How to Check Your Website SEO Score Using OpDeck's Audit Tool

If you want to check your website's SEO score, you've come to the right place. Whether you're launching a new site, troubleshooting a traffic drop, or simply doing routine maintenance, understanding your SEO score gives you a clear picture of how well your site is optimized for search engines — and where you're losing ground. This guide walks you through exactly how to do it, what the numbers mean, and what actions to take based on what you find.

What Is an SEO Score and Why Does It Matter?

Before diving into the how, it helps to understand what an SEO score actually represents. An SEO score is a composite metric that reflects how well your website follows SEO best practices across several categories: on-page content, technical structure, meta data, heading hierarchy, and more.

It's not a number Google officially publishes — no such thing exists. Instead, SEO audit tools analyze your page against a set of known ranking factors and best practices, then assign a score (usually out of 100) that tells you how well-optimized your site is.

A high score doesn't guarantee top rankings, but a low score almost always explains poor performance. Think of it as a health check: a score of 40 means your site has significant issues that are likely holding it back. A score of 85 or above means you're in solid shape, though there's always room to improve.

What Factors Influence Your SEO Score?

Different tools weigh different things, but most comprehensive audits look at:

Title tags — Are they present, the right length, and do they include target keywords?
Meta descriptions — Are they compelling, within character limits, and unique per page?
Heading structure — Is there a single H1? Are H2s and H3s used logically?
Content quality — Is there enough text? Are keywords used naturally?
Image alt attributes — Are images described for both accessibility and search engines?
Canonical tags — Is duplicate content handled properly?
Internal and external links — Are links working and pointing to relevant pages?
Page load speed — Does the page load fast enough to satisfy users and crawlers?
Mobile friendliness — Is the page usable on small screens?
Structured data — Is schema markup present to help search engines understand content?

Each of these factors contributes to your overall score, and fixing them in order of impact is how you systematically improve your SEO.

How to Check Your Website's SEO Score with OpDeck

The fastest way to check your website's SEO score is to use OpDeck's SEO Audit tool. It's a free, no-login-required tool that gives you an instant breakdown of your page's SEO health — no complicated setup, no waiting for a crawl to finish.

Here's how to use it step by step.

Step 1: Navigate to the SEO Audit Tool

Go to https://www.opdeck.co/tools/seo-audit. You'll see a simple input field where you can enter any URL — your homepage, a landing page, a blog post, or any page you want to evaluate.

Step 2: Enter Your URL

Type or paste the full URL of the page you want to audit. Make sure you're entering the exact URL as it appears in the browser, including https://. If you want to check your homepage, enter https://yourdomain.com. If you're auditing a specific blog post, enter that full URL.

Pro tip: Don't just check your homepage. Your blog posts, product pages, and service pages often have the most SEO potential and the most overlooked issues. Run audits on your highest-traffic pages first.

Step 3: Run the Audit

Click the audit button and wait a few seconds while OpDeck fetches and analyzes the page. The tool examines your page's actual rendered HTML — the same content search engine crawlers see — so the results reflect real-world conditions.

Step 4: Review Your SEO Score

Once the audit completes, you'll see an overall SEO score along with a detailed breakdown of individual checks. Each item is flagged as passed, needs improvement, or failed, so you know exactly what to fix.

Understanding Your SEO Audit Results

Getting a number is only half the job. Understanding what it means — and what to do about it — is where the real work begins.

Title Tag Analysis

Your title tag is one of the most important on-page SEO elements. OpDeck checks:

Presence — Does a title tag exist?
Length — Is it between 50 and 60 characters? Titles shorter than 30 characters are too vague; longer than 65 characters get truncated in search results.
Keyword inclusion — Does it contain a relevant keyword?

What to do if it fails: Open your CMS or HTML and update the <title> tag. For WordPress users, a plugin like Yoast SEO or Rank Math makes this easy. For custom sites, you're editing the <head> section directly:

<head>
  <title>How to Bake Sourdough Bread at Home | YourBrand</title>
</head>

Keep it descriptive, front-load the keyword, and keep it under 60 characters.

Meta Description Check

The meta description doesn't directly affect rankings, but it heavily influences click-through rates — which do affect your traffic and, indirectly, your rankings. OpDeck checks:

Presence — Is a meta description defined?
Length — Optimal range is 150–160 characters.
Uniqueness — Is it specific to this page, or is it a generic site-wide description?

Fix it like this:

<meta name="description" content="Learn how to bake sourdough bread at home with this step-by-step guide. Includes starter tips, hydration ratios, and baking schedules for beginners." />

Write it like ad copy — it should make someone want to click.

Heading Structure (H1, H2, H3)

Headings help both users and crawlers understand your content structure. The audit checks:

Single H1 rule — There should be exactly one H1 per page, and it should contain your primary keyword.
Logical hierarchy — H2s should be major sections; H3s should be subsections of H2s. Skipping levels (e.g., going from H1 to H4) confuses crawlers.
Keyword presence — Are relevant terms naturally included in subheadings?

