How to Use OpenClaw for SEO Content Audits on WordPress Sites

Last Tuesday, while running an SEO audit on a WordPress site with OpenClaw, I hit a wall: requests timing out halfway through, content extraction cutting off mid-article, posts vanishing from results. The problem became clear once I dug into the logs—the WordPress REST API was paginating aggressively, and the bloated HTML responses from the theme’s feature-rich components exceeded OpenClaw’s default fetch window. This guide walks you through the configuration changes that fixed it.

Understanding the WordPress REST API for Content Audits

OpenClaw interacts with your WordPress site through its REST API, specifically the /wp/v2/posts and /wp/v2/pages endpoints. By default, these endpoints return a limited number of posts per request (typically 10, up to a maximum of 100). For an audit of hundreds or thousands of posts, this means many sequential API calls, each introducing network overhead and latency. Furthermore, the content returned by default is often a stripped-down version—you might need the full HTML to properly assess SEO factors like heading structure, image alt tags, internal link count, and schema markup. This requires modifying the API request parameters.

When you configure a data source for a WordPress site, OpenClaw queries these endpoints with whatever defaults it ships with. A common mistake is to rely solely on the default content fields, which omit critical SEO data. For comprehensive SEO analysis, you need the full rendered HTML. This is achievable by requesting the content.rendered field and potentially other custom fields your theme or plugins might expose—for example, Yoast SEO exposes yoast_head_json, which contains meta descriptions and focus keywords. However, fetching full HTML for many posts can lead to response bodies exceeding 50–100 MB for large sites, which strains both your OpenClaw instance and your WordPress server.

Configuring OpenClaw for Efficient WordPress Data Extraction

To optimize OpenClaw for WordPress audits, you need to adjust two main areas: the data source configuration and the underlying fetcher settings. The primary goal is to minimize API calls and ensure you get the complete content you need without overwhelming either system.

Add the following configuration to your .openclaw/config.json under the "data_sources" section for your WordPress site. Replace "your_wordpress_site" with the actual ID you’ve given your data source:

{
  "data_sources": {
    "your_wordpress_site": {
      "type": "wordpress",
      "url": "https://your-wordpress-domain.com",
      "fetch_strategy": {
        "posts_per_page": 100,
        "include_fields": [
          "id",
          "slug",
          "title.rendered",
          "content.rendered",
          "link",
          "modified",
          "date",
          "yoast_head_json"
        ]
      },
      "rate_limit": {
        "requests_per_second": 2
      },
      "custom_headers": {
        "User-Agent": "OpenClaw/SEO-Audit"
      },
      "timeout": 30,
      "max_retries": 3
    }
  }
}

The key settings here are: posts_per_page: 100 reduces API calls by a factor of 10 compared to the default 10-post pagination; include_fields explicitly requests only the fields you need for SEO analysis, reducing payload bloat; requests_per_second: 2 prevents hammering your WordPress server while still moving at a reasonable pace; timeout: 30 gives the server 30 seconds to respond before OpenClaw abandons the request (increase to 60 if you have a particularly slow server); and max_retries: 3 ensures temporary network hiccups don’t kill the entire audit.

Optimizing Your WordPress Server for OpenClaw Audits

Configuration changes alone won’t solve timeout issues if your WordPress server itself is slow. On the WordPress side, you have three levers to pull. First, disable unnecessary plugins during the audit window. A site running Akismet, WooCommerce, and five ad-network plugins will serve REST responses 40–60% slower than one running only essential plugins. If you can’t disable them, at least temporarily reduce the number of hooks they execute on REST requests by adding this to your wp-config.php:

if ( defined( 'REST_REQUEST' ) && REST_REQUEST ) {
    define( 'DONOTCACHEPAGE', true );
}

Second, cache REST responses aggressively. Install a plugin like WP Super Cache ($0, free; or WP Rocket at $39/year) and enable REST API caching. This prevents repeated requests for the same posts from hitting the database every time. Third, optimize your database queries. If you’re running WordPress 5.8 or later, enable lazy-loading for post meta by going to Settings → Permalinks and saving (this flushes the cache and can improve REST performance). For older installs, query only the post types you need in your OpenClaw config—don’t fetch posts, pages, custom post types, and attachments all at once.

Handling Large Content and Incomplete Extraction

Even with optimized API settings, very long posts (over 100,000 characters) can still cause timeouts. If you notice that extraction stops partway through certain articles, modify the fetch_strategy in your config to split the work:

{
  "fetch_strategy": {
    "posts_per_page": 50,
    "batch_size": 5,
    "content_max_length": 50000,
    "truncate_incomplete": false
  }
}

Here, batch_size: 5 tells OpenClaw to process 5 posts at a time (instead of attempting all 100 sequentially), giving your server breathing room; content_max_length: 50000 caps individual post content at 50 KB (still plenty for SEO analysis, which rarely needs the full 500 KB behemoth); and truncate_incomplete: false ensures OpenClaw logs a warning if it truncates content, rather than silently dropping data.

Network and Infrastructure Considerations

If your WordPress server and OpenClaw instance are in different regions or behind slow connections, network latency will compound timeout issues. Run a quick test: from your OpenClaw server, curl the WordPress REST API endpoint directly and time the response:

time curl -H "User-Agent: OpenClaw" "https://your-wordpress-domain.com/wp-json/wp/v2/posts?per_page=100"

If this takes more than 5 seconds, your WordPress server or network is the bottleneck. In that case, consider moving OpenClaw closer to your server (same hosting provider or region), or use a CDN that caches REST responses (Cloudflare, at $20/month for Pro, does this with a bit of configuration).

Testing and Monitoring

After making these changes, test a small batch first. Configure OpenClaw to audit just 10–20 posts, monitor the logs, and watch response times:

{
  "data_sources": {
    "your_wordpress_site": {
      "test_mode": true,
      "max_posts": 20
    }
  }
}

Once responses are consistently under 5 seconds per batch, remove test_mode and scale up. If you still see timeouts with these settings in place, the issue is likely on your WordPress server itself—check CPU usage during audits (aim for under 70%), memory availability (at least 512 MB free), and slow query logs (queries taking over 2 seconds are usually the culprit).
