How to shortlist one of them

Use the score to cut the list, then use the profile to make the call. Three checks that catch most bad fits:

  1. Read the local visibility number. An agency selling you rankings that does not rank for its own category in Seattle owes you an explanation. Sometimes there is a good one, such as a business built entirely on referrals.
  2. Ask about the weaknesses we list. Every profile names what is holding that site back. Asking why their own site has no structured data tells you more in one minute than any pitch deck.
  3. Match the client size, not the logo wall. The client-size split on each profile shows who they actually serve. A shop that lives on enterprise retainers will not give a local clinic much attention.

What SEO costs in Seattle

The most common minimum engagement in this market is $5,000+. Where an agency states its rates publicly we mark the figure Published; where it does not, the band is our estimate for a firm of that size in this city and is labelled Estimated. Either way it is a starting point for the conversation, not a quote, and any agency worth hiring will scope before pricing.

Questions

SEO agencies in Seattle: common questions

Who is the best SEO agency in Seattle?

What is local SEO Seattle?

How to choose an SEO company in Seattle?

Select an SEO company in Seattle by reviewing their scores, typical project minimums, and client ratings. Consider their expertise in local SEO and ask about their success metrics.

What SEO services are offered in Seattle?

Seattle agencies offer a range of SEO services including technical audits, on-page optimization, content creation, and local SEO strategies tailored to your business.

How are these Seattle SEO agencies ranked?

By the SEO quality of their own websites, measured automatically and identically for all 17 of them. The score blends technical setup (30%), on-page basics (28%), content depth (22%) and whether the agency actually ranks for local searches in Seattle (20%). Nobody pays for placement and nobody submits their own numbers.

Is a high score proof an agency is good at SEO?

It is evidence, not proof. An agency that cannot get structured data, meta descriptions or headings right on its own site is showing you how it works. But a great score with no case studies means little, so read the reviews, the case studies and the local visibility number together before you shortlist anyone.

What does an SEO agency in Seattle cost?

The most common minimum engagement across these 17 agencies is $5,000+, with hourly rates typically falling between $100 and $200. Figures we could confirm on a public page are marked Published; the rest are labelled Estimated, so treat them as a starting range rather than a quote.

Why do some agencies score badly on local visibility?

Local visibility counts how often an agency appears in the search results their own prospects would use in Seattle, such as "seo agency Seattle". Of the 17 rated here, 4 show up in at least three of those eight searches. A low number usually means the agency wins work by referral or ads rather than by ranking.

How often do the scores change?

Sites are re-measured as the crawler comes back around to each city, so a redesign or a technical fix shows up in the score. Agencies that claim their profile can also submit corrections, which our team reviews before anything goes live.

Can my agency get listed or correct its profile?

Listing is automatic: the crawler finds agencies from public search results, so there is nothing to buy. To manage a listing, open your profile and claim it with an email on your own domain. That unlocks a dashboard with profile analytics, quote requests, editable details and an updates feed.
