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

If you want to check your website's SEO score, you're already thinking about the right things — visibility, rankings, and making sure search engines can actually understand and index your content. An SEO score gives you a snapshot of how well-optimized your site is across a range of technical and on-page factors. In this guide, you'll learn exactly how to check your website's SEO score, what the results mean, and how to act on them to improve your search rankings.

What Is an SEO Score and Why Does It Matter?

An SEO score is a numerical representation of how well your website follows SEO best practices. It typically measures factors like:

Meta tags — whether your title tags and meta descriptions are present, properly formatted, and within recommended character limits
Heading structure — proper use of H1, H2, and H3 tags to organize content
Content quality signals — keyword usage, readability, and content length
Technical elements — canonical tags, robots directives, and structured data
Image optimization — alt text presence and descriptive filenames
Internal and external linking — anchor text quality and link structure

A low SEO score doesn't necessarily mean your site is broken — it means there are specific, fixable issues that could be preventing you from ranking as well as you should. Think of it as a health check for your content and technical setup.

The reason this matters practically: search engines like Google use hundreds of signals to decide where your page ranks. Many of those signals are things you can directly control. An SEO audit surfaces exactly which controllable factors you're missing.

How to Check Your Website's SEO Score with OpDeck

The fastest way to check your website's SEO score is to use the SEO Audit tool on OpDeck. It's a free, browser-based tool that analyzes your page against a comprehensive set of SEO criteria and returns a scored report in seconds.

Here's how to use it step by step:

Step 1: Open the SEO Audit Tool

Navigate to https://www.opdeck.co/tools/seo-audit. No account or login is required.

Step 2: Enter Your URL

Type or paste the full URL of the page you want to audit. This can be your homepage, a blog post, a product page, or any other URL you want to evaluate. Make sure you include the protocol — for example:

https://www.yourwebsite.com/your-page

It's worth auditing individual pages rather than just your homepage, because SEO optimization is page-level work. Your homepage might score well while a critical product page has missing meta descriptions or duplicate title tags.

Step 3: Run the Audit

Click the audit button and wait a few seconds while the tool fetches and analyzes your page. It crawls the live version of your URL, so what you see in the report reflects what search engines actually see when they visit your page.

Step 4: Read the Results

The report breaks down your SEO score into categories. You'll see individual checks with pass/fail indicators and specific details about what was found. Here's what each major section covers:

Understanding the SEO Audit Report

Title Tag Analysis

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

Presence — does a title tag exist at all?
Length — is it within the recommended 50–60 character range?
Uniqueness — is it descriptive and specific to this page?

A title tag that's too long gets truncated in search results. Too short, and you're leaving ranking opportunity on the table. The audit will flag both problems.

Example of a well-optimized title tag:

<title>Best Running Shoes for Flat Feet | ShoeStore</title>

Example of a problematic title tag:

<title>Home</title>

The second example tells search engines and users almost nothing about the page content.

Meta Description Review

Meta descriptions don't directly affect rankings, but they influence click-through rates from search results. The audit checks whether your meta description:

Exists
Falls within the 150–160 character sweet spot
Isn't duplicated from another page on your site

If your meta description is missing, search engines will auto-generate one by pulling random text from your page — which is rarely the most compelling summary of your content.

Example meta description:

<meta name="description" content="Discover the best running shoes for flat feet in 2024. Expert picks, comfort ratings, and buying guide from certified podiatrists.">

Heading Structure

Search engines use headings to understand the hierarchy and topics of your content. The audit evaluates:

Whether an H1 exists (there should be exactly one per page)
Whether H2 and H3 tags are used to organize sub-sections
Whether headings contain relevant keywords

A common mistake is using multiple H1 tags on a single page, which dilutes the signal you're sending to search engines about what the page is primarily about.

Correct heading structure:

H1: How to Train for Your First Marathon
  H2: Building Your Weekly Mileage
    H3: Week 1–4 Training Plan
    H3: Week 5–8 Training Plan
  H2: Nutrition for Long-Distance Runners
    H3: Pre-Run Meals
    H3: Post-Run Recovery Foods

Image Alt Text

Every image on your page should have descriptive alt text. The audit identifies images that are missing alt attributes entirely, as well as images with generic alt text like "image1.jpg" or "photo."

Alt text serves two purposes: it helps screen readers describe images to visually impaired users, and it gives search engines context about what the image shows. Images can rank in Google Image Search, which is additional traffic potential you're leaving unused if alt text is absent.

Bad alt text:

<img src="shoe.jpg" alt="image">

Good alt text:

<img src="running-shoe-flat-feet.jpg" alt="Brooks Adrenaline GTS running shoe for flat feet">

Canonical Tags

A canonical tag tells search engines which version of a URL is the "official" one. This matters when the same content is accessible at multiple URLs — for example, with and without trailing slashes, or with UTM parameters.

The audit checks whether a canonical tag is present and whether it points to the correct URL.

