How to Check If Your Website Has Been Optimized for Google SEO?

In today’s digital era, a website is more than just a company profile—it’s a powerful sales, marketing, and branding tool on Google.
However, for a website to truly perform and rank high on Google, the key factor is comprehensive SEO optimization.

Many businesses own beautiful websites that cost tens of millions of VND, yet receive little to no organic traffic because their websites are not SEO-compliant.

In this guide, MIMA Digi—Vietnam’s leading SEO website design agency—will share 15 essential criteria to evaluate whether your website meets Google’s SEO standards, helping you audit your site like a professional website doctor.

1️⃣ Check Domain Age – The “Trust Indicator” of Your Website

Domain age is one of the factors Google considers when assessing a website’s credibility.

The older and more reputable your domain, the higher it’s valued.
Conversely, new domains often require time for Google to build trust.

🔧 How to check: Visit whois.com or who.godaddy.com > Enter your domain → Look for “Creation Date.”

🎯 Evaluation How to Check If Your Website Has Been Optimized for Google SEO:

• Over 3 years: Excellent
• 1–3 years: Average
• Under 1 year: New – requires consistent SEO effort

💡 MIMA Digi Expert Tip: When launching a new site, buy a domain with a 5–10 year duration. It signals to Google that your business is long-term and trustworthy.
Also, choose a domain that matches your main keyword—it will perform better than a purely branded domain.

2️⃣ Check Keyword Rankings Using Semalt Extension

A well-optimized SEO website must have keywords ranking on Google—especially in the Top 1–3–10 positions. Semalt SEO Extension (Chrome) allows you to quickly check keyword rankings across key positions.

🔧 Steps: Install Semalt SEO Extension → Open your website → Click the Semalt icon → View “Keywords in TOP 1 / 3 / 10 / 50 / 100.”

🎯 Evaluation How to Check If Your Website Has Been Optimized for Google SEO:

• Over 50 keywords in TOP 10: SEO is performing well.
• Fewer than 10 keywords: Optimize content, backlinks, and speed.

💡 Suggestion: MIMA Digi’s full SEO service helps analyze keyword performance and safely boost rankings—no spam, no risk.

Semalt also gives you a big-picture overview: how well your site is indexed, whether content aligns with target keywords, and how strong your domain truly is.

3️⃣ Check Website History Using Web Archive

If your website changes its source code or design too frequently, Google may reduce its trust.
Web Archive (web.archive.org) lets you review older versions of your site over the years.

🔧 Steps: Go to web.archive.org → Enter your website URL → See historical snapshots.

🎯 Evaluation How to Check If Your Website Has Been Optimized for Google SEO:

• Gradual, reasonable updates → ✅ Good
• Frequent, full code replacements → ⚠️ May hurt SEO (Google needs to “relearn” your site)

💡 Tip: When upgrading your site, keep old URL structures and use 301 redirects to preserve ranking.

Wayback Machine is a great tool for consultants and developers to understand your site’s evolution and plan effective SEO strategies.

4️⃣ Check Programming Language & Website Content

A properly optimized SEO website must use clean, fast, and modern code, with content following Google’s best practices.

🎯 Evaluation How to Check If Your Website Has Been Optimized for Google SEO:

• Good: PHP, HTML5, Next.js, React.js
• Needs optimization: Outdated WordPress plugins, old Laravel versions, or cloned code

You can use Wappalyzer.com to detect which technologies are used on your website.

💡 Quick tip: If you’re using WordPress → Press Ctrl+U (Windows) or Command+Option+U (Mac) → Find “wp-” to confirm. While WordPress is user-friendly, it often causes SEO problems over time (plugin conflicts, CSS errors, slow updates, etc.).

Professional advice: For long-term SEO success, use custom-coded sites rather than template-based WordPress designs.

