Before content or backlinks can do their job, a site needs the technical basics right: fast load times, clean site structure, correct title tags and meta descriptions, and a sitemap search engines can actually crawl. Vandulo audits and fixes these fundamentals as the starting point of every SEO engagement.
What’s Included:
Think of SEO like a building. Content and links are the floors that people see, but technical SEO is the foundation. If search engines can’t crawl your pages efficiently, can’t understand how they relate to each other, or see a slow, unstable experience on mobile, even excellent content can struggle to rank. Many websites we audit have strong services and good writing held back by technical problems the owner never knew existed: pages accidentally blocked from search, duplicate versions of the same page, broken internal links, missing titles, or images so large that pages take far too long to load on a phone.
On-page and technical SEO fixes these issues and makes every page as clear as possible to both search engines and visitors. It’s where every Vandulo SEO engagement begins, because improvements here make all other SEO work more effective.
Title tags. We write unique, descriptive titles for each page that include the main topic naturally and encourage clicks from search results.
Meta descriptions. We write compelling summaries that explain what the page offers and why someone should click. While not a direct ranking factor, good descriptions can improve click-through rates.
Heading structure. We organize content with a single clear H1 and logical H2 and H3 subheadings, which helps readers skim and helps search engines understand topics and subtopics.
Content optimization. We make sure each important page fully answers the questions searchers have, covers related topics, and uses the language your customers use, based on our keyword research. Thin pages are expanded and overlapping pages are consolidated.
Internal linking. We connect related pages with descriptive links so visitors can find what they need and search engines can understand your site’s structure and which pages matter most.
Image optimization. Descriptive file names, helpful alt text, modern formats, and appropriate compression make images accessible and fast.
URL structure. Short, readable URLs that reflect site hierarchy are easier for people and search engines to understand.
Crawlability and indexing. We review robots.txt rules, meta robots tags, XML sitemaps, and Google Search Console coverage reports to make sure the pages you want found are crawlable and indexed, and that low-value pages aren’t wasting crawl attention.
Duplicate content and canonicalization. We fix issues such as multiple URL versions of the same page, parameter-based duplicates, and HTTP versus HTTPS or www versus non-www conflicts, using redirects and canonical tags.
Redirects and broken links. We find and fix 404 errors, redirect chains, and broken internal and external links that waste link value and frustrate visitors.
Core Web Vitals. Google’s Core Web Vitals measure real-world user experience: Largest Contentful Paint (how quickly the main content loads), Interaction to Next Paint (how quickly the page responds to taps and clicks, which replaced First Input Delay in 2024), and Cumulative Layout Shift (how much the layout jumps around while loading). We diagnose and improve these through image optimization, code and plugin cleanup, caching, font loading, and server performance. See our guide to website speed and Core Web Vitals.
Mobile usability. Google uses mobile-first indexing, meaning it evaluates the mobile version of your site. We make sure text is readable, buttons are easy to tap, and content is equivalent on mobile and desktop.
Structured data. We add schema markup, such as Organization, LocalBusiness, Service, Product, FAQ, Article, Breadcrumb, and Review, to help search engines understand your content and make pages eligible for rich results where applicable.
Security. HTTPS is a baseline expectation. We verify that your SSL certificate is working correctly and that there are no mixed-content warnings.
JavaScript and rendering. For sites built with heavy JavaScript frameworks or page builders, we check that important content and links are visible to search engines when pages are rendered.
AI-powered search features and AI assistants also need to access and understand your content. Clean HTML structure, clear headings, structured data, fast pages, and sensible crawler access rules make it easier for these systems to interpret and cite your pages. We review how your robots.txt handles AI crawlers, such as those used by OpenAI and Google, so your choices about AI access are deliberate rather than accidental. This technical work supports our AI search optimization service.
1. Crawl and audit. We crawl your site with professional SEO tools, review Google Search Console and Analytics data, and test performance on real devices. 2. Prioritized report. You receive a clear list of issues ranked by impact and effort, explained in plain language. 3. Implementation. Because Vandulo is also a web development company, we can fix issues directly instead of handing you a report for someone else to implement. 4. Validation. We verify fixes in Search Console and re-test performance. 5. Monitoring. Ongoing monitoring catches new issues introduced by site updates, plugins, or content changes.
Most of these issues are invisible to business owners but obvious to search engines. Fixing them often produces some of the quickest SEO improvements available.
A website redesign is one of the riskiest moments for SEO. New URLs, changed content, removed pages, and different site structures can wipe out rankings overnight if they aren’t planned carefully. We protect your search visibility by mapping every old URL to its new equivalent, carrying over valuable content and metadata, testing the new site before launch, and monitoring closely afterward. If you’re planning a new site, involving SEO from the beginning through our website design and development team saves costly recovery work later.
Many technical SEO best practices also make your site more accessible to people with disabilities: descriptive alt text, logical heading structure, sufficient color contrast, descriptive link text, and keyboard-friendly navigation. Following Web Content Accessibility Guidelines (WCAG) helps more people use your website and reduces legal risk, while also producing cleaner, better-structured pages that search engines understand more easily. We flag accessibility improvements as part of every audit.
FAQ
Why does technical SEO matter if my content is good?
Search engines need to be able to crawl and understand your site before content quality even factors in — technical issues can suppress an otherwise strong page.
Will this fix broken links or slow pages on my current site?
Yes, technical SEO audits typically surface exactly these kinds of issues for repair.
How often should a technical audit be done?
A full audit is recommended at least annually and after major site changes, with ongoing monitoring in between.
Will fixing technical issues improve rankings immediately?
Some fixes, such as unblocking pages or fixing indexing issues, can have a fairly quick effect. Others, like performance improvements, contribute gradually alongside content and authority.
Do you work on any platform?
Yes. We work on WordPress, Shopify, Squarespace, Wix, Webflow, and custom-built sites.
