Technical SEO Audit

Crawlability and Indexation

Before Google can rank your pages, it has to find them, crawl them, and add them to its index. When any step in that process breaks down, your pages simply don't appear in search results — no matter how good the content is. Crawlability and indexation problems are among the most serious technical SEO issues because they affect visibility at the most fundamental level.

Robots.txt and Noindex Tags

The robots.txt file tells search engine crawlers which pages they're allowed to access. A misconfigured robots.txt — something as simple as a stray Disallow: / directive — can block an entire website from being crawled. We've audited sites where entire service sections or product categories were inadvertently blocked from Google's crawlers for months, silently erasing rankings that had taken years to build.

Noindex meta tags instruct Google not to include a page in its index. These are legitimate tools when used intentionally — for thank-you pages, admin areas, or duplicate content. But when noindex tags are applied to pages that should rank, or when a staging environment's noindex configuration accidentally carries over to the live site at launch, the result is complete invisibility for the affected pages.

XML Sitemaps and Crawl Errors

An XML sitemap is a structured list of your site's URLs that helps Google discover and prioritize pages for crawling. A well-maintained sitemap includes only canonical, indexable URLs — not 404 pages, redirects, or noindexed content. Many sites have outdated sitemaps that include deleted pages, redirect chains, or URLs that no longer exist, which wastes crawl budget and creates confusing signals for Google's systems.

Crawl errors — the 404s, 500s, and soft 404s that Google encounters when attempting to access your pages — are logged in Google Search Console. We analyze these errors in full, distinguishing between legitimate 404s (pages that should be gone) and unintentional 404s (pages that exist but are linked to with incorrect URLs). Fixing broken internal links and setting up appropriate redirects is often one of the quickest wins in a technical audit.

Site Speed and Core Web Vitals

Google has made page experience — including site speed and Core Web Vitals — an explicit ranking factor. Slow pages frustrate users, increase bounce rates, and signal lower quality to Google's systems. Technical SEO audits evaluate site speed at both the page level and the server level, identifying the specific bottlenecks responsible for poor performance.

Largest Contentful Paint (LCP)

LCP measures how long it takes for the largest visible element on a page — typically a hero image or headline — to load and render in the viewport. Google considers LCP scores under 2.5 seconds "good," 2.5–4.0 seconds "needs improvement," and above 4.0 seconds "poor." Common LCP issues include unoptimized hero images, slow server response times, render-blocking JavaScript, and missing preload directives for critical resources. We identify the root cause of LCP failures and provide specific technical fixes — not just the score.

Interaction to Next Paint (INP) and Cumulative Layout Shift (CLS)

INP replaced First Input Delay (FID) as the responsiveness metric in the Core Web Vitals set. It measures the delay between a user's interaction (click, tap, key press) and the browser's visual response. Poor INP scores are typically caused by heavy JavaScript execution that blocks the main thread. Cumulative Layout Shift (CLS) measures visual stability — how much page elements move around unexpectedly while loading. Ads that load late, images without defined dimensions, and dynamically injected content are common CLS culprits. Both metrics directly affect how Google evaluates page experience signals.

Mobile-Friendliness

Google's indexing is mobile-first, which means it primarily uses the mobile version of your site for ranking and indexation decisions. A site that looks and performs well on desktop but delivers a poor mobile experience is being evaluated on its worst version. Mobile SEO issues are frequently the cause of ranking drops that businesses incorrectly attribute to algorithm updates or content quality problems.

Our mobile audit checks responsive design implementation (do all elements reflow properly at mobile screen widths?), tap target sizing (are buttons and links large enough to tap without precision tapping?), font size legibility (does text remain readable without zooming?), and mobile page speed (mobile connections are slower — mobile-specific speed issues often differ from desktop ones). We test across multiple device emulations and flag specific implementation failures rather than generic mobile compatibility scores.

Canonical Tags and Duplicate Content

Duplicate content — multiple URLs that serve identical or very similar content — confuses Google about which version of a page to rank. It splits ranking signals across multiple URLs instead of concentrating them on a single canonical version, which dilutes the authority of all variations and can suppress rankings across the board.

Canonical Tag Implementation

The canonical tag (<link rel="canonical">) tells Google which URL you consider the authoritative version of a page. Every page should have a self-referencing canonical tag. When multiple URLs serve the same content (paginated pages, filtered product listings, URL parameter variations), the canonical should point to the primary version. We audit canonical implementations for correctness — checking that canonicals point to the right URLs, that they're consistent between HTML and HTTP headers, and that no canonicalization loops exist.

Common Duplicate Content Scenarios

The most frequent duplicate content sources we find include: www vs. non-www versions (both serving content without a redirect to a single preferred version), HTTP vs. HTTPS versions (the old HTTP version still accessible after an SSL migration), trailing slash variations (/services/ and /services both returning 200 status), session ID parameters in URLs (creating thousands of unique URLs with identical content), and printer-friendly pages or other content format variations that aren't properly canonicalized.

