Summary

Launching a new website? Don't let technical issues cripple your growth. Our 50-point technical SEO checklist covers everything from indexing and site speed to mobile-friendliness and schema markup, setting you up for search engine success from day one.

Technical SEO Checklist for New Websites (50-Point Guide)

Launching a new website is a landmark moment, but what happens after you hit 'publish' is what truly defines its success. Without a rock-solid technical foundation, even the most visually stunning site is invisible to search engines. This 50-point technical SEO checklist is your blueprint for ensuring Google, Bing, and other search engines can find, crawl, and rank your content effectively from the very beginning.

Ignoring these fundamentals is costly. A study by OnCrawl found that technical SEO issues can prevent search engines from crawling up to 60% of a large website's pages. For a new site, that means leaving the majority of your potential traffic on the table. Let's build it right.

Phase 1: Foundational Setup & Indexing

This is the bedrock. Getting these initial steps right ensures your website is visible and accessible to search engine crawlers.

Domain & Security

  • Choose a Reputable Host: Your host impacts speed and uptime. Aim for a provider with a guaranteed uptime of 99.9% or higher.
  • Install an SSL Certificate: Ensure your site runs on HTTPS. Google has used this as a ranking signal since 2014. It's a non-negotiable trust factor for users and search engines alike. A secure connection is so vital that we wrote a whole guide on why HTTPS and SSL matter more than ever.

Search Engine Console Setup

  • Set up Google Search Console (GSC): This is your direct line of communication with Google. It provides critical data on crawl errors, indexing status, and keyword performance. If you're new to this, our guide on how to set up Google Search Console for your new website is the perfect starting point.
  • Set up Bing Webmaster Tools: While Google holds over 90% of the search market, Bing still accounts for millions of searches. It's a free and valuable source of data and traffic.
  • Install Google Analytics 4 (GA4): Track user behaviour, conversions, and traffic sources to understand what's working and what isn't.

Crawlability & Indexability

  • Create a `robots.txt` File: This file tells search engines which pages or sections of your site they shouldn't crawl. A misconfigured `robots.txt` can accidentally block your entire site. Draftly automatically generates an optimised file, but it's always good to know where to find it.
  • Generate and Submit an XML Sitemap: Your sitemap is a roadmap of your website for search engines. Submit it via Google Search Console to help Google discover all your important pages faster. With Draftly, this is handled for you, and you can learn more in our guide to the Draftly Sitemap and Robots.txt.
  • Check for Accidental `noindex` Tags: A `noindex` tag tells Google not to include a page in its search results. Ensure these aren't present on pages you want to rank.
  • Establish a Canonical Domain: Decide whether you'll use `www` or `non-www` as your primary domain version and set up 301 redirects for the other version to avoid duplicate content issues.
  • Check `h1` Tags: Every page should have one, and only one, `h1` tag. It's the primary signal of the page's topic.

Phase 2: On-Page Technical Optimisation

These elements live on your pages and help search engines understand your content's context and relevance.

URL Structure

  • Use SEO-Friendly URLs: URLs should be clean, readable, and contain your primary keyword. For example, `yourdomain.com/technical-seo-checklist` is far better than `yourdomain.com/p?id=123`.
  • Keep URLs Short: Shorter URLs (around 50-60 characters) tend to rank better in search results.
  • Use Hyphens for Separation: Use hyphens (`-`) to separate words in URLs, not underscores (`_`) or spaces. Following these URL Structure Best Practices for SEO is a simple win.

Metadata

  • Unique Title Tags: Every page needs a unique title tag that accurately describes its content.
  • Title Tag Length: Keep titles under 60 characters to avoid truncation in search results.
  • Unique Meta Descriptions: While not a direct ranking factor, a compelling meta description (under 160 characters) increases click-through rates by up to 5.8%.
  • Alt Text for Images: Add descriptive alt text to all important images. This helps with accessibility and image search rankings.

Content and Links

  • Logical Heading Structure: Use headings (H1, H2, H3) to structure your content logically. This improves readability for users and helps search engines understand the page hierarchy.
  • Check for Duplicate Content: Use a tool like Siteliner to find and fix any duplicate content issues across your site.
  • Implement Internal Linking: Link relevant pages on your site to each other. This distributes link equity and helps users and crawlers navigate your site.
  • Find and Fix Broken Links: Broken links create a poor user experience and waste crawl budget. Run a broken link check before and after launch.

Phase 3: Site Speed & Performance

Page speed isn't just a technical metric; it's a user experience and conversion metric. A 1-second delay in load time can reduce conversions by 7%.

