Case Study: Malware removal from a Hacked WordPress Website
Complete Malware Removal, and Reindexing in Google of a Local Business Website in West London
In 2017, a local business with multiple outlets across West London, including Kensington, Acton, and Ladbroke Grove, approached us with a critical issue. Their WordPress website had been compromised by a recurring malware injection which was damaging their online presence, brand credibility, and search engine rankings. While the business already had some early visibility in local search results for these areas, the site’s security problems made it impossible to build on that momentum.
Key findings
The problems were severe and multi-layered:
- Daily Spam Injections – The site was auto-publishing irrelevant blog posts in Chinese, Hindi, and English, many of which contained external links to unrelated websites.
- 8,000+ Spam Pages Indexed – Google had crawled and indexed thousands of these injected pages, undermining the business’s domain authority.
- Slow Loading Speeds – The website was taking over 10 seconds to load, leading to poor user experience and low engagement.
- Failed Security Fixes – The site owner had tried resetting WordPress and database passwords several times, but the injections kept returning.
- Local SEO at Risk – The client had some early presence in searches across Kensington, Acton, and Ladbroke Grove, but the compromised site prevented them from capturing valuable local traffic.
20 Best Practices for Headless SEO
Headless SEO Best Practices - What it means and why it Matters?
Below are the 20 essential SEO best practices every developer and marketer should follow when working with a Headless CMS. These include the 12 recognised fundamentals seen in Google’s AI search results — plus 8 advanced methods used by top agencies.
1. Use Schema Markup:
Integrate JSON-LD schema for products, articles, services, and local businesses. Helps Google understand and display your content more effectively.
2. Canonical URLs:
Prevent duplicate content by defining canonical tags for API-driven pages and query parameters.
3. XML Sitemaps
Dynamically generate XML sitemaps for all published API content to guide crawlers efficiently.
4. Create Content Regularly:
Consistent publishing signals freshness and improves ranking momentum, even in headless setups.
5. Ensure Editable URL Slugs:
Let editors customise URL structures directly in the backend — readable slugs boost CTR and keyword value.
6. Keyword Research:
Base your titles, headings, and structured data on researched primary and LSI keywords.
7. Search-Friendly URLs:
Keep URLs clean, lowercase, and hyphenated — for example, /headless-seo-guide/.
8. Structured Heading Hierarchy:
Use logical <h1> to <h3> sequences to help search engines interpret page context.
9. Meta Description:
Automate unique meta descriptions in your API output to improve SERP click-through rates.
10. Use a CDN:
Deliver content through a Content Delivery Network for faster load times globally.
11. Use HTTPS:
Always secure your site with HTTPS — it’s both a ranking and trust signal.
12. Voice SEO:
Optimise for question-based and conversational keywords, supporting FAQ schema for voice assistants.
13. Optimise Core Web Vitals:
Focus on Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and First Input Delay (FID).
14. Dynamic Rendering:
Use server-side rendering (SSR) or pre-rendering to ensure search crawlers see complete HTML, not raw JavaScript.
15. Breadcrumb and Navigation Schema:
Add structured navigation data to improve sitelink visibility and crawl depth.
16. Content API Optimisation:
Make sure APIs expose SEO fields like titles, descriptions, canonical links, and schema data.
17. Local SEO for Headless Sites:
Create location-specific pages and structured LocalBusiness schema for better local visibility.
18. Internal Linking Via API:
Automate internal links in your frontend logic using API references — boosts crawl flow and link equity.
19.Lazy Loading and Image Compression:
Optimise visuals to maintain site speed and accessibility scores.
20. Analytics and Tracking Tags:
Add GA4 or GTM through server-side integrations or SSR scripts for accurate data tracking.
