Using Opus 4.7's 1M Context to Audit a Whole Site at Once

The Problem: Per-Page Audits Don't Scale

You built something. It works. Users love it. But nobody knows it exists.

You've tried the traditional SEO audit route. You ran Ahrefs. You got a 50-page PDF full of recommendations you'll never implement. Or worse—you paid an agency $5K to tell you what you already knew: your site needs better content and faster load times.

The real problem isn't what's broken. It's that traditional audits—whether automated tools or human strategists—analyze your site page by page. They miss the forest. They can't see how your homepage relates to your blog, how your pricing page connects to your FAQ, how your entire information architecture either reinforces or undermines your core message.

That's where Opus 4.7 changes everything.

Claude Opus 4.7 has a 1M token context window. That's roughly 750,000 words. You can feed it your entire site—all your pages, all your content, all your structure—in a single request. And it will analyze it holistically, catching cross-page issues, brand inconsistencies, and keyword gaps that no per-page tool ever will.

This guide walks you through exactly how to do it. No agency. No waiting. No per-page limits.

Prerequisites: What You Need Before You Start

Before you dump your site into Opus 4.7, you need three things:

1. A Claude Opus 4.7 API account — You'll need access to Claude Opus 4.7 via Anthropic's platform. If you're using the web interface (claude.ai), you can also paste content directly, but the API gives you more control and the ability to handle larger payloads without hitting interface limits.

2. Your site content in a single document — You'll need to export your site's HTML, markdown, or plain text. This is the critical step. You're not submitting individual pages; you're submitting your entire site as one continuous text file. We'll cover the extraction process in detail below.

3. A clear audit scope — Decide what "your site" means. Are you auditing:

Your main website only (excluding blog)?
Your main site + blog?
Your entire domain, including docs, help center, and landing pages?
Specific sections you want to focus on?

For most founders, "main site + blog" is the sweet spot. It's comprehensive without being overwhelming. If your site is massive (10,000+ pages), you'll need to segment it into logical chunks—product docs in one audit, marketing site in another.

Step 1: Extract Your Entire Site Content

This is the unglamorous but critical first step. You need to get all your site content into a single text file that Opus 4.7 can consume.

Option A: Use a Web Scraper (Fastest for Most Sites)

If your site is under 500 pages, use a web scraper to pull all content at once.

Using Screaming Frog SEO Spider (desktop tool, free up to 500 URLs):

Download Screaming Frog SEO Spider
Enter your domain
Click "Start" and let it crawl your entire site
Go to Reports → Custom → HTML and select all text content columns
Export as CSV
Use a simple Python script or Google Sheets to combine all text into a single markdown file

Using a headless browser approach (if you need JavaScript-rendered content):

If your site uses client-side rendering (Next.js, React, Vue), Screaming Frog might miss content. Use Playwright or Puppeteer:

npm install playwright

Then write a simple script to crawl your domain and save all text content. This approach is detailed in Anthropic's documentation on handling large content volumes.

Option B: Export from Your CMS (Easiest if Available)

If you use WordPress, Ghost, or another CMS:

WordPress: Use the All in One SEO export or WP All Export to pull all posts and pages
Ghost: Use the Ghost API to export all posts as JSON, then convert to markdown
Webflow: Export your site as static HTML via their export feature
Notion: If your site is Notion-based, export all pages as markdown

Option C: Manual Compilation (For Smaller Sites)

If you have fewer than 50 pages, copy-paste into a single document. Include:

Page title
Page URL
Meta description
H1 and H2 headings
Body content
Internal links
CTA buttons and text

Format it consistently. Each page should be clearly separated.

Formatting Your Content for Opus 4.7

Once you have all your content, format it for clarity. Opus 4.7 will parse any format, but structured markdown makes analysis easier:

# Homepage
URL: https://yoursite.com
Meta: Your meta description here

Your homepage content here.

---

# About Page
URL: https://yoursite.com/about
Meta: About us meta description

Your about page content here.

