How to Brief an SEO Agency for Technical SEO & Site Health: A Practical Checklist

You’re about to hand over your website to an SEO agency, and you’ve heard the horror stories: black-hat links that trigger penalties, redirect chains that kill crawl budget, or a “technical audit” that’s just a list of missing meta descriptions. You want sustainable growth, not a quick fix that backfires. Here’s how to brief an agency so you get expert technical SEO and site health services—without the fluff.

1. Start with the Crawl Budget and Site Architecture

Before any optimization, the agency needs to understand how search engines interact with your site. Crawl budget—the number of pages Googlebot will crawl in a given timeframe—isn’t infinite. If your site has thousands of thin pages, broken links, or duplicate content, that budget gets wasted.

What to include in your brief:

• Total page count (including archived, staging, or test pages).
• Known crawl issues from Google Search Console (e.g., 404s, soft 404s, or redirect loops).
• Current XML sitemap structure and robots.txt file.
• Any recent site migrations or platform changes.

Checklist for the agency:

• Audit crawl budget allocation using server logs (not just GSC data).
• Review robots.txt for accidental blocking of critical pages (e.g., CSS, JS, or product pages).
• Validate XML sitemaps: are they indexable, error-free, and prioritized by page importance?
• Identify and eliminate duplicate content through proper canonicalization.

> Risk alert: A common mistake is blocking Googlebot from resources like JavaScript or CSS files. This can break rendering and hurt Core Web Vitals. Always test robots.txt with the Google Robots Testing Tool.

2. Demand a Core Web Vitals Baseline

Core Web Vitals (LCP, CLS, FID/INP) are considered by Google as part of user experience signals. An agency that skips this step is ignoring a fundamental user experience metric. Your brief should ask for a current baseline and a target improvement plan.

What to specify:

• Current LCP values (ideally under 2.5 seconds).
• CLS score (target below 0.1).
• INP (Interaction to Next Paint) under 200 milliseconds.
• Device breakdown: mobile vs. desktop performance.

The agency should provide a timeline for improvements and explain trade-offs (e.g., compressing images might reduce visual quality).

3. Clarify the Noindex and Nofollow Strategy

Your brief must explicitly address how the agency handles noindex tags and nofollow attributes. Mismanagement here can lead to index bloat or lost ranking signals.

Key questions to include:

• Which pages should be noindexed (e.g., filter pages, paginated archives, or thank-you pages)?
• Are they using `noindex` via robots meta tags, X-Robots-Tag, or both? (Learn more in our guide on robots meta tags and X-Robots-Tag.)
• How will they handle nofollow on external links? Do they use `rel="sponsored"` for paid links? (See sponsored links content for best practices.)

Checklist for the agency:

• Audit all current noindex directives for accuracy.
• Confirm noindex is never applied to important landing pages.
• Document a nofollow policy: when to use `nofollow`, `sponsored`, or `ugc`.
• Avoid common pitfalls like noindex tag mistakes on canonicalized pages.

> Risk alert: Applying noindex to pages that have external backlinks can waste link equity. Always weigh the indexation decision against your link profile.

4. Set Expectations for Link Building and Backlink Profile

Link building is often where agencies overpromise and underdeliver—or worse, use black-hat tactics. Your brief should require a transparent strategy for link building and backlink profile management.

What to demand:

• A clear distinction between white-hat (guest posts on relevant sites, broken link building) and gray-hat (paid links with no disclosure) tactics.
• A plan for disavowing harmful links using Google’s Disavow Tool.
• Regular reporting on link profile metrics (such as domain-level authority scores from third-party tools) and trust flow indicators.

Checklist for the agency:

• Provide a list of target domains for outreach (with relevance scores).
• Show examples of past successful link placements (without naming clients).
• Explain how they monitor your backlink profile for toxic links.
• Avoid any tactic that promises “guaranteed first page ranking” or “instant SEO results.”

5. Define the On-Page Optimization and Content Strategy

On-page optimization isn’t just about keyword stuffing. It’s about intent mapping—aligning content with what users actually search for. Your brief should request a content strategy that addresses search intent and avoids duplicate content.

What to include:

• A list of target keywords (from your keyword research).
• The search intent for each keyword (informational, navigational, transactional).
• A content calendar for new pages and updates to existing ones.
• Guidelines for internal linking to distribute link equity.

Checklist for the agency:

• Audit existing content for duplication (use tools like Copyscape or Siteliner).
• Map each target keyword to a specific page (avoid cannibalization).
• Optimize title tags, meta descriptions, and header tags without over-optimization.
• Ensure all internal links use descriptive anchor text (not “click here”).

> Risk alert: Duplicate content from thin or scraped pages can lead to indexation issues. Always canonicalize or consolidate such pages.

6. Address External Link Quality and Sponsored Content

External links—both outbound and inbound—affect your site’s trustworthiness. Your brief should ask how the agency evaluates external link quality and handles sponsored links.

Questions to include:

• How do they vet external links in your content? (See external link quality for criteria.)
• Do they use `rel="sponsored"` for any paid or affiliate links?
• How do they handle broken external links (404s or redirects)?

Checklist for the agency:

• Audit all outbound links for relevance and authority.
• Add `nofollow` or `sponsored` attributes where appropriate.
• Set up a regular check for broken external links (monthly or quarterly).
• Document a policy for linking to low-quality or spammy sites.

7. Finalize Reporting and Communication

A good technical SEO agency provides transparent reporting. Your brief should define the metrics they’ll track and how often you’ll receive updates.

Key metrics to include:

• Organic traffic growth (by landing page and keyword).
• Indexation status (pages indexed vs. submitted).
• Core Web Vitals scores over time.
• Backlink profile changes (new links, lost links, toxic links).
• Crawl errors and their resolution status.

Communication cadence:

• Weekly: brief email with key changes (e.g., new content published, technical fixes implemented).
• Monthly: detailed report with charts and recommendations.
• Quarterly: strategy review and roadmap for the next quarter.

Summary: What a Good Brief Looks Like

A well-structured brief for technical SEO and site health services should:

• Define your current site status (crawl budget, Core Web Vitals, backlink profile).
• Specify the agency’s approach to noindex, nofollow, and canonicalization.
• Demand a transparent link building strategy with no black-hat tactics.
• Require a content strategy based on intent mapping and duplicate content prevention.
• Set clear reporting expectations and communication cadence.

By following this checklist, you’ll avoid agencies that promise “instant SEO results” or “guaranteed first page ranking.” Instead, you’ll get sustainable growth through expert technical SEO and site health services.
