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

You’re about to hire an SEO agency, and you want results—not promises. The problem? Most briefs are vague, stuffed with buzzwords like “increase traffic” or “rank for X,” and leave the agency guessing what you actually need. That’s how you end up with a generic audit that misses your site’s core issues or a link-building campaign that gets you penalized. This checklist is your guide to writing a brief that gets the right work done—starting with technical SEO audits, moving through on-page optimization, and ending with performance metrics that matter.

1. Start with a Technical SEO Audit Brief That Actually Diagnoses Problems

A technical SEO audit isn’t a one-time checklist; it’s a systematic review of how search engines crawl, index, and render your site. If you brief an agency without specifying what you want audited, they’ll likely default to surface-level checks—like missing meta descriptions—while ignoring deeper issues like crawl budget waste or server-side rendering problems.

What to include in your audit brief:

• Crawlability and indexation scope: Specify that you want a full crawl of your site using a tool like Screaming Frog or Sitebulb. Ask for a breakdown of which pages are indexed versus those blocked by `robots.txt` or noindex tags. For example, if you have a large e-commerce site, the agency should check if your `robots.txt` accidentally blocks product pages or if your XML sitemap includes outdated URLs.
• Core Web Vitals analysis: Don’t just ask for “improve speed.” Request a report on LCP (Largest Contentful Paint), CLS (Cumulative Layout Shift), and FID/INP (First Input Delay / Interaction to Next Paint). These metrics directly impact user experience and Google’s ranking system. A good agency will use real-user data from Chrome User Experience Report (CrUX) and lab data from Lighthouse.
• Duplicate content and canonicalization: Ask the agency to identify pages with near-identical content and check whether canonical tags are implemented correctly. For instance, if you have HTTP and HTTPS versions of the same page, or `www` and non-www versions, the canonical tag should point to the preferred URL. Without this, search engines can split ranking signals across duplicates.
• Crawl budget optimization: This is critical for large sites (10,000+ pages). Brief the agency to analyze how Googlebot spends its crawl budget. Are low-value pages (like filter combinations or session URLs) consuming crawl slots that should go to product or category pages? The agency should recommend blocking irrelevant parameters via `robots.txt` or using nofollow on paginated pages.

2. Specify On-Page Optimization Beyond Meta Tags

Many briefs stop at “optimize title tags and meta descriptions.” That’s table stakes. A serious on-page optimization brief should cover content structure, keyword placement, and technical elements like heading hierarchy and schema markup.

Key elements to include:

• Keyword research and intent mapping: Don’t just list target keywords. Ask the agency to map keywords to search intent—informational, navigational, commercial, or transactional. For example, “best SEO tools” is commercial intent, while “what is SEO” is informational. Each intent requires a different page type and content format. A good agency will deliver a keyword map that aligns with your site’s existing pages or suggests new pages.
• Content strategy alignment: Brief the agency to evaluate existing content for relevance, freshness, and depth. They should identify thin content pages (under 300 words with no unique value) and recommend consolidation or rewriting. If you have a blog, ask for a content gap analysis—what topics are competitors covering that you aren’t?
• Technical on-page elements: Specify that you want a review of H1-H6 hierarchy, image alt text, internal linking structure, and schema markup (e.g., Product, FAQ, Article). For instance, if you run a recipe site, missing Recipe schema means your content won’t appear in rich results like carousels or star ratings.
• Internal linking optimization: Ask the agency to map your current internal link structure and suggest improvements. They should prioritize linking from high-authority pages to low-traffic pages that have strong content but weak visibility. A common mistake is linking only from navigation menus; a good brief will request contextual links within body copy.

3. Brief Link Building with Risk Awareness

Link building is where most SEO campaigns go wrong. Black-hat tactics—like buying links from private blog networks (PBNs) or using automated outreach—can trigger manual penalties from Google. Your brief should explicitly exclude these and focus on white-hat, sustainable methods.

