Checklist for Technical SEO in 2025

Content (Formatted for CMS Editor)

Introduction
You could have the best content on the internet—but if your technical SEO isn’t right, Google may never show it. Technical SEO focuses on making your website crawlable, indexable, secure, fast, and mobile-friendly.

This 2025-ready checklist by BoomXMedia covers all the technical essentials to help your website rank higher and perform better.


1. Mobile Optimization
More than 60% of web traffic comes from mobile devices, and Google now uses mobile-first indexing. This means it crawls and indexes the mobile version of your site first.

Make sure:

  • Your website has a responsive design

  • Text and buttons are readable and tappable

  • Navigation is clear and simple

  • Popups don’t interfere with usability

Use Google’s Mobile-Friendly Test to check your site.
Tip: Don’t just test on one device—use multiple screen sizes.


2. Site Speed and Core Web Vitals
Speed is a ranking factor and a major UX signal. If your site takes longer than 3 seconds to load, users leave—and so does your SEO performance.

Focus on improving these Core Web Vitals:

  • Largest Contentful Paint (LCP): Should load within 2.5 seconds

  • First Input Delay (FID): Should be under 100 ms

  • Cumulative Layout Shift (CLS): Keep it below 0.1

Tools to test:

  • Google PageSpeed Insights

  • Lighthouse

  • GTmetrix

Optimization Tips:

  • Compress and lazy-load images

  • Use a fast, secure hosting server

  • Minify and combine CSS/JS files

  • Enable browser caching and CDN support


3. XML Sitemap and Robots.txt
An XML Sitemap helps search engines understand the structure of your site and index it efficiently.

Steps:

  • Create a dynamic sitemap using your CMS or plugin

  • Submit it in Google Search Console

  • Update your sitemap when new pages are added

Your robots.txt file tells search bots what to crawl and what to skip.

Make sure:

  • Important pages aren’t accidentally blocked

  • Pages like checkout, login, and admin are correctly disallowed

One wrong directive in robots.txt can de-index key pages—check it often.


4. Structured Data and Schema
Schema markup helps search engines understand your content better, which can lead to rich snippets (stars, images, pricing, FAQs) in SERPs.

Use schema types such as:

  • Article (for blog posts)

  • Product (for eCommerce)

  • Review (for testimonials)

  • FAQ (for Q&A sections)

  • Local Business (for service area companies)

Tools to use:

  • Google’s Structured Data Markup Helper

  • Rich Results Test

Implementing the right schema boosts CTR, visibility, and SEO trust.