5️⃣ Check Whether Your Website Is Custom-Coded or Template-Based

Not all websites are coded for SEO. You must know whether your site is:

• Custom-coded (full ownership)
• Template-based or rental site

🎯 Evaluation How to Check If Your Website Has Been Optimized for Google SEO:

• Custom website: Designed from scratch → Fast, secure, scalable, and SEO-ready
• Template or rental site: Often buggy, slow, hard to rank, and limited in customization

💡 Tip: If you’re using a template or rental model, upgrade to a custom SEO website at MIMA Digi for better security, speed, and ranking.

6️⃣ Check URL Structure

A good SEO website has clean, short URLs containing relevant keywords.

✅ Example of good URL: tenmien.com/thiet-ke-website-chuan-seo

❌ Bad examples:

• tenmien.com/index.php (redundant)
• tenmien.com/dich-vu/thiet-ke-website-chuan-seo-39 (auto-generated ID)
• tenmien.com/service/thiet-ke-website-chuan-seo (English path for Vietnamese keyword)

💡 Tip: Use Screaming Frog SEO Tool to scan your entire site’s URL structure.

7️⃣ Check UX/UI Design

Google highly values user experience (UX). Your site must look beautiful, be easy to navigate, and work flawlessly on all devices.

🎯 Checklist:

• Responsive on mobile
• Readable fonts, harmonious colors
• Clear CTAs (buttons)
• No intrusive pop-ups or overlapping banners

💡 Tip: Always design separate, responsive versions for desktop and mobile for the best experience.

8️⃣ Check Sitemap.xml

Sitemaps help Google understand your website structure. Missing or broken sitemaps lead to incomplete indexing.

🔧 Check: Go to yourdomain.com/sitemap.xml

🎯 Goals:

• Sitemap exists and lists all product/news/service URLs
• Submitted in Google Search Console
• Over 500–1000 indexed links → site is performing well

9️⃣ Check the 7 On-Page SEO Factors

• Title: 55–65 characters, include main keyword naturally
• Description: 150–160 characters, summarize article value
• Headings: 1 H1 per page, H2/H3 for subtopics
• Backlinks: 3–5 internal links per article
• Image ALT: Describe image content with keywords
• Content: 2,500–10,000 words, original, structured
• Schema: Use JSON-LD for structured data (Article, LocalBusiness, Rating, etc.)

💡 Tip: Check schema validity at validator.schema.org - content website

10️⃣ Check for Broken Links or Functional Errors

A single broken link (404) can damage SEO. Check for:

• Non-working buttons
• Broken images
• 404 / 301 / 500 errors
• Live chat, maps, forms, and share buttons

🔧 Tool: Use Broken Link Checker extension or Google Search Console.

11️⃣ Check Website Speed

Website speed directly affects Google rankings.

🔧 Tool: PageSpeed Insights

🎯 Evaluation How to Check If Your Website Has Been Optimized for Google SEO:

• 90+ points: Excellent
• 50–90: Average
• Below 50: Needs optimization

💡 MIMA Digi offers speed optimization services to help your site reach 70–90 points.

12️⃣ Check Structured Data (Schema Markup)

Google uses schema for rich snippets (ratings, FAQs, etc.). 🔧 Use validator.schema.org

Ensure you have:

• ⭐ Ratings
• Breadcrumbs
• LocalBusiness info

13️⃣ Use SeoQuake Extension

SeoQuake is a free Chrome extension that checks:

• Canonical links
• Titles & Meta tags
• Headings
• ALT tags
• Internal/External links
• Schema
• Robots.txt, Sitemap.xml
• Analytics integration

✅ Green marks = Good SEO health

❌ Red marks = Need fixing

14️⃣ Integrate Google Search Console

An absolute must for every SEO website.

It allows you to:

• Track performance
• Check indexing errors
• Identify broken links
• Analyze keywords and backlinks
• Review schema and structured data

15️⃣ Check Hosting Quality

Hosting is the foundation of your website. Weak hosting → Slow site → Poor SEO.

Make sure your server meets SEO-level specs for:

• Bandwidth
• RAM/CPU
• Database (MySQL)
• Backup
• Scalability

💡 MIMA Digi uses high-performance, SEO-optimized hosting for fast, stable websites 24/7.