---

Include:

Page title (H1)
URL
Meta description
All body content
Internal links (with anchor text and target URL)
Call-to-action buttons
Clear page separators (use ---)

Keep it plain text. Don't include CSS, JavaScript, or images. Opus 4.7 reads text, not visual design.

Pro tip: If your site is over 500 pages, check your token count before submitting. Anthropic's token calculator shows exactly how many tokens your content will consume. Most sites under 1M tokens fit comfortably. If you're over 1M tokens, segment by section (marketing site, product docs, blog separately).

Step 2: Prepare Your Audit Prompt

Now you need to tell Opus 4.7 what to look for. A vague prompt like "audit my site" will produce generic recommendations. A specific prompt will produce actionable insights.

Here's the audit prompt structure that works:

You are an expert SEO auditor and AI Engine Optimization strategist. 
I'm providing my entire website content below. Analyze it holistically.

Focus on:

1. BRAND POSITIONING: Is my core value proposition clear and consistent across all pages? Do I repeat the same message or contradict myself?

2. KEYWORD STRATEGY: What keywords do I target implicitly? Are there gaps? Am I competing with myself (cannibalization)?

3. CONTENT STRUCTURE: Do my pages follow a logical hierarchy? Can a visitor understand my product/service from the homepage alone?

4. INTERNAL LINKING: Are my internal links strategic or random? Do they guide users toward conversion?

5. AI CITATION POTENTIAL: Which of my pages are most likely to be cited by Claude, ChatGPT, or Perplexity? Why? What's missing?

6. TECHNICAL CLARITY: Are my meta descriptions compelling? Do my H1 tags match user intent? Are my CTAs clear?

7. TOPICAL AUTHORITY: Do I have enough depth in my core topics, or am I surface-level?

8. COMPETITIVE POSITIONING: Based on my content, who am I positioned against? Is that intentional?

Provide specific, actionable recommendations for each section. Reference exact page titles and URLs. Avoid generic advice.

You can customize this based on your priorities. If you're a SaaS founder, focus on #2, #3, and #4. If you're building topical authority, focus on #7.

Step 3: Submit Your Site to Opus 4.7

Via the Claude Web Interface (Simplest)

Go to claude.ai
Start a new conversation
Paste your audit prompt first
Then paste your entire site content
Hit send

The web interface has no hard limit on input size (within the 1M token window), so this works for most sites.

Important: If your content is very large (800K+ tokens), the web interface might time out. Use the API instead.

Via the Anthropic API (For Large Sites or Automation)

If you're auditing regularly or your site is massive, use the API:

import anthropic

client = anthropic.Anthropic(api_key="your-api-key")

with open("your_site_content.txt", "r") as f:
    site_content = f.read()

audit_prompt = """
You are an expert SEO auditor...
[Insert your audit prompt here]
"""

message = client.messages.create(
    model="claude-opus-4-7",
    max_tokens=8000,
    messages=[
        {
            "role": "user",
            "content": f"{audit_prompt}\n\n{site_content}"
        }
    ]
)

print(message.content[0].text)

This approach:

Handles files larger than the web interface can paste
Lets you save results programmatically
Costs roughly $0.03-0.10 per audit depending on site size
Takes 30-90 seconds to complete

Check Anthropic's official documentation on using the API for the latest model names and pricing.

Step 4: Analyze the Results

Opus 4.7 will return a comprehensive audit covering all the areas in your prompt. Here's how to extract value:

Read for Patterns, Not Just Bullets

Opus 4.7 will identify specific issues, but the real insight is in the patterns. If it flags "unclear value proposition on homepage" and "vague meta descriptions on product pages," that's one problem: unclear positioning. Fix that once, and both issues disappear.

