, divide by 5 and add them up. The total is out of 100. Use the column that matches your business, because the weights change what “best” means.

Criterion	Trade	Clinic	Ecommerce	Law
Verified results in businesses like yours	20	15	15	20
Strategy fit for how your customers search	20	20	10	10
Reporting tied to enquiries or revenue	20	15	20	15
Technical capability	5	5	25	10
Content and page-building quality	10	20	10	20
Link building transparency	10	10	10	15
Terms, ownership and who does the work	15	15	10	10
Total	100	100	100	100

Four answers knock an agency out regardless of score: a guaranteed ranking, a 12-month lock-in with exit fees, a “links per month” package it won’t itemise, or a sample report with no enquiry data.

Worked example (hypothetical figures). An electrician in Wanneroo compares Agency A, a large firm whose case studies are online stores, with Agency B, a smaller firm with checkable trade clients.

Criterion (trade weight)	Agency A rating	A points	Agency B rating	B points
Verified results (20)	2	8	4	16
Strategy fit (20)	3	12	5	20
Enquiry reporting (20)	2	8	4	16
Technical (5)	5	5	3	3
Content (10)	4	8	3	6
Links (10)	2	4	4	8
Terms and team (15)	3	9	5	15
Score		54		84

Run the same two agencies for an online store and the result flips. “Businesses like yours” now means online stores, so Agency A’s ratings for verified results and strategy fit rise while Agency B’s fall, and Agency A’s technical depth carries the heavier ecommerce weight. Agency A wins 72 to 62. Neither agency is “the best”. Each is best for someone.

What should you ask on the first call, and what do good answers sound like?

Ask every agency the same eight questions and write the answers down. Good answers are specific, name real searches and sites, and admit limits. Bad answers are vague, lean on jargon or push you to sign before you’ve seen anything in writing.

Question	A good answer sounds like	A bad answer sounds like
Which five searches would you target, and how many people make them?	“Electrician Wanneroo, switchboard upgrade Joondalup… here are the monthly volumes, and two are thin.”	“We’ll get you ranking for ‘electrician Perth’.”
Which client site like mine can I check today?	Names the site and the search, and invites you to look now	A logo wall, or “all our clients are under NDA”
What will my monthly report show?	Calls and forms from organic search, plus the work done	Rankings and a “visibility score” only
What links would you build, and can I see the list?	Local sponsorships, suppliers, industry bodies; a live list every month	“Our package includes 20 high-DA links a month”
Who actually does the work?	A named person, with any outsourcing disclosed	“Our team handles it”
What happens if I leave after three months?	30 days’ notice, and you keep the pages, profile and accounts	Exit fees, or they keep the content
What wouldn’t you do for my business?	Names work that isn’t worth paying for in your case	Everything is in the package
When should I expect results?	Early movement in 6–12 weeks, more leads in 3–6 months, competitive terms 6–12 months	“Page one in 30 days”

The “what wouldn’t you do” question is the most revealing. An agency that can tell you what not to buy is thinking about your return. One that can’t is thinking about its retainer.

How do you check an agency’s own rankings and claimed results?

Check them yourself in about 20 minutes, before the first call. Search the terms the agency claims, confirm the results are organic and current, and test its case studies on live sites. An agency’s own word, screenshots and awards are claims. A search result you can see today is evidence.

1. Search its claims in a private window. Use a private window on your phone in Perth. Note whether the agency appears as an ad (marked “Sponsored”), in the Maps pack or in the organic results. Paying to appear proves budget, not skill.
2. Test its case studies. For each one, search the keyword it claims for that client. If the client no longer ranks, or the site has changed hands, ask why.
3. Check relevance, not just rank. An agency ranking for “SEO Perth” proves it can rank an agency website. It doesn’t prove it can rank a physio in Joondalup. Weight trade proof for a trade, clinic proof for a clinic.
4. Look up the business. The government’s ABN Lookup shows the legal entity and how long its ABN has been active, which is worth comparing with any “since” claims.
5. Read its review pattern. A steady spread over years is normal. Dozens of five-star reviews in one month is not.
6. Ask for Search Console on a screen share. Clicks and impressions over 12 months from Google’s own tool are much harder to cherry-pick than a ranking screenshot.

If an agency won’t let you verify anything before you pay, score its “verified results” criterion zero.

How do you compare top SEO companies in Perth side by side?

Print the sheet below, fill in your weights from the scorecard, and complete one column per agency during or straight after each call. Comparing three agencies on one page stops the most confident pitch from winning by default.

Criterion	Your weight	Agency 1 (0–5)	Agency 2 (0–5)	Agency 3 (0–5)
Verified results in businesses like yours
Strategy fit for how your customers search
Reporting tied to enquiries or revenue
Technical capability
Content and page-building quality
Link building transparency
Terms, ownership and who does the work
Knock-out triggered? (yes/no)
Monthly price quoted
Score out of 100

Price goes on the sheet but not in the score. Compare it against typical SEO pricing in Perth to check the quote is realistic, then divide it by the hours included.

We’d ask you to score us on the same sheet. We work month-to-month with no lock-in, report on enquiries in plain English and quote only after a free SEO audit, so you can compare our plan against anyone else’s with your own site’s data in front of you.