What to specify in your link-building brief:

• Backlink profile analysis first: Before any outreach, the agency should audit your current backlink profile using tools like Ahrefs or Majestic. They need to identify toxic links (spammy domains, irrelevant sites, or links from link farms) and plan a disavow file if necessary. This prevents existing bad links from dragging down your Domain Authority or Trust Flow.
• Link acquisition methods: Define acceptable tactics—guest posting on relevant industry blogs, broken link building (finding dead links on authoritative sites and suggesting your content as a replacement), or resource page outreach (getting listed on curated resource pages). Reject any tactic that involves paying for links directly or using automated tools.
• Metrics to track: Don’t just ask for “more backlinks.” Request a report on referral domains gained, domain rating (DR) of linking sites, and Trust Flow (TF) scores. A single link from a high-TF site (e.g., a .edu or .gov domain) is worth more than 50 low-quality links. Also, track the ratio of dofollow to nofollow links—a natural profile has a mix.
• Risk mitigation: Include a clause in your brief that the agency must provide a list of target domains for your approval before outreach. This ensures you have visibility into who they’re contacting. Also, ask for a monthly report on any penalties or manual actions flagged in Google Search Console.

Common black-hat tactics to avoid:

• Buying links from PBNs or link brokers
• Using automated comment spam with links
• Exchanging links excessively (reciprocal linking schemes)
• Using hidden links or paid links without `nofollow` or `sponsored` attributes

4. Set Performance Metrics That Go Beyond Rankings

Rankings are vanity metrics without context. A page that ranks #1 for a low-volume keyword might drive less traffic than a page ranking #5 for a high-volume term. Your brief should define success in terms of organic traffic, conversion rates, and user engagement.

Performance metrics to include in your brief:

• Organic traffic growth: Specify a baseline (e.g., current monthly organic sessions) and a target percentage increase over 6–12 months. But be realistic—SEO takes time, especially for competitive niches.
• Core Web Vitals improvement: Set specific thresholds—LCP under 2.5 seconds, CLS under 0.1, and FID under 50ms (or INP under 200ms). The agency should provide before-and-after data from CrUX.
• Conversion rate optimization (CRO) from organic traffic: Ask the agency to track goal completions (e.g., form submissions, purchases, sign-ups) from organic visits. If traffic increases but conversions don’t, the content or user experience needs work.
• Indexation and crawl stats: Request monthly reports on pages indexed in Google, crawl requests per day, and any crawl errors (e.g., 404s, 500s). A healthy site should have a steady crawl rate and minimal errors.

5. Build a Reporting Cadence That Holds the Agency Accountable

Without a clear reporting structure, you’ll get vague updates like “we’re working on it.” Your brief should specify what reports you want, how often, and in what format.

Recommended reporting structure:

• Monthly reports: Include organic traffic trends, keyword ranking changes (for target terms), backlink profile changes, and Core Web Vitals scores. Use a dashboard tool like Google Data Studio or Looker Studio for easy visualization.
• Quarterly deep dives: A comprehensive audit of technical SEO, content performance, and link building progress. This is where you review the crawl budget analysis, duplicate content fixes, and any algorithm update impacts.
• Ad-hoc alerts: The agency should notify you immediately if they detect a penalty, a major drop in traffic, or a critical technical issue (e.g., site down, robots.txt blocking entire site).

Final Checklist for Your SEO Agency Brief

Before you send your brief, run through this checklist:

• Have you defined the scope of the technical SEO audit (crawlability, Core Web Vitals, duplicate content, crawl budget)?
• Did you specify on-page optimization requirements beyond meta tags (keyword intent mapping, content strategy, schema markup)?
• Did you include a clear link-building policy that excludes black-hat tactics?
• Have you set measurable performance metrics (organic traffic, Core Web Vitals, conversion rates)?
• Did you outline a reporting cadence (monthly, quarterly, ad-hoc)?
• Have you included a clause for risk mitigation (approval of link targets, penalty monitoring)?

A well-written brief doesn’t just ask for “SEO services.” It tells the agency exactly how to diagnose your site, what tactics to use, and how to measure success—while protecting you from risky practices. Use this checklist, and you’ll get a campaign that’s focused, transparent, and built for long-term results.
