How to Find a Good SEO Agency: 7 Steps (and the Red Flags to Avoid)

The Direct Answer: How to Find a Good SEO Agency in 7 Steps

If you want to know how to find a good SEO agency in 7 steps (and the red flags to avoid), here is the shortest version: shortlist by proof, not promises. Ask every candidate for two to three client sites they actually ranked. Check reviews on independent directories rather than relying on cherry-picked testimonials. And reject anyone guaranteeing #1 rankings, because no legitimate SEO professional can make that promise.

The best predictor of SEO success is verified, recent evidence that an agency has moved the needle for businesses similar to yours.

That sounds simple, but the SEO services market is crowded and noisy. With over 47,000 verified marketing agencies in Pick an Agency's directory alone, separating the competent from the incompetent takes a structured approach. The seven steps below give you that structure. Follow them in order, and you will dramatically reduce the odds of hiring an agency that wastes your budget or, worse, damages your site's reputation with Google.

Step 1: Define Your SEO Goals Before You Search

Most failed agency relationships start with vague expectations. Before you shortlist anyone, write down exactly what success looks like for your business. Are you trying to rank for specific high-intent keywords? Recover from a traffic drop? Build topical authority in a new vertical? Fix technical issues that are holding you back?

Agencies specialize, and the right fit depends on whether you need technical SEO, content-led SEO, local SEO, or link acquisition.

According to Pick an Agency's 2026 data, 85% of agencies offer three or fewer services. That means the agency that excels at technical audits may have no meaningful content production capability, and vice versa. Define your goals first so you can filter for agencies whose specialization matches your actual need.

Step 2: Ask for Verifiable Ranking Examples

Any agency can claim expertise. Few can show you live proof. When you ask for case studies, push past the polished PDF and request specific URLs of client sites they have ranked.

A credible agency will share two to three client sites where you can verify rankings yourself using any third-party SEO tool.

Here is what to ask for:

• The domain name and target keywords they optimized
• The timeframe of the engagement
• Permission to independently verify current rankings and estimated traffic
• Context on the competitive landscape and starting point

If an agency refuses to share any verifiable examples, citing confidentiality for every client, that is a yellow flag. Most agencies have at least a few clients who are happy to be referenced, or they have their own properties they have ranked. No verifiable proof usually means no real results.

This step alone will eliminate a significant portion of underqualified agencies from your list. For more questions to ask during vetting, see our guide on questions to ask a marketing agency.

Step 3: Check Reviews on Independent Directories

Testimonials on an agency's website are curated. You need to see what clients say in spaces the agency cannot control. Independent review directories aggregate feedback from real engagements and give you a more balanced picture.

Cross-reference reviews on at least two independent platforms before shortlisting any SEO agency.

However, be aware that reviews are not infallible. Pick an Agency's analysis of 4.2 million aggregated reviews found that over 60% of agencies hold a perfect 5.0 rating. That level of uniformity suggests rating inflation is real, and a perfect score alone is not a meaningful differentiator.

Look beyond the star count. Read the actual review text. Check how the agency responds to negative feedback. And consider whether the reviews mention specific outcomes or just generic praise. For a deeper analysis of this problem, read can you trust marketing agency ratings.

Step 4: Evaluate Their SEO Process and Deliverables

Ask every candidate to walk you through their standard engagement. What do the first 30 days look like? What deliverables will you receive monthly? How do they prioritize tasks?

A good SEO agency should articulate a clear, logical process that includes auditing, prioritization, execution, and measurement.

Expect to hear about:

1. A technical audit to identify site health issues
2. Keyword and competitive research tailored to your market
3. On-page optimization recommendations or execution
4. Content strategy or production, if relevant to your goals
5. Link acquisition approach, with an explanation of their methods
6. Monthly reporting with clear metrics tied to your goals

If an agency cannot explain their process in plain language, or if they rely heavily on jargon without concrete details, they may be masking a lack of substance. SEO is not magic. It is a set of practices that can be described clearly.

Google's own SEO Starter Guide outlines the fundamentals. Any agency you hire should be operating in alignment with these documented best practices, not working around them.

Step 5: Assess Team Size and Structure

Understand who will actually work on your account. Will it be senior strategists, junior staff, or contractors? How many clients does each team member handle?

Knowing the team structure helps you gauge how much attention your account will actually receive.

According to Pick an Agency's 2026 data, 62% of agencies have fewer than five people. That is not inherently bad. Small teams can be highly effective. But it does mean you should ask direct questions about capacity. If a three-person shop is managing 30 clients, your project is not getting deep focus.

