How to Check If Your Website Is SEO Friendly

May 5, 2026·8 min read

"Is my website SEO friendly?" — it is one of the most common questions website owners ask. The answer determines whether Google can find, understand, and rank your pages. An SEO-friendly website follows best practices that make it easy for search engines to crawl, index, and display your content in search results. Here is a 10-step checklist to find out.

💡 Quick Check

Want an instant answer? Run a free SERPlyft audit — it checks all 10 factors below (and 40+ more) in 30 seconds.

1. Title Tags Are Optimized

✓Good: Unique, 50-60 characters, includes primary keyword near the beginning

✗Bad: Missing, generic ('Home'), over 60 characters, or duplicate across pages

How to check: View your page source (Ctrl+U) and look for the <title> tag. Or use SERPlyft's free audit — it checks this automatically.

2. Meta Descriptions Are Compelling

✓Good: 150-160 characters, includes keyword, has a call-to-action

✗Bad: Missing, over 160 characters (gets truncated), or same on every page

How to check: Check the <meta name='description'> tag in your page source. Google may rewrite it, but having a good one improves CTR.

3. Your Site Uses HTTPS

✓Good: URL starts with https:// and shows a lock icon

✗Bad: URL starts with http:// or shows 'Not Secure' warning

How to check: Look at your browser's address bar. If you see a lock icon, you have HTTPS. If not, get a free SSL certificate from Let's Encrypt.

4. Mobile-Friendly Design

✓Good: Content adapts to all screen sizes, buttons are tappable, no horizontal scrolling

✗Bad: Desktop-only layout, tiny text on mobile, overlapping elements

How to check: Open your site on your phone. Can you read everything? Can you tap all buttons easily? Also test with Google's Mobile-Friendly Test.

5. Page Loads Fast

✓Good: Under 3 seconds on mobile, LCP under 2.5 seconds

✗Bad: Takes more than 5 seconds, large uncompressed images, too much JavaScript

How to check: Test your URL on Google PageSpeed Insights. Aim for a score of 90+ on mobile.

6. Proper Heading Structure

✓Good: One H1 per page, logical H2/H3 hierarchy, headings describe content

✗Bad: Multiple H1s, skipping levels (H1 → H4), headings used just for styling

How to check: Right-click → View Source and search for <h1>, <h2>, <h3> tags. Each page should have exactly one H1.

7. Images Have Alt Text

✓Good: Descriptive alt text on every image, includes relevant keywords naturally

✗Bad: Empty alt attributes, generic alt like 'image1.jpg', no alt at all

How to check: Right-click any image → Inspect Element. Look for the alt attribute. It should describe what the image shows.

8. Internal Links Connect Your Content

✓Good: Important pages linked from the homepage, blog posts link to related guides

✗Bad: Orphan pages (no links pointing to them), navigation-only linking

How to check: Check if your key pages are reachable within 3 clicks from the homepage. Use descriptive anchor text, not 'click here'.

9. XML Sitemap Exists

✓Good: Available at /sitemap.xml, lists all important pages, submitted to Google Search Console

✗Bad: No sitemap, includes noindex pages, or outdated

How to check: Visit yoursite.com/sitemap.xml. If you get a 404, you need to create one. Most CMS platforms generate them automatically.

10. Structured Data Is Present

✓Good: JSON-LD schema for your content type (Article, Product, LocalBusiness, FAQ)

✗Bad: No structured data at all — you're missing out on rich snippets in Google

How to check: Test your URL with Google's Rich Results Test tool. If no structured data is found, add JSON-LD schema to your pages.

What to Do After Your Check

If your website passes all 10 checks above, congratulations — your site has a solid SEO foundation. Focus on creating high-quality content and building backlinks.

If you failed some checks, do not panic. Most SEO issues are straightforward to fix. Start with the highest-impact items: title tags, HTTPS, and page speed. These three alone can significantly improve your search visibility.
