How to Brief an SEO Agency for Technical Audits, On-Page Optimization & Performance

You’ve decided to hire an SEO agency. Good move. But here’s the thing: the quality of what you get back is almost entirely determined by the quality of what you send in. A vague brief like “we need more traffic” will return a vague proposal with generic tactics. A precise brief, on the other hand, forces the agency to show their work—and exposes any agency that relies on black-hat links or guarantees they can’t keep. This checklist walks you through exactly what to include when briefing an SEO agency for technical audits, on-page optimization, and performance improvements. No fluff, no invented metrics—just the operational details that separate a real partner from a reseller.

1. Start with Your Current Technical Baseline

Before any optimization work begins, the agency needs to understand what they’re walking into. Your brief should include a snapshot of your current technical SEO health. This isn’t about showing off—it’s about setting a benchmark. Include:

• Current crawl budget status. Have you checked your crawl stats in Google Search Console? If not, note that. Agencies need to know if Googlebot is wasting time on thin pages or getting stuck in redirect chains.
• Core Web Vitals data. Pull your LCP, CLS, and INP scores from the CrUX report or PageSpeed Insights. If you don’t have this, say so. A good agency will audit this anyway, but flagging it early tells them you’re serious about performance.
• Existing XML sitemap and robots.txt files. Share the URLs. If you’ve never updated your robots.txt, that’s useful information too. Many sites accidentally block important resources here.
• Canonical tag usage. Do you have self-referencing canonicals? Are there stray tags pointing to the wrong pages? Mention any known issues.

A table here helps the agency quickly assess priorities:

Risk alert: If an agency tells you they can “fix Core Web Vitals overnight” without seeing your current scores, walk away. Real performance improvements require diagnosing the root cause—often a combination of server config, image optimization, and third-party scripts. No reputable agency guarantees a specific score without an audit first.

2. Define the Scope of On-Page Optimization

On-page optimization covers everything from meta tags to content structure. But not all on-page work is created equal. Your brief should specify whether you need:

• Keyword research and intent mapping. This is the foundation. Don’t just ask for “keywords.” Ask for a breakdown of search intent—informational, navigational, transactional—and how the agency plans to map those to your existing pages. A good agency will show you the gap between what you rank for and what you should rank for.
• Content strategy. Are you looking for new content, or optimization of existing pages? Be clear. Many agencies will happily sell you 50 blog posts, but if your product pages are thin, that’s where the real opportunity lies.
• Duplicate content resolution. If you have product descriptions copied from manufacturers or syndicated content, flag it. The agency needs to know whether they’re dealing with canonicalization issues or a full rewrite.

A common mistake is treating on-page optimization as a one-time task. It’s not. Search intent shifts, competitors update their pages, and Google’s algorithm evolves. Your brief should ask for a recurring review cycle—quarterly, at minimum.

3. Specify Your Link Building Philosophy

Link building is where most briefs go wrong. Either they’re too vague (“we need more backlinks”) or they include dangerous instructions (“buy links from high-DA sites”). Your brief should communicate your risk tolerance and your expectations for link quality.

What to include:

• Your current backlink profile. Share a link to a Majestic, Ahrefs, or SEMrush report. The agency needs to see your Trust Flow and Domain Authority baselines. If you’ve had a manual action in the past, disclose it.
• Your target audience and industry. Links from relevant sites matter more than links from high-DA sites in unrelated niches. A link from a respected industry blog is worth more than a link from a generic directory.
• Your stance on black-hat tactics. State it explicitly: “We do not accept paid links, PBNs, or automated outreach.” This protects you from agencies that cut corners. If an agency pushes back, that’s a red flag.

What not to include: Don’t ask for a specific number of links per month. Quality link acquisition is unpredictable. A good agency will set a target range based on your industry competitiveness, not a fixed number. And never ask for “guaranteed first page ranking”—that’s a promise no ethical agency can make.

4. Request a Performance & Reporting Framework

The brief should outline how success will be measured. This isn’t just about traffic—it’s about the metrics that actually impact your business. Ask the agency to propose:

• Primary KPIs: Organic sessions, keyword rankings (by intent), conversion rate from organic traffic, and Core Web Vitals pass rate.
• Secondary KPIs: Crawl budget utilization, index coverage, backlink acquisition rate, and content engagement metrics.
• Reporting cadence: Monthly reports are standard, but ask for a live dashboard if possible. Some agencies use Google Data Studio or Looker; others provide PDFs. Decide what works for you.

Caveat: These are illustrative targets. Actual numbers depend on your industry, competition, and starting point. A responsible agency will set realistic targets after an initial audit, not before.

5. Include a Risk Assessment Section

This is the part most briefs skip—and the part that saves you from expensive mistakes. Ask the agency to address:

• What happens if a redirect is wrong? A 301 pointing to a 404 can tank ranking signals. The agency should have a redirect mapping process and a QA step.
• How do they handle duplicate content? If they’re rewriting product descriptions, do they have a style guide? If they’re using canonical tags, do they audit them regularly?
• What’s their stance on Core Web Vitals? Performance improvements can break functionality. Ask for a staging environment test before pushing changes live.
• How do they handle penalties? If a manual action happens (even if it’s not their fault), what’s the remediation process? A good agency has a documented recovery workflow.

Example risk scenario: An agency runs a link building campaign using automated outreach to low-quality directories. Six months later, Google issues a manual action for unnatural links. Your traffic drops 80%. The agency says “we didn’t know.” Your brief should prevent this by requiring the agency to disclose their link acquisition methods upfront.

6. Clarify the Deliverables Timeline

A brief without a timeline is a wishlist. Define what “done” looks like for each phase:

• Phase 1: Technical Audit (Weeks 1–2). Deliverable: Audit report with prioritized issues (critical, high, medium, low).
• Phase 2: On-Page Optimization (Weeks 3–6). Deliverable: Optimized meta tags, content updates, and keyword mapping document.
• Phase 3: Link Building & Performance (Ongoing). Deliverable: Monthly link acquisition report and Core Web Vitals improvement log.

Be realistic. A full technical audit for a 500-page site takes more than a week. On-page optimization for an e-commerce site with 10,000 product pages takes months. Your brief should acknowledge this and ask for a phased approach.

7. The Final Checklist: What to Send the Agency

Before you hit send on your brief, run through this checklist:

• Current crawl budget data (or note that it’s unknown)
• Core Web Vitals scores (LCP, CLS, INP)
• XML sitemap URL and last update date
• robots.txt content
• Canonical tag strategy (or lack thereof)
• Duplicate content known issues
• Backlink profile report (Majestic, Ahrefs, or SEMrush)
• Keyword research existing documents (if any)
• Content strategy current state (what exists, what’s missing)
• Risk tolerance statement (black-hat vs. white-hat)
• Reporting preferences (dashboard vs. PDF, monthly vs. weekly)
• Timeline expectations (phases and deliverables)

Summary: A well-written brief doesn’t just get you better proposals—it filters out the agencies that overpromise and underdeliver. By including technical baselines, risk assessments, and clear deliverables, you signal that you’re an informed client who won’t accept shortcuts. The agencies that respond with thoughtful, data-driven plans are the ones worth hiring. The ones that respond with “we’ll get you to page one in 30 days” are the ones to avoid.
