If you are searching for a "SEM agency Seattle" to handle your search marketing, you are most likely trying to solve a visibility problem on Google and Bing — and you have probably been handed conflicting advice about whether you need paid search, SEO, or both. The term SEM, search engine marketing, covers the entire field: paid ads on Google and Bing plus the organic SEO work that earns unpaid rankings. A real SEM agency runs both halves together, because paid and organic search share keyword research, landing pages, and conversion data. Splitting them across two vendors is how most Seattle businesses end up with ads that point to pages that do not convert and SEO that ignores the keywords actually driving paid leads.
This guide explains what a Seattle SEM agency should cover, how local pricing works, and how to choose a partner that manages paid and organic search as one system rather than two disconnected services. For the paid half specifically, our PPC management services in Seattle guide breaks down Google Ads management; for the organic half, our Seattle web design agency guide covers the conversion-side foundation.
What a Seattle SEM agency should actually cover
A complete SEM engagement should include both the paid and organic sides of search visibility, managed against shared goals:
- Paid search (PPC): Google Ads Search campaigns, Performance Max, Bing Ads, remarketing, and shopping feeds where relevant. This includes keyword targeting, match-type strategy, bid management, ad copy testing, and negative keyword pruning to keep spend efficient.
- SEO (organic search): technical site health, on-page optimization, content targeting commercial and local-intent keywords, internal linking, and Google Business Profile optimization for the Seattle metro. SEO is what makes paid traffic land on pages that actually convert.
- Keyword research shared across both: the same commercial and local-intent keyword set should feed both paid campaigns and organic content, so you are not paying an ad agency and an SEO shop to research the same terms twice.
- Landing page optimization: the pages ads send traffic to need to load fast, match the ad's promise, and convert. A SEM agency that cannot touch landing pages is only running half the system.
- Conversion tracking and attribution: Google Ads conversion tracking, GA4 events, and a clear attribution model so you know which campaigns and keywords produce leads, not just clicks.
- Reporting tied to revenue, not vanity metrics: monthly reporting should show cost per lead, cost per acquisition, and revenue per campaign — not just impressions, clicks, and click-through rate.
If a vendor lists paid search but not SEO, or SEO but not paid, you are looking at half a SEM program. The advantage of one agency running both is that paid and organic stop competing for budget and start reinforcing each other.
How Seattle SEM agency pricing works
Seattle SEM pricing usually falls into one of three models, and a transparent agency will quote management and media spend separately:
- Flat monthly management fee: $1,000 to $3,500 per month for small and mid-market accounts. Predictable, but make sure the fee scales with account complexity rather than resetting every month.
- Percentage of ad spend: typically 10% to 20% of monthly ad spend, often with a minimum. This aligns the agency's incentive with spend growth, which can push budgets up — confirm there is a ceiling or a spend-based review.
- Hybrid: a lower base fee ($500 to $1,500) plus a smaller spend percentage (5% to 10%). Common for accounts that need both strategy work and hands-on management.
Setup, audit, or onboarding fees run $500 to $2,000 one-time and cover account restructuring, conversion tracking setup, and keyword research. Ad spend itself is budgeted directly with Google and Bing — the agency should never collect media spend through its own invoice, because that hides the real cost per click.
When comparing Seattle SEM agencies, ask for a quote that separates management fee, media spend, and any one-time setup. A quote that bundles everything into a single number makes it impossible to tell whether you are paying for service or for ads.
Why paid and organic search belong under one agency
The case for running paid and organic search with the same agency is not convenience — it is data. Paid search is the fastest keyword research tool that exists: within a week of launch, Google Ads tells you exactly which search terms convert for your Seattle business. That data should flow directly into the SEO content plan, so the organic program targets keywords with proven conversion rather than guessed search volume. The reverse is also true: organic search queries from Google Search Console reveal long-tail intent that paid campaigns should test as new keywords.
When paid and organic live in separate shops, that feedback loop breaks. The ad agency optimizes for click cost without knowing which terms convert organically, and the SEO shop builds content without knowing which terms already produce paid leads. The result is duplicated work, conflicting keyword lists, and budgets that fight each other instead of compounding.
How to choose a Seattle SEM agency
When you compare Seattle SEM agencies, ask these questions before signing:
- Do you manage both paid search and SEO in-house, or do you partner out one half? A vendor that subs out SEO is a PPC shop, not a SEM agency. Ask who specifically does the SEO work.
- How do you share keyword data between paid and organic? The right answer is a shared keyword set with paid conversion data feeding the content plan. "We keep them separate" is the wrong answer.
- Can you show a Seattle-area case study with cost per lead and revenue, not just clicks? A real SEM agency reports on leads and revenue. If the case study shows only impressions and CTR, the agency is measuring activity, not outcomes.
- Who owns the Google Ads and GA4 accounts? You should own them, with the agency as a manager. An agency that insists on owning the accounts is holding your data hostage.
- What is your approach to landing pages? If the agency cannot build or edit landing pages, it cannot fix the conversion side of paid search — only the traffic side.
