SEO Analysis: How to Audit Your Website Step by Step

What Is an SEO Analysis?

An SEO analysis, often called an SEO audit, is a systematic check of how well your website performs in search engines. The analysis covers four main areas: technology, content, links, and user experience.

The goal is simple. You need to find the errors that cost you visibility, and the opportunities your competitors haven't spotted. Are you completely new to the topic? Then start by reading about what SEO is or take a look at our guide for SEO beginners.

In 2026, the analysis is about more than Google. Services like ChatGPT, Gemini, and Google's own AI answers pull information from websites and give the user the answer directly. A modern SEO analysis therefore also checks how visible you are in these answers. More on that in step 7.

Step 1: Check Technical SEO

Technology is the foundation. If the site has technical errors, good content won't help. This step takes about an hour with free tools.

Crawling and Indexing

Google must be able to read your pages and store them in its index. This is called crawling and indexing. Google Search Console shows which pages Google has indexed, and which ones have issues. A tool like Screaming Frog finds broken links, blocked pages, and missing titles.

Check these points:

• Are the important pages indexed? See the "Pages" report in Search Console.
• Is robots.txt blocking anything it shouldn't?
• Do you have an updated XML sitemap?
• Are there broken links on the site?

Want a quick technical review? SEO-Analyse.no, our free SEO checker, runs more than 30 tests on your website. The tool was developed by us at Mementor. If you are rebuilding from scratch, it is worth reading what makes an SEO-friendly website.

Core Web Vitals

Core Web Vitals are Google's measure of user experience, and they count toward ranking. Three values apply in 2026:

• LCP (Largest Contentful Paint) measures how quickly the main content appears. A good value is under 2.5 seconds.
• INP (Interaction to Next Paint) measures how quickly the page responds when the user clicks or types. A good value is under 200 milliseconds. INP replaced the old FID metric in March 2024.
• CLS (Cumulative Layout Shift) measures whether the content jumps around while the page loads. A good value is under 0.1.

Measure the values with PageSpeed Insights or GTmetrix. Search Console also has a dedicated Core Web Vitals report with real user data.

Security and HTTPS

The entire website should run on HTTPS. This protects users and is a ranking signal for Google. Check that the SSL certificate is valid, and that old http addresses redirect to https.

Step 2: On-Page SEO Analysis of Your Content

This step takes one to two hours, depending on how many pages you review. Start with the pages that matter most for sales.

Titles and Meta Descriptions

The title is the first thing people see in the search result. It should include the keyword and be under about 60 characters. The meta description should be around 150 characters and give people a reason to click.

Example of a good title: "SEO Services for Small Businesses." It's short and clear, and the keyword comes early.

Example of a good meta description: "Want more customers from Google? We help small businesses rank higher. Request a free assessment today." It explains the value and tells the reader what to do.

Headings

Use one H1 per page. Divide the rest of the content with H2s and H3s. This helps both readers and search engines understand the structure. Write headings that answer what people are actually searching for.

Keywords in the Text

Use the keyword naturally in the title, in the first paragraph, and in some headings. Forget old rules about keyword density in percentages. Google has no ideal density, and too many repetitions can do more harm than good. Instead, use words that naturally belong to the topic. If you're writing about SEO analysis, words like indexing, keywords, and ranking belong with it. Want to get better at this? Read our SEO writing guide.

Step 3: Assess the User Experience

This step takes about 30 minutes with free tools.

Mobile First

Google uses the mobile version of your website when ranking you. This is called mobile-first indexing. The site must therefore work just as well on mobile as on a PC.

Google's old mobile-friendly test was discontinued in December 2023 and no longer exists. Instead, use PageSpeed Insights or Lighthouse in your browser. There you can see how the page performs on mobile. A mobile-friendly web design leads to longer visits and more inquiries.

Speed

Slow pages lose visitors. Many people leave the page before it finishes loading. Common culprits are large images, heavy scripts, and slow servers. PageSpeed Insights tells you what's slowing down your page. Fast WordPress hosting close to your visitors also cuts loading time.