<link rel="canonical" href="https://www.yourwebsite.com/running-shoes-flat-feet/">

Without a canonical tag on pages with URL variations, you risk splitting your ranking signals across multiple versions of the same page.

Robots Meta Tag

The robots meta tag controls whether search engines can index a page and follow its links. The audit flags any pages with restrictive directives that might be accidentally blocking indexing.

<!-- This page will be indexed and links followed -->
<meta name="robots" content="index, follow">

<!-- This accidentally blocks indexing — the audit will flag it -->
<meta name="robots" content="noindex, nofollow">

It's surprisingly common for developers to add noindex during staging and forget to remove it before launch. An audit catches this immediately.

Open Graph and Structured Data

While not direct ranking factors, Open Graph tags control how your page appears when shared on social media, and structured data (JSON-LD) helps search engines understand your content type — which can unlock rich results in search.

The SEO audit checks for the presence of basic Open Graph tags and flags missing structured data opportunities.

Common SEO Issues Found During Audits (And How to Fix Them)

Missing or Duplicate Title Tags

Fix: Write a unique title tag for every page. Use your primary keyword near the beginning, keep it under 60 characters, and make it compelling enough to earn a click.

No Meta Description

Fix: Write a 150–160 character summary that includes your target keyword and a clear value proposition. Think of it as a mini-ad for your page in search results.

Multiple H1 Tags

Fix: Keep exactly one H1 per page. If your CMS is generating extra H1 tags (common with some WordPress themes), inspect your page source and adjust your theme or template.

Images Without Alt Text

Fix: Go through your page and add descriptive alt text to every meaningful image. Decorative images (spacers, backgrounds) can use an empty alt attribute (alt=""), which tells screen readers to skip them.

Missing Canonical Tags

Fix: Add a self-referencing canonical tag to every page. Most CMS platforms (WordPress with Yoast/RankMath, Shopify, etc.) handle this automatically, but it's worth verifying.

How to Check SEO Score Across Multiple Pages

A single-page audit gives you a starting point, but a thorough SEO review means auditing your most important pages individually. Here's a practical workflow:

Start with your top 10 pages — use Google Analytics or Search Console to identify the pages that drive the most traffic or have the most ranking potential
Audit each one using the SEO Audit tool
Create a simple spreadsheet with columns for URL, title tag status, meta description status, H1 status, image alt text, and canonical tag
Prioritize fixes by impact — pages closest to ranking on page one deserve attention first
Re-audit after making changes to confirm improvements registered correctly

This systematic approach turns a one-time score check into an ongoing optimization process.

What a Good SEO Score Looks Like

There's no universal standard — different tools weight factors differently. But as a general benchmark:

Score Range	What It Means
90–100	Excellent — most best practices followed
70–89	Good — minor issues to address
50–69	Fair — several significant gaps
Below 50	Poor — foundational issues need immediate attention

Don't fixate on hitting a perfect 100. A score of 85 with all critical issues resolved will outperform a score of 95 with a few high-impact problems left unaddressed. Use the score as a directional guide, not an absolute goal.

Beyond the SEO Score: Other Technical Factors That Affect Rankings

Your SEO audit score covers on-page optimization, but search rankings also depend on technical performance factors. Once you've addressed your SEO score issues, consider these additional checks:

Page speed — slow pages rank lower and lose visitors. Run your site through the Website Performance Analyzer to get Lighthouse-based performance metrics
Mobile-friendliness — Google uses mobile-first indexing, meaning your mobile experience is what gets evaluated for rankings. Check this with the Mobile Insights tool
SSL certificate — HTTPS is a confirmed ranking signal. Verify your certificate is valid and properly configured using the SSL Certificate Checker
Structured data — adding JSON-LD markup can unlock rich results. Use the JSON-LD Structured Data Generator to create properly formatted markup for your content type
Sitemap — a well-structured sitemap helps search engines discover and crawl your pages. Generate one with the Sitemap Generator

Each of these factors compounds with your on-page SEO. A page with a strong SEO score, fast load time, mobile-optimized layout, and valid structured data is positioned to rank significantly better than a page that only has one or two of those things right.

How Often Should You Check Your SEO Score?

SEO isn't a one-time task — it's ongoing maintenance. Here's a reasonable cadence:

After major content updates — any time you significantly edit a page, re-audit it to make sure nothing got accidentally broken
After CMS or theme updates — platform updates can sometimes reset meta tags, remove canonical tags, or change heading structures
Monthly for key pages — your most important landing pages and highest-traffic content deserve regular review
After technical changes — if your developer makes changes to the site structure, URL patterns, or template files, run audits on affected pages

Setting a reminder to audit your top 10–20 pages once a month takes about 30 minutes and can catch issues before they compound into ranking drops.

Conclusion

Knowing how to check your website's SEO score is the first step toward making informed, targeted improvements to your search visibility. Rather than guessing what might be wrong, an audit gives you a specific, prioritized list of issues to address — from missing title tags to unoptimized images to broken canonical configurations.
