Most developers treat SEO as a marketing afterthought, deploying code that works perfectly in the browser but fails silently in search engines. A new checklist from DEV.to author Bhavesh P. Tech argues that technical SEO is actually just good engineering hygiene. The guide outlines seven free, actionable checks that catch indexing blockers, broken links, and performance bottlenecks before they impact organic traffic.

Indexing and Crawlability Basics

The foundation of technical SEO is ensuring search engines can actually see your pages. The checklist emphasizes verifying that important pages return successful HTTP responses and do not contain accidental directives inherited from staging environments. Developers must also validate robots.txt files to ensure critical paths aren't blocked and that the sitemap URL is correctly referenced. Remember, allowing crawling does not guarantee indexing; Google still evaluates page suitability, so canonical tags must point to the preferred URL to avoid duplicate content penalties.

Metadata and Structured Data Precision

Generic CMS defaults often result in duplicate titles across pages, confusing both users and crawlers. The guide recommends replacing default tags like Home | Example with descriptive, unique titles such as API Authentication Guide | Example. Beyond titles, structured data using Schema.org types (like Article, Product, or BreadcrumbList) provides context that can trigger rich results. Developers should use Google's Rich Results Test to validate JSON-LD scripts, ensuring the structured data matches the visible page content exactly.

Performance and Link Integrity

Core Web Vitals remain a critical metric for user experience and search evaluation. The checklist targets specific thresholds: Largest Contentful Paint (LCP) under 2.5 seconds, Interaction to Next Paint (INP) under 200 milliseconds, and Cumulative Layout Shift (CLS) below 0.1. These metrics apply at the 75th percentile of visits. Simultaneously, developers must crawl for broken internal links and redirect chains. A link to /old-guide/ that redirects to /guide-v2/ and then /guide/ adds unnecessary latency; update the source link to point directly to the final destination.

Key Takeaways

  • Automate the basics: Integrate robots.txt validation and sitemap checks into your CI/CD pipeline, not just manual pre-launch reviews.
  • Validate, don't guess: Use Google Search Console's URL Inspection tool and Schema.org validator to confirm indexing status and structured data accuracy.
  • Fix redirects at the source: Eliminate redirect chains by updating internal links to point directly to final URLs, reducing crawl budget waste.
  • Monitor post-launch: Submit sitemaps immediately and track organic performance; technical SEO is a maintenance task, not a one-time setup.

The Bottom Line

SEO isn't magic; it's infrastructure. If you can write a unit test for a function, you can script a check for a canonical tag. Stop blaming the algorithm for your missing robots.txt or slow LCP scores.