Structure and Navigation

Important pages should be a maximum of three clicks from the homepage. A logical menu and good internal links help both users and search engines. Check that each important page has at least one internal link pointing to it.

Step 4: Analyze Your Links

This step takes 30 to 60 minutes with a link tool like Ahrefs or Semrush.

External Links (backlinks)

Links from other websites act as recommendations. Quality beats quantity. One link from a well-known industry site is worth more than a hundred links from weak sites.

Tools like Ahrefs and Semrush show who links to you. Ahrefs uses the Domain Rating (DR) metric, and Semrush uses Authority Score. Both give an indication of how strong your links are.

Anchor Texts

The anchor text is the clickable text in a link. It should describe the page the link points to. Vary the texts. If all links use exactly the same keyword, it can look manipulated to Google.

Competitors' Links

Check where your competitors get their links from. Use Ahrefs or Semrush to see their link profile. You'll often find directories, blogs, and media outlets that could link to you too. Working toward a local market? Then local SEO often provides the easiest links, for example from local directories and newspapers.

Step 5: Do a Keyword Analysis

This step takes one to two hours the first time. It goes faster once you know your keywords.

Find the Right Keywords

You need to know what your customers are actually typing into the search field. Google's Keyword Planner shows search volume and competition for free. Ahrefs and Semrush provide deeper numbers and show your competitors' keywords.

Look especially for long and specific searches. "SEO analysis of an online store" has fewer searches than "SEO," but those searching that way are much closer to a decision. You find the full walkthrough of the keyword research process in our dedicated guide.

Avoid Pages Competing with Each Other

If you have several pages on the same topic, they can compete for the same keyword. This is called cannibalization. Then Google doesn't know which page to show, and all the pages lose out. The solution is to merge the pages or give each one a distinct topic. Give each important keyword one dedicated page.

Step 6: Analyze the Competitors

This step takes about an hour for your three closest competitors. Search for your most important keywords, and see who ranks at the top. Then analyze their pages. What do they write about? How thorough is the content? Where do they get links from?

A gap analysis shows topics competitors cover that you're missing. Ahrefs and Semrush have dedicated features for this. Once you've listed the gaps, you have your content plan for the coming months. Need concrete ideas for action? You'll find more in our 15 SEO tips.

Step 7: Check Your Visibility in AI Search

This step was missing from older SEO analyses. In 2026, it has become an important part. It takes about 30 minutes of manual testing.

Google shows AI-generated answers at the top of many searches. An analysis from Conductor in early 2026 found such answers in roughly one in four searches. Pew Research has also measured that fewer people click on regular results when an AI answer is shown. In addition, more and more people ask ChatGPT, Gemini, and Perplexity directly instead of googling.

The work of becoming visible in these answers is called AEO, Answer Engine Optimization. Include these points in the analysis:

• Is your business mentioned when you ask ChatGPT or Gemini for recommendations in your industry?
• Is your website used as a source in Google's AI answers?
• Do your pages clearly answer specific questions, preferably early in the text?
• Do you have structured data in place, such as FAQ and article markup?

The Best SEO Analysis Tools

Free tools from Google cover most of an SEO audit: Search Console shows how Google reads your website, and PageSpeed Insights measures speed. Paid software like Ahrefs, Semrush and Moz Pro adds depth on backlinks, keywords and competitors. Start free, and pay only when you need deeper data.

The table shows the SEO analysis tools we use most, and what each one is best at:

Measure Your SEO Performance: Reporting and Follow-Up

An SEO analysis without follow-up is wasted effort. Set fixed goals, and track progress month by month.

Use Google Search Console to track clicks, impressions, and positions. Google Analytics 4 shows what visitors do after they click. Ahrefs or Semrush tracks your rankings over time. To check your SEO ranking on a specific search, open the Performance report and filter by query. It shows your exact average position.

Our customers get their own SEO dashboard that gathers all SEO analytics in one place, with daily updated figures. The dashboard shows rankings in Google, visibility in AI answers, and local positions per city. That way you see the effect of every measure, in black and white. The numbers are what make the work visible: after we rebuilt the website for Stas Artist, new users from organic search grew 199 percent in the first seven months. Read more about our SEO services.