Common mistake: Many sites either have no H1 at all, or they have multiple H1s because a theme or template applied the H1 style to decorative text. Check your page source with Ctrl+U (or Cmd+U on Mac) and search for <h1> to see what's actually tagged.

Image Alt Text

Every image on your page should have a descriptive alt attribute. This serves two purposes: it helps screen readers describe the image to visually impaired users, and it gives search engines context about the image content.

<!-- Bad -->
<img src="bread.jpg" alt="image1" />

<!-- Good -->
<img src="sourdough-bread.jpg" alt="Freshly baked sourdough bread on a wooden cutting board" />

OpDeck flags images with missing or empty alt attributes so you can fix them one by one.

Canonical Tags

A canonical tag tells search engines which version of a URL is the "official" one. This matters when you have duplicate content — for example, https://example.com/page and https://example.com/page?ref=newsletter pointing to the same content.

<link rel="canonical" href="https://example.com/page" />

If OpDeck flags a missing or incorrect canonical tag, add it to your page's <head>. Most CMS platforms handle this automatically if configured correctly.

Content Length and Keyword Usage

Thin content — pages with very little text — tends to rank poorly. The audit evaluates whether your page has enough content to be considered authoritative on its topic. While there's no magic word count, most well-ranking pages on competitive topics have at least 800–1,500 words of substantive content.

The audit also checks whether your primary keyword appears in the body text naturally and at an appropriate density. Keyword stuffing (repeating a phrase unnaturally many times) is penalized; too little usage means you're not signaling relevance.

Beyond the SEO Score: Related Checks That Matter

Your SEO score is a great starting point, but it doesn't capture everything that affects your rankings. Here are a few additional areas to investigate alongside your SEO audit.

Page Speed

A slow page hurts your SEO. Google uses Core Web Vitals as a ranking signal, which means load time, visual stability, and interactivity all matter. While OpDeck's SEO Audit tool focuses on on-page factors, you should also run a performance audit using the Website Performance Analyzer to get your Lighthouse scores and identify specific speed bottlenecks.

Mobile Friendliness

Google uses mobile-first indexing, meaning it primarily uses the mobile version of your site for ranking. If your site isn't mobile-friendly, your SEO score improvements won't translate into the rankings you're hoping for. Check your mobile experience separately using the Mobile Insights tool.

Structured Data

Adding schema markup (JSON-LD) to your pages helps search engines understand your content and can unlock rich results — star ratings, FAQ dropdowns, recipe cards, and more in search results. These enhanced listings improve click-through rates significantly. Use the JSON-LD Structured Data Generator to create the right markup for your content type.

SSL Certificate

A valid SSL certificate (HTTPS) is a confirmed Google ranking factor. An expired or misconfigured SSL certificate will hurt your rankings and trigger browser security warnings that drive users away. Verify your certificate status with the SSL Certificate Checker.

How to Prioritize SEO Fixes After Your Audit

Running the audit is easy. Knowing what to fix first is where most people get stuck. Here's a practical prioritization framework:

Fix Critical Failures First

Any item the audit marks as a hard failure — missing title tag, no H1, broken canonical, missing meta description — should be addressed immediately. These are foundational issues that have a direct, measurable impact on how search engines index and rank your pages.

Then Address "Needs Improvement" Items

These are issues that aren't broken but aren't optimal. Short title tags, thin content, images with generic alt text — these all drag your score down and limit your potential. Work through them systematically, page by page.

Create a Spreadsheet to Track Progress

If you're auditing multiple pages (which you should be), create a simple spreadsheet with columns for:

Page URL
SEO Score (current)
Issues found
Priority level
Status (not started / in progress / fixed)
SEO Score (after fix)

Re-run the audit after making changes to confirm the fix registered correctly and your score improved.

Audit on a Regular Schedule

SEO isn't a one-time task. Content changes, plugins update, templates get modified — any of these can introduce new issues. Build a habit of running a full audit on your key pages at least once a month, and always run one after major site updates.

Common Mistakes People Make When Checking Their SEO Score

Only Checking the Homepage

Your homepage is rarely your most important page from an SEO perspective. Product pages, service pages, and blog posts are where most of your organic traffic lands. Make sure you're auditing those pages too.

Treating the Score as a Ranking Guarantee

A score of 90 doesn't mean you'll rank #1. It means you've done the on-page work well. Off-page factors like backlinks, domain authority, and user engagement also matter enormously. Think of your SEO score as the foundation — necessary, but not sufficient on its own.

Ignoring the Audit After One Run

Running the audit once and forgetting about it is a common mistake. SEO is ongoing. New pages get added, old ones get updated, and technical issues creep in over time. Schedule regular audits as part of your standard site maintenance.

Fixing Symptoms Instead of Root Causes

If every page on your site is missing a meta description, the fix isn't to manually add one to every page — it's to find out why your CMS isn't generating them and fix the template. Think systemically, not just page by page.