Prioritize by Impact

Not all recommendations are equal. Opus 4.7 will tell you what's wrong. You decide what matters most:

High impact (do first):

Brand positioning clarity (affects all pages)
Homepage messaging (first impression)
Core product/service pages
Internal linking structure

Medium impact (do second):

Meta description optimization
H1/H2 tag clarity
FAQ or help content
Blog post structure

Low impact (do last):

Minor copywriting tweaks
Formatting improvements
Secondary pages

Compare Against AI Citation Potential

One major advantage of using Opus 4.7 for audits: it tells you which pages are citation-worthy and which aren't. Learn more about how Claude Opus 4.7 cites sources differently than other models.

If Opus 4.7 says "your pricing page lacks specificity" or "your feature comparison is too generic," that's actionable. You now know exactly what to fix to get cited by AI search engines.

Step 5: Build Your Action Plan

Opus 4.7 gives you the diagnosis. Now you build the treatment plan.

Create a Prioritized Fix List

Take the audit results and create a spreadsheet:

Issue	Page	Impact	Effort	Priority	Owner	Deadline
Unclear value prop	Homepage	High	Low	1	You	This week
Missing internal links	Product page	Medium	Low	2	You	Next week
Thin content	Blog archive	Low	High	5	Later	Later

Focus on high-impact, low-effort fixes first. You'll see results faster and build momentum.

Batch Content Updates

If Opus 4.7 recommends updating multiple pages' meta descriptions, do them all at once. Same with H1 tags, internal linking, or CTA copy.

This is where you gain an advantage over agencies. You can implement changes in hours, not weeks.

Re-Audit After 30 Days

After you've implemented major changes, run another full-site audit. Feed the updated content to Opus 4.7 again. You'll see:

Whether your fixes actually improved clarity
New issues that emerged
Remaining gaps

This iterative approach beats one-time audits. You're building SEO as a continuous process, not a project.

Pro Tips: Getting More Value From Opus 4.7 Audits

Tip 1: Segment by Audience or Product Line

If you have multiple products or serve different audiences, run separate audits:

Audit #1: Homepage + product pages for your main offering
Audit #2: Blog + thought leadership content
Audit #3: Docs + help content

This gives you focused recommendations instead of generic site-wide advice.

Tip 2: Include Competitor Content

For a competitive analysis, paste your competitor's top pages alongside yours:

# YOUR SITE
[your content]

---

# COMPETITOR A
[competitor content]

---

# COMPETITOR B
[competitor content]

Then ask: "Compare these three sites. What are the structural and messaging differences? Which is clearest? Most persuasive? Best for AI citations?"

Opus 4.7 will identify exactly what your competitors do better—and what you do better.

Tip 3: Use the Audit to Brief Your Content Team

If you have writers, designers, or marketers, use the Opus 4.7 audit as your content strategy document. It's more specific than any agency brief and costs $0.10 instead of $2,000.

Learn how to use Opus 4.7 audit findings to create content briefs that produce rankable posts.

Tip 4: Track Changes Over Time

Save each audit as a dated file:

site-audit-2025-01-15.txt
site-audit-2025-02-15.txt
site-audit-2025-03-15.txt

After three audits, you'll see whether your changes are working or whether you're chasing the wrong problems.

Tip 5: Ask Follow-Up Questions

Don't treat the initial audit as final. Use the same conversation thread to ask clarifications:

"You mentioned my pricing page is too generic. What specific details should I add?"
"How would you restructure my homepage to be clearer?"
"Which of these pages should I prioritize rewriting?"

Opus 4.7 has your entire site in context, so follow-ups are specific and relevant.

Common Mistakes (and How to Avoid Them)

Mistake 1: Submitting Unstructured Content

The problem: Pasting raw HTML or unformatted text makes it hard for Opus 4.7 to distinguish pages.

The fix: Use the markdown format from Step 1. Clear page separators. Consistent structure.

Mistake 2: Asking Vague Questions

The problem: "Audit my site" produces generic recommendations.

The fix: Use the specific prompt from Step 2. Tell Opus 4.7 exactly what you care about.