Structured Data Audit

Structured data is code — typically JSON-LD format — added to pages to help Google understand content in a machine-readable way. It enables rich results (star ratings, FAQ dropdowns, event listings) and feeds Google's AI systems. A structured data audit evaluates which pages have schema markup, which are missing it, and whether existing implementations are valid and correctly implemented.

We validate all structured data against Google's Rich Results Test and the Schema.org specification, identifying errors that would prevent rich result eligibility and warnings that indicate implementation gaps. Common structured data failures include referencing images that don't exist, using deprecated schema types, implementing schema that doesn't match the visible page content (which violates Google's guidelines), and missing required properties for specific schema types.

Crawl Budget Optimization

Crawl budget refers to the number of pages Google is willing to crawl and index from your site within a given timeframe. For smaller sites (under 1,000 pages), crawl budget is rarely a concern. For larger sites — e-commerce platforms, news sites, or websites that have grown organically over many years — crawl budget management becomes critical. Google's crawlers have finite capacity, and if your site wastes their time on low-value pages, high-value pages get crawled less frequently or not at all.

Internal Link Depth and Orphan Pages

Pages that require many clicks to reach from the homepage (link depth greater than three or four) are crawled less frequently by Google's crawlers. Orphan pages — pages with no internal links pointing to them — may not be crawled at all. We map your site's complete link graph to identify pages that are buried too deep in the architecture and pages that are completely disconnected from the rest of the site.

Redirect Chains and Loops

Every redirect wastes a portion of crawl budget and reduces the link equity that flows through to the final destination. A redirect chain — URL A redirects to URL B which redirects to URL C — is significantly worse than a single direct redirect. Redirect loops, where pages redirect to each other in a circle, cause crawlers to give up entirely. We map all redirect paths on your site and flag chains longer than one hop for consolidation.

What You Receive: Audit Deliverables

Our technical SEO audit delivers a comprehensive, prioritized report that gives you and your development team everything needed to implement fixes. The deliverable is structured around impact and urgency — not alphabetical lists of issues that leave you guessing what to fix first.

The audit report includes: a complete crawl export of all indexable pages with their technical properties, a prioritized issue list with severity ratings (Critical / High / Medium / Low), specific fix recommendations for each issue including exact code changes where relevant, baseline metrics (Core Web Vitals scores, crawl error counts, index coverage) to measure improvement against, and a quick-win section that identifies the ten highest-impact fixes that can typically be implemented within a week.

How Long a Technical Audit Takes

A thorough technical SEO audit takes between two and three weeks for most websites. Rushed audits miss important issues. The timeline breaks down as: crawl and data collection (two to three days), analysis and issue identification (four to five days), competitive technical benchmarking (two to three days), report writing and prioritization (three to four days), and a review call with your team to walk through findings and answer questions. For very large sites (100,000+ pages), we may scope additional time for crawl analysis.

Common Technical Issues We Find

After auditing dozens of business websites, the same technical problems appear repeatedly. The most common and impactful include:

• Missing or duplicate H1 tags: Multiple pages sharing an H1, or pages with no H1 at all — often caused by CMS template issues that apply the site name rather than the page-specific headline.
• Slow server response times: TTFB (Time to First Byte) above 600ms, indicating server-level performance problems that affect every page on the site regardless of other optimization efforts.
• Broken internal links: Links pointing to 404 pages that waste crawl budget and create dead ends in the user experience.
• Mixed content warnings: Pages served over HTTPS that still load resources (images, scripts, stylesheets) over HTTP — causing browser security warnings and potential indexation issues.
• 302 redirects instead of 301s: Temporary redirects (302) used in places where permanent redirects (301) are appropriate, resulting in partial link equity transfer instead of full pass-through.
• Pages indexed that shouldn't be: Thank-you pages, admin pages, search results pages, or parameter-generated URLs that are unnecessarily indexed and diluting overall site quality signals.

JavaScript Rendering and SPA Technical SEO

JavaScript-heavy websites — those built with React, Angular, Vue, or other single-page application frameworks — present unique technical SEO challenges that standard HTML sites don't share. When a page renders its content via JavaScript, Googlebot has to execute that JavaScript to see the content, a process that happens on a delayed second wave of crawling. During the window between first crawl and JavaScript rendering, your content may be partially or completely invisible to Google.

The specific problems we audit in JavaScript environments include: content that only exists after JavaScript execution (not in the initial HTML response), internal links that are rendered by JavaScript and may not be discovered during the initial crawl, lazy-loaded content that Google's crawler may not trigger in the same way a human browser would, and dynamically injected meta tags (title, description, canonical) that may not be read correctly if they're set after the initial page load. We test how Google actually renders your pages using server-side render testing and Google's URL Inspection tool, identify the gap between what Google sees and what users see, and provide specific implementation guidance for each rendering failure.

For businesses on SPA frameworks, server-side rendering (SSR) or static site generation (SSG) are the strongest solutions to JavaScript SEO problems. We evaluate whether your current implementation would benefit from these architectures and what the transition would require. For cases where a full architectural change isn't feasible, we identify which content must be in the initial HTML response versus what can safely remain JavaScript-rendered.