Core Web Vitals

  • Largest Contentful Paint (LCP): Aim for an LCP of under 2.5 seconds. This measures how long it takes for the main content of a page to load.
  • Interaction to Next Paint (INP): Aim for an INP below 200 milliseconds. This new metric measures overall responsiveness to user interactions.
  • Cumulative Layout Shift (CLS): Aim for a CLS score below 0.1. This measures visual stability, ensuring elements don't jump around as the page loads. Understanding the nuances of Core Web Vitals in 2025 is key to outranking competitors.

Asset Optimisation

  • Compress Images: Use tools like TinyPNG to compress images without sacrificing quality.
  • Use Modern Image Formats: Serve images in next-gen formats like WebP or AVIF, which offer better compression than JPEG or PNG.
  • Lazy Load Offscreen Assets: Defer the loading of images and videos that are not yet in the user's viewport.
  • Minify CSS, JavaScript, and HTML: Remove unnecessary characters from your code to reduce file sizes.

Caching & Server Response

  • Enable Browser Caching: Store parts of your website in a user's browser so it loads faster on subsequent visits.
  • Use a Content Delivery Network (CDN): A CDN stores copies of your site in multiple locations globally, serving it to users from the nearest server.
  • Check Time to First Byte (TTFB): Aim for a TTFB under 200ms. This measures how quickly your server responds to a request.

Phase 4: Mobile-Friendliness

With over 60% of global website traffic coming from mobile devices, a mobile-first approach is mandatory.

  • Ensure Responsive Design: Your website should adapt seamlessly to any screen size, from desktops to smartphones.
  • Use Google's Mobile-Friendly Test: Run your site through this free tool to identify any mobile usability issues.
  • Legible Font Sizes: Use a base font size of at least 16px for body text on mobile.
  • Adequate Tap Target Spacing: Ensure buttons and links are easy to tap without accidentally hitting something else.
  • Avoid Intrusive Interstitials: Google penalizes sites that use aggressive popups that cover the main content on mobile.

Phase 5: Advanced Technical SEO

Once the basics are covered, these advanced elements can give you a competitive edge.

Structured Data (Schema)

  • Implement Organization/LocalBusiness Schema: Tell Google essential information about your business, like your address, phone number, and logo.
  • Use FAQ Schema: Mark up FAQ sections to be eligible for rich results in search.
  • Add Product Schema: For e-commerce sites, this allows Google to display price, availability, and review ratings directly in search results.
  • Validate Your Schema: Use Google's Rich Results Test tool to ensure your structured data is implemented correctly.

Security & Status Codes

  • Set up a Custom 404 Page: Create a helpful 404 page that guides users back to relevant content when they hit a broken link.
  • Audit Redirects: Minimize redirect chains (e.g., Page A -> Page B -> Page C) as they slow down your site and dilute link equity.
  • Use 301 Redirects for Permanent Moves: When a page's URL changes permanently, use a 301 redirect to pass along its SEO value.
  • Monitor for 5xx Server Errors: These indicate a problem with your server and should be fixed immediately.
  • Use `hreflang` for Multilingual Sites: If you target multiple regions or languages, use `hreflang` tags to show Google the correct version of a page.

Phase 6: Post-Launch Monitoring

A technical SEO checklist isn't a one-time task. It's an ongoing process of monitoring and maintenance.

  • Monitor Crawl Errors in GSC: Regularly check the 'Coverage' report for any errors that prevent Google from crawling your pages.
  • Track Core Web Vitals Over Time: Keep an eye on your CWV report in GSC to catch performance regressions.
  • Schedule Regular Link Audits: Run a broken link checker quarterly.
  • Check for Index Bloat: Ensure that low-value pages like internal search results or old tag pages aren't getting indexed and wasting crawl budget.
  • Perform a Full Site Crawl: Use a tool like Screaming Frog or Ahrefs Site Audit to perform a comprehensive technical audit every 3-6 months.
Building a website is just the first step. Building a website that search engines love requires a deliberate, technical approach. While this checklist seems extensive, platforms like Draftly are designed to handle the heavy lifting, from automatic sitemap generation to built-in performance optimization.

Frequently Asked Questions

Why is technical SEO important for a new website?

Technical SEO is crucial for a new website because it ensures search engines can find, crawl, and index your pages efficiently. Without a solid technical foundation, even the best content may never be seen by your target audience, severely limiting your organic traffic potential from day one.

How often should I perform a technical SEO audit?

For a new website, it's wise to run a mini-audit after the first month to catch any launch issues. After that, a comprehensive technical SEO audit every 3-6 months is a good practice. This helps you stay ahead of algorithm changes, fix broken links, and maintain optimal site performance.

Can I do technical SEO myself?

Many basic technical SEO tasks, like submitting a sitemap or checking for broken links, can be done by a website owner. However, more complex issues like schema implementation or fixing crawl errors might require specialized tools or expertise. Platforms like Draftly handle many of these elements automatically.
