Technical SEO is the invisible engine that powers a website’s search visibility. While on-page SEO and content creation take center stage, it is the technical foundation that ensures search engines can access, crawl, and index your site effectively. When it comes to executing a robust technical SEO strategy, agencies like Onely have become go-to partners for B2B companies, especially in the SaaS and enterprise technology sectors.
Onely is known for its deep technical expertise, ability to work directly with engineering teams, and a data-driven approach that ties technical improvements to tangible business outcomes. Their technical SEO reviews are comprehensive and tailored to the unique architecture and goals of each client. In this guide, we'll explore what Onely technical SEO reviews include, why these elements matter, and how they contribute to long-term search success.
Understanding Technical SEO: The Core of Website Performance
Before diving into what Onely reviews include, it's essential to understand the foundational elements of technical SEO. Technical SEO involves optimizing a website’s infrastructure so that search engines can crawl, index, and render content efficiently. Key components include:
- Crawlability and Indexability: Ensuring search engines can access and process all pages.
- Site Speed and Performance: Optimizing load times and Core Web Vitals.
- Mobile Usability: Making sure the site functions well on mobile devices.
- Structured Data and Rich Snippets: Enhancing visibility in search results.
- XML Sitemaps and Robots.txt: Helping search engines navigate the site architecture.
- SSL and Website Security: Ensuring the site is secure and trustworthy.
- Redirects and Broken Links: Maintaining a clean and functional site structure.
Onely’s technical SEO reviews examine all these elements and more. Their approach is not limited to the basics; it extends into advanced areas like JavaScript SEO, AI visibility, and cross-functional collaboration with engineering teams.
Onely’s Technical SEO Review Framework
Onely’s technical SEO reviews are not generic audits. They are structured to align with the business outcomes of the client—specifically, how improvements in technical SEO impact organic traffic, lead generation, and revenue. Here’s a breakdown of what their reviews typically include:
1. Crawling and Indexing Audit
Onely begins by evaluating how search engines are able to access and index the website. This includes:
- Checking for crawl errors in Google Search Console
- Identifying blocked or disallowed content via robots.txt
- Analyzing sitemap structure and submission
- Identifying duplicate content issues
- Detecting thin or low-quality pages
They use tools like Screaming Frog and Google Search Console to crawl the site and identify technical barriers. This step is critical because if search engines can't find your content, your SEO efforts will fall flat.
2. Site Speed and Core Web Vitals Analysis
With Google prioritizing page speed and user experience in its ranking algorithms, Onely places a strong emphasis on performance. Their reviews include:
- Measuring load times using PageSpeed Insights and Lighthouse
- Identifying render-blocking resources
- Analyzing image optimization and compression
- Evaluating the use of caching and CDNs
- Monitoring Core Web Vitals (LCP, FID, CLS)
Improving these metrics not only helps with rankings but also enhances the user experience, leading to higher engagement and conversion rates.
3. Mobile Optimization and Responsive Design
Since mobile traffic now dominates the web, Onely ensures the site is optimized for all devices. Their reviews check for:
- Mobile usability via Google’s Mobile-Friendly Test
- Responsive design that adapts to different screen sizes
- Proper viewport settings and touch-friendly elements
- Performance on mobile networks
A mobile-optimized site is a prerequisite for high rankings in Google's mobile-first index.
4. JavaScript and Dynamic Rendering
Many modern websites use JavaScript frameworks like React or Angular. While this improves the user experience, it can complicate SEO if not handled correctly. Onely specializes in JavaScript SEO and their reviews include:
- Evaluating how JavaScript content is rendered and indexed
- Identifying issues with client-side rendering and search engines
- Suggesting server-side rendering (SSR) or pre-rendering solutions
- Analyzing JavaScript-heavy pages for accessibility and performance
This is where Onely distinguishes itself from generic SEO agencies. They have the technical depth to diagnose and fix complex JavaScript SEO issues.
5. Structured Data and Rich Snippets
Onely ensures that the site is leveraging structured data (schema) to enhance visibility in search results. Their reviews cover:
- Implementing schema markup for key content types (products, articles, events)
- Testing schema with the Schema Markup Validator
- Ensuring rich snippets are appearing in search results
- Aligning structured data with business goals (e.g., product ratings, FAQs, events)
These enhancements can lead to more clicks and better engagement from searchers.
6. Internal Linking and Site Architecture
A well-structured site with strong internal linking helps both users and search engines navigate content. Onely reviews include:
- Evaluating the hierarchy of pages and internal links
- Identifying orphaned pages with no internal links
- Assessing the use of breadcrumbs and site navigation
- Suggesting improvements to site architecture for better flow and discoverability
A logical site structure improves crawl efficiency and helps distribute link equity across pages.
7. Redirects and URL Structure
Onely reviews the site's redirect strategy and URL structure to ensure everything is clean and functional. Key checks include:
- Identifying broken or 404 links
- Evaluating the use of 301 and 302 redirects
- Checking for redirect chains or loops
- Assessing URL readability and SEO-friendliness
- Suggesting improvements for URL structure (e.g., using keywords, avoiding parameters)
A clean URL structure and redirect strategy help maintain link equity and prevent crawl issues.
8. Security and HTTPS
Website security is a ranking factor and a trust signal for users. Onely reviews include:
- Checking if the site is using HTTPS
- Evaluating SSL certificate validity and configuration
- Identifying mixed content issues (HTTP resources on HTTPS pages)
- Ensuring secure forms and login pages
A secure site is not only better for SEO but also essential for compliance and user trust.
9. AI and LLM Visibility
With the rise of AI search and large language models (LLMs), Onely has expanded its technical SEO scope to include AI visibility. Their reviews now assess:
- How the site appears in AI overviews and LLMs
- Whether the content is structured in a way that LLMs can understand
- Whether the site is being used as a source in AI-generated content
- Opportunities to optimize for AI-driven search queries
This forward-looking approach ensures clients remain competitive in an evolving search landscape.
Onely’s Collaboration with Engineering Teams
One of Onely’s standout features is their ability to work directly with engineering teams. Unlike many SEO agencies that deliver reports and leave the implementation to developers, Onely integrates into the development process. Their technical SEO reviews include:

Frequently Asked Questions About Technical SEO
What is technical SEO in simple terms?
Technical SEO is the process of optimizing a website’s infrastructure so that search engines can crawl, index, and render content efficiently. It includes improving site speed, ensuring mobile-friendliness, fixing crawl errors, and making the site secure. Think of it as the engine of a car—users don’t see it directly, but without it, the car won’t run.
How is technical SEO different from on-page SEO?
Technical SEO focuses on the backend infrastructure of a website—how search engines access and interpret content. On-page SEO, on the other hand, deals with the content itself—what users see and read. Technical SEO handles elements like site speed, mobile-friendliness, security (HTTPS), crawlability, and code structure. On-page SEO covers keyword optimization, content quality, meta tags, and internal linking.
Why is technical SEO important?
Technical SEO is crucial because it ensures that search engines can find, understand, and display your website properly. Without a solid technical foundation, even the best content won’t rank well. Technical SEO also impacts user experience, which is a key factor in Google’s ranking algorithms. A fast, secure, and mobile-friendly site is more likely to rank well and convert visitors into customers.
How does technical SEO affect business outcomes?
Technical SEO has a direct impact on business outcomes such as organic traffic, lead generation, and revenue. Improving site speed can increase conversion rates by up to 45%. Fixing crawl errors and indexing issues ensures that all pages are visible in search results. Optimizing for Core Web Vitals can improve rankings and user engagement. By aligning technical SEO with business goals, companies can see measurable improvements in their online performance.
