Setup a Reverse Proxy for Automated Blogging with CMO.so: Nginx & Shopify Guide

Introduction: Seamless Subfolder Blogging for Peak Visibility

Serving your WordPress blog under a subdirectory on the same domain as your Shopify store can supercharge how Google sees your content. A well-configured reverse proxy bridges the gap between Shopify and WordPress, so all your blog pages sit neatly under /blog. That means link equity flows straight to your main site. No more subdomain confusion, no more SEO splits.

But setting up a reverse proxy isn’t just about pointing Nginx or a CDN at two different servers. You need to guard against Shopify’s bot detection, nail SSL certificate renewals, and optimise every URL and header for WordPress subdirectory SEO. In this guide, we’ll walk through each step, share real-world tips and pitfalls, and show how CMO.so’s fully automated AI-driven platform can scale your content output without manual wrangling.

Why Serving a Blog in a Subdirectory Boosts SEO

When you place your WordPress blog on a subdomain (e.g. blog.example.com), Google treats it as a separate site. You dilute your domain authority. A subdirectory (example.com/blog) inherits that link juice, so:

• Your homepage rankings benefit from every blog share.
• Internal links strengthen your main site’s topical relevance.
• User trust grows when navigation feels seamless.

For merchants, combining Shopify’s e-commerce engine with WordPress’s flexibility is a powerful blend. You keep store features intact, but map all traffic and engagement back to one domain. That’s the secret sauce for optimal WordPress subdirectory SEO.

Reverse Proxy Fundamentals

What Is a Reverse Proxy?

Think of a reverse proxy as a traffic officer. Visitors always see your main URL, but the proxy quietly reroutes requests to the correct backend:

• / or /shop → Shopify
• /blog and /blog/* → WordPress server

Nginx or a CDN like AWS CloudFront can play this role. It handles SSL, caching and hides your server details from prying bots.

Benefits for Shopify + WordPress

1. Consolidated analytics: One property in Google Analytics.
2. Simplified SSL management: Single certificate for your domain.
3. Enhanced user experience: Consistent site look and feel.
4. Stronger SEO: One domain, more authority, improved rankings.

Step-by-Step Guide: Nginx Proxy Setup

Prerequisites

• A server (VPS or dedicated) with Nginx installed.
• Two DNS records:
• example.com → Nginx IP (A record)
• blog.example.com → WordPress IP (A record)
• Shopify store already live on example.com.
• Valid SSL certificate (Let’s Encrypt or commercial) covering both hostnames.

Basic Nginx Configuration

In your Nginx sites-available file:

server {
    listen 443 ssl;
    server_name example.com;

    # SSL certs
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;

    # Proxy Shopify for root
    location / {
        proxy_pass https://shops.myshopify.com;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }

    # Proxy WordPress for /blog
    location /blog/ {
        proxy_pass https://blog.example.com/;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

Key points:

• Host header must remain example.com.
• Adjust proxy_pass URL to match your WordPress server.
• Ensure trailing slashes to avoid redirect loops.

SSL and SNI Considerations

Shopify requires SNI support. In Nginx, use:

ssl_protocols TLSv1.2 TLSv1.3;
ssl_prefer_server_ciphers on;

If you’re placing a CDN in front of Shopify, set the origin protocol policy to Match Viewer and enable SNI for both auto-renewal and proper domain validation.

Integrating AWS CloudFront for Bot Avoidance

Shopify’s anti-bot system can sometimes flag proxy requests. Enter CloudFront—a global CDN with a large server pool that blends requests, mitigating bot detection.

CloudFront Distribution Setup

1. Create a distribution with two origins:
   – Shopify origin: shops.myshopify.com
   – Blog origin: blog.example.com
2. Define cache behaviours:
   – /blog* routes to Blog origin.
   – Default routes to Shopify.
3. Use SNI TLS and set Origin Protocol Policy to Match Viewer for Shopify.

Path-Based Behaviours

• Behaviour 1: Path pattern /blog* → Blog origin
• Behaviour 2: Path pattern * → Shopify origin

This mirrors our Nginx setup but leverages CloudFront’s edge caching and IP diversity.

Common Pitfalls

• 403 Errors: Often a DNS mismatch. Verify your SSL and SNI settings.
• 502 Errors: Blog origin not serving SSL properly. Ensure WordPress responds with a valid cert.
• Redirect Loops: Check trailing slashes in proxy_pass and WordPress site URL configuration.

Optimising Your Setup for WordPress subdirectory SEO

URL Structure and Permalinks

WordPress permalinks should reflect keywords:

• /blog/seo-guide-for-shopify
• /blog/nginx-reverse-proxy-tutorial

Short, descriptive URLs are easier to crawl and share.

Metadata and Headers

Use plugins like Yoast or Rank Math to craft unique titles and meta descriptions. Add cache headers in Nginx:

location ~* \.(jpg|css|js)$ {
    expires 30d;
    add_header Cache-Control "public";
}

That speeds up images, styles and scripts—critical for Core Web Vitals.

Performance and Caching

• Browser caching: As above.
• Object caching: On the WordPress host (Redis or Memcached).
• CDN caching: Edge caching on CloudFront or Cloudflare for static assets.

All these tweaks reinforce your subfolder’s SEO strength by improving load times and reducing bounce rates.

Monitoring, Analytics, and Ongoing Maintenance

Once your reverse proxy is live, keep an eye on:

• Google Search Console: Monitor indexing of /blog pages.
• Shopify analytics: Track store referrals from blog posts.
• WordPress logs: Catch 404s or proxy errors.
• Uptime monitoring: Ensure both origins respond correctly.

Regularly review SSL certificate expiry. Let’s Encrypt renewals behind a proxy can fail silently—set alerts to avoid downtime.