Mistake 3: Ignoring Cross-Page Issues

The problem: Treating each recommendation as isolated.

The fix: Look for patterns. If multiple pages have similar issues, there's usually one root cause.

Mistake 4: Not Re-Auditing After Changes

The problem: Implementing fixes and assuming they worked.

The fix: Run a new audit 30 days later. Verify improvements. Identify new gaps.

Mistake 5: Submitting Too Much Content

The problem: Including pages that don't matter (old landing pages, archived blog posts, duplicate content).

The fix: Clean your site first. Remove or redirect old content. Include only active pages.

How This Compares to Traditional Audits

Let's be direct about what you're gaining:

Traditional SEO Agency Audit:

Cost: $3,000–$10,000
Timeline: 2–4 weeks
Depth: Per-page analysis (misses cross-page patterns)
Actionability: Often vague ("improve content", "build backlinks")
Follow-up: Requires more consultations (more fees)

Ahrefs/Semrush Audit:

Cost: $99–$400/month
Timeline: Instant
Depth: Technical metrics only (doesn't understand your positioning)
Actionability: Mostly alerts (broken links, missing tags)
Follow-up: You interpret the data yourself

Opus 4.7 Whole-Site Audit (this approach):

Cost: $0.03–$0.15 per audit
Timeline: 30–90 seconds
Depth: Holistic (catches cross-page issues, positioning gaps, messaging inconsistencies)
Actionability: Specific recommendations tied to exact pages
Follow-up: Instant clarifications in the same conversation

The trade-off: Opus 4.7 doesn't crawl your site for technical issues (broken links, slow load times, crawl errors). You still need a tool like Google Search Console or Screaming Frog for that. But for strategic SEO—positioning, messaging, content gaps, internal linking—Opus 4.7 beats everything else at 1/100th the cost.

Understand the difference between AI Engine Optimization and traditional SEO to know when each approach matters.

Step 6: Implement Changes and Measure Results

An audit is worthless without implementation. Here's how to actually ship:

Week 1: Quick Wins

Implement the high-impact, low-effort fixes from your priority list:

Rewrite your homepage headline
Update meta descriptions on key pages
Fix broken internal links
Clarify your main CTA

These take hours, not days. Do them yourself. Don't wait for approval or perfect wording.

Week 2–3: Content Rewrites

Tackle the pages Opus 4.7 flagged as unclear or thin:

Product/service pages
Core landing pages
FAQ or help sections

Use the blog post structure that gets cited by AI search engines to rewrite these pages. If you have a blog, start there—it's usually the easiest content to improve.

Week 4+: Monitor and Iterate

Watch for:

Traffic changes (Google Analytics)
Ranking changes (Google Search Console)
AI citations (check Claude, ChatGPT, Perplexity for your domain)

After 30 days, run another Opus 4.7 audit. Compare results. Adjust.

The Bigger Picture: Opus 4.7 as Your SEO Baseline

This audit approach isn't a one-time thing. It's your new baseline.

Every time you add significant content (new product pages, major blog posts, documentation), feed it to Opus 4.7 with a simple prompt: "Does this fit with my existing site positioning? Any gaps or inconsistencies?"

Learn how Opus 4.7 reads your site differently than ChatGPT to optimize for AI citations as you build.

This keeps your site coherent and strategic without needing an expensive strategist or agency.

When You Need More Than an Audit

Opus 4.7 audits are powerful, but they're diagnostic. If you need:

100 AI-generated blog posts to build topical authority fast, use Seoable's AI blog generation (100 posts + domain audit + keyword roadmap in 60 seconds for $99)
Detailed keyword research beyond what Opus 4.7 provides, combine it with Ahrefs or SEMrush
Technical SEO fixes (Core Web Vitals, crawlability, schema), use Screaming Frog or Google Search Console
Backlink strategy, you still need outreach or tools like Pitchbox

Opus 4.7 audits are the foundation. They tell you what's strategically wrong. Other tools fix the technical and tactical details.