Ask to meet the people who will do the work, not just the salespeople. If the agency is evasive about introductions, consider it a warning sign.

Step 6: Clarify Reporting and Communication Expectations

Before signing anything, agree on how success will be measured and how often you will communicate. Monthly reports should be standard, but the content of those reports matters more than their frequency.

Insist on reports that tie activity to outcomes, showing what was done, what changed, and what happens next.

Good SEO reporting includes:

• Ranking changes for target keywords
• Organic traffic trends, segmented by landing page or topic
• Technical issues identified and resolved
• Links acquired, with source and quality context
• Content published or optimized
• Next month's priorities and rationale

Avoid agencies that send automated dashboards with no interpretation. Data without context is not useful. You need an agency that can explain what the numbers mean and what they plan to do about them.

You can browse agencies that specialize in organic search through the SEO agencies directory or learn more about the service category at /services/seo.

Step 7: Start with a Defined Pilot Project

Even after thorough vetting, you cannot fully evaluate an agency until you work with them. Reduce your risk by starting with a scoped pilot rather than a long-term retainer.

A pilot project of 60 to 90 days lets you assess work quality, communication, and responsiveness before committing to a longer engagement.

Good pilot projects include:

• A comprehensive technical audit with prioritized recommendations
• A content refresh project targeting a specific set of pages
• A keyword and competitive analysis for a new market or product

Set clear success criteria at the start. What will you evaluate? Deliverable quality? Communication frequency? Strategic insight? At the end of the pilot, you will have real evidence of how the agency operates, not just promises.

Red Flags That Should Disqualify an SEO Agency

Knowing what to avoid is as important as knowing what to look for. These red flags should immediately move an agency off your shortlist:

If an agency guarantees specific rankings, uses secretive tactics, or cannot explain their methods, walk away.

• Guaranteeing #1 rankings: No one controls Google's algorithm. Anyone promising specific positions is either lying or planning to use risky tactics that could get your site penalized.
• Refusing to explain their link building methods: If an agency will not tell you how they acquire links, they are likely using tactics that violate Google's guidelines.
• Owning your content or access: You should always retain ownership of website content, analytics access, and Search Console data. Agencies that insist on controlling these assets are creating lock-in, not value.
• No clear contract or scope: Vague agreements lead to disputes. Reject any agency that will not clearly define deliverables, timelines, and exit terms in writing.
• Pressure to sign immediately: High-pressure sales tactics are a signal that an agency depends on closing deals rather than delivering results.
• Extremely low pricing: SEO requires skilled labor. Prices far below market rates usually mean offshore execution, inexperienced staff, or automated work that adds no real value.

Why This Process Works

These seven steps work because they shift the evaluation from what agencies say to what they can prove. Understanding how to find a good SEO agency in 7 steps (and the red flags to avoid) gives you a repeatable framework for every hire.

The SEO industry has low barriers to entry. Half of agencies were founded after 2015, with the biggest surge between 2020 and 2024. Many entered the market during a period of rapid digital growth, and not all have developed the skills or track records to justify their fees.

By demanding proof, checking independent reviews, understanding their process, and starting with a pilot, you protect yourself from the large percentage of agencies that overpromise and underdeliver.

FAQ

How do I find a good SEO agency?

Start by defining your specific SEO goals, then shortlist agencies based on verifiable results rather than claims. Ask for two to three client sites they have ranked, check reviews on independent directories, evaluate their process and team structure, and begin with a pilot project before committing to a longer engagement. Reject any agency that guarantees specific rankings or refuses to explain their methods.

How much does an SEO agency cost?

SEO agency pricing varies widely based on scope, competition, and agency expertise. Monthly retainers typically range from a few hundred dollars for basic local SEO to several thousand for competitive national or international campaigns. Be wary of prices far below market rates, as they often indicate low-quality work. Always tie pricing to specific deliverables and expected outcomes rather than vague promises.

What are SEO agency red flags?

The biggest red flags include guaranteeing specific rankings, refusing to explain link building methods, requiring ownership of your content or analytics access, using high-pressure sales tactics, and offering pricing that seems too good to be true. Any agency that cannot provide verifiable examples of past results or that relies on secrecy rather than transparency should be avoided.

How long does it take to see results from SEO?

Most SEO campaigns take three to six months to show measurable results, though this varies based on your site's starting point, competition level, and the scope of work required. Be skeptical of agencies promising fast results, as sustainable SEO improvements require time to build authority and trust with search engines. A good agency will set realistic expectations upfront and provide incremental progress updates along the way.