Site Migration Technical SEO

Site migrations — moving from HTTP to HTTPS, changing domains, restructuring URL architecture, migrating between CMS platforms, or redesigning site structure — are among the highest-risk technical SEO events a website can undergo. A migration executed without proper technical SEO planning can destroy years of accumulated rankings in a matter of weeks. We provide technical SEO planning and validation for every type of migration.

The critical elements of a safe migration include: comprehensive redirect mapping (every old URL that should be indexed and ranked must have a corresponding 301 redirect to its new equivalent), pre-migration crawl baseline (a complete snapshot of your site's current technical state and rankings to compare against post-migration), canonical tag update across all pages, XML sitemap update with new URLs, and Search Console re-verification and new sitemap submission. Post-migration monitoring for the first 30 to 90 days is essential — most migration-related ranking impacts are detected and corrected during this window.

We have managed technical SEO for domain migrations, HTTPS migrations, CMS migrations from platforms like Wix and Squarespace to WordPress or custom builds, and full site restructures where URL architecture changed significantly. In each case, the approach begins with a pre-migration audit that identifies every high-risk element and produces a migration checklist validated against Google's site migration documentation.

Hreflang and Multilingual SEO for Florida Businesses

South Florida's bilingual market creates a specific technical SEO challenge for businesses running English and Spanish content. Hreflang tags are the technical mechanism that tells Google which version of a page is intended for which language audience — preventing the two versions from competing against each other in search results and ensuring Spanish searchers find the Spanish content and English searchers find the English content.

Hreflang implementation is technically precise and frequently done incorrectly. Every page in one language must reference its equivalent in the other language, and both pages must reference each other for the relationship to be recognized. Missing reciprocal hreflang, hreflang pointing to non-canonical URLs, and hreflang that conflicts with canonical tags are the three most common errors we find in multilingual technical audits. Any of these errors can cause Spanish and English versions to compete for the same rankings rather than serving their respective audiences.

Our technical audits specifically evaluate multilingual SEO implementation for businesses with dual-language content, covering hreflang tag correctness, language meta tag consistency, URL structure for language variants (subdirectory versus subdomain versus ccTLD), and canonical tag relationships between language variants. For businesses considering adding Spanish content, we provide the technical framework for implementation before any content is created.

When to Commission a Technical SEO Audit

A technical SEO audit is most urgently needed after any significant technical event and most productively used as a proactive health check. The events that most commonly require immediate audit include a sudden unexplained traffic drop (technical issues are the most common cause of acute drops), completion of a site redesign or platform migration, launch of a new site, a significant CMS update that may have changed template-level elements, or preparation for an SEO program launch where you need a clean technical baseline.

Proactive audits — conducted annually even when no specific problem has been identified — catch issues before they become ranking problems. Websites accumulate technical debt over time: pages are added without proper canonical tags, redirect chains grow as content is reorganized, images are added without alt text, JavaScript is layered on without performance consideration. An annual technical audit identifies this accumulating debt and provides a clear remediation roadmap before it reaches the threshold where it materially affects rankings.

Frequently Asked Questions

Can a technical SEO audit be performed on any type of website?

Yes. We audit static HTML sites, WordPress installations, Webflow sites, Shopify stores, custom-built applications, and enterprise platforms. The tools and specific checks differ by platform — a Shopify audit has different considerations than a WordPress audit — but the fundamental technical SEO principles apply universally. For enterprise and custom-built sites, we may require collaboration with your development team to access certain data, but the audit process itself is platform-agnostic.

Do you fix the issues you find, or just report them?

We can do either, depending on your preference and the complexity of the fixes. For some clients, we deliver the prioritized audit report and their development team handles implementation. For others, we implement all the fixes directly. For clients on retainer, we handle ongoing technical issue detection and remediation as part of the ongoing engagement. In every case, the audit deliverable includes specific, implementable fix recommendations — not just problem identification. If we identify a technical issue, we tell you exactly what needs to change to resolve it.

What is the difference between a technical SEO audit and an on-page SEO audit?

Technical SEO audits evaluate the infrastructure that allows search engines to access, crawl, and index your site — server configuration, crawlability, redirects, site speed, structured data, Core Web Vitals, JavaScript rendering, and canonicalization. On-page SEO audits evaluate the content and relevance signals on individual pages — title tags, heading structure, keyword targeting, content depth, internal linking, and image optimization. Both are necessary for a complete SEO program. Technical audits deal with the foundation; on-page audits deal with what's built on top of that foundation. A site with excellent on-page optimization but technical problems that prevent crawling will not rank. A site with perfect technical implementation but poor on-page optimization may get crawled but still won't rank for competitive keywords.

How often should we get a technical SEO audit?

At minimum, a comprehensive technical audit should be conducted annually, with a focused re-audit immediately following any significant site change (migration, redesign, major CMS update). Businesses actively running SEO programs benefit from quarterly technical health checks that focus on newly accumulating issues rather than a full audit from scratch. Search Console monitoring provides continuous insight into crawl errors and Core Web Vitals performance, and we include monitoring as part of ongoing client engagements. For businesses in highly competitive markets or with high-volume sites, monthly crawl reviews to catch and address issues before they compound are standard practice.
