How to Do a Website SEO Analysis (Step-by-Step for Beginners)

An SEO analysis is the process of evaluating how well a website is optimized for search engines. Whether you're checking your own site or a client's, here's the exact process professionals follow.

Step 1: Check Technical Foundations

Before anything else, make sure the basics work: the site loads over HTTPS, has a valid sitemap.xml, has a robots.txt file, and responds with proper status codes (200, not 404 or 500).

Step 2: Evaluate On-Page SEO

Check every page for: unique title tag (under 60 chars), meta description (under 155 chars), one H1 tag, proper heading hierarchy (H2, H3), image alt text, and internal links.

Step 3: Test Page Speed

Run the site through Google PageSpeed Insights. Check both mobile and desktop. Focus on Core Web Vitals: LCP, INP, and CLS. Anything in orange or red needs attention.

Step 4: Mobile-Friendliness

Google uses mobile-first indexing — they rank you based on your mobile version. Test on real phones, not just browser resize. Check tap target sizes, font readability, and viewport configuration.

Step 5: Content Analysis

Is the content thin (under 300 words)? Is it duplicate? Does it target specific keywords? Are there content gaps your competitors cover but you don't?

Step 6: Backlink Profile

Check how many sites link to you, the quality of those links, and anchor text distribution. Tools like Ahrefs, Moz, or GetSEOAnalyzer can help.

Step 7: Create an Action Plan

Prioritize fixes by impact: critical technical issues first, then on-page optimization, then content and backlinks.
