TechnicalSEO Agency
Fix What's Stopping You From Ranking
Your content can't rank if Google can't crawl it. We fix the infrastructure first.
Most SEO problems are technical ones: crawl blocks, indexation errors, slow load times, broken site architecture. These errors end up making everything else you invest in less effective.
According to analysis across large-scale site crawls, 35% of websites have critical technical issues that keep their pages from being properly indexed. We find them, prioritize them, and fix them.
Why choose SEO Alive as your technical SEO agency?
We implement, not just audit
Most technical SEO agencies hand you a spreadsheet and call it a day. We stay through implementation: coordinating with your dev team, verifying fixes, and retesting after deployment. A diagnosis with no follow-through doesn't move rankings.
We diagnose, and we strategize
Before implementing anything, we see which issues are actually costing you rankings versus which ones are noise, and we build a roadmap that sequences fixes by impact, not by severity. That means your dev resources go where they move the needle first.
We connect technical SEO to your full organic strategy
Technical fixes only pay off when they feed the rest of your organic strategy. We align the technical foundation with your content, link building, and AI search efforts, so every other investment you make actually compounds instead of leaking through crawl and indexation gaps.
We stay current with how Google crawls and renders websites
Google's crawling and rendering behavior changes constantly. Mobile-first indexing, INP replacing FID as a Core Web Vitals metric, and changes to how Googlebot handles JavaScript are some of the shifts that can affect your rankings. We track them and adjust your strategy to avoid visibility drops.
Our technical SEO services
Technical SEO audit
We make a systematic audit of every layer that affects how Google accesses and ranks your site: crawlability, indexation, site architecture, rendering, Core Web Vitals, structured data, internal linking, and log file analysis.
AI SEO visibility
Your site needs to be optimized for two audiences: Google's crawler and the AI models that retrieve and cite content. We check for both.
We also use AI automation to handle the data layer via SEOcrawl's MCP, giving AI assistants direct access to your site's crawl data, Search Console performance, and technical health signals.
Crawlability and indexation fixes
If Google can't reach your pages, nothing else matters. We identify and fix crawl blocks (robots.txt errors, noindex misconfigurations, orphaned pages, redirect chains) and verify that the pages you want indexed are accessible.
Core Web Vitalsand page speed optimization
Core Web Vitals are a confirmed ranking factor. We audit your LCP, INP, and CLS scores by page type, identify the specific issues causing poor performance (unoptimized images, render-blocking resources, layout shifts), and work with your dev team to fix them.
Site architectureand internal linking
We audit your internal linking structure, identify equity leaks and orphaned content, and rebuild the architecture to support your most important pages.
Schema markupand structured data
72% of first-page results use schema markup. We implement the structured data your site needs so Google can understand your content and serve it in rich results, AI Overviews, and voice search responses.
JavaScript SEO
If your site relies on JavaScript for critical content, navigation, or internal links, there's a real risk that Googlebot isn't seeing what users see. We audit how your JavaScript renders and fix the gaps between what you publish and what gets indexed.
Site migrations
Domain changes, platform migrations, HTTPS transitions, and URL restructures all carry significant ranking risk. We plan migrations with a full technical safety net to protect your organic traffic throughout the process.
Log file analysis
Log files tell you what Google crawls, how often, and which pages it ignored. We analyze your server logs to identify crawl waste, prioritization problems, and sections of your site that Googlebot treats as low-value. And we fix them.
Technical SEO for your site type
SaaS and B2B
JavaScript-heavy apps, dynamic content, and login-gated pages create indexation gaps that standard SEO audits miss. We diagnose what Googlebot actually sees versus what your users see, and close that gap.
eCommerce
Large product catalogs generate duplicate content, thin pages, and crawl budget problems at scale. We fix faceted navigation, canonicalization, and product page structure so your highest-value pages get crawled and indexed.
International and multi-location sites
Hreflang errors, duplicate content between language versions, and incorrect geo-targeting are among the most common causes of poor international rankings. We audit and fix the full technical stack for multi-language and multi-region sites.
Publishers and content sites
High-volume content sites need crawl budget managed precisely. We audit your internal linking, sitemap structure, and canonicalization to ensure your freshest and most valuable content gets prioritized by Googlebot.
WordPress
WordPress powers a significant portion of the web—and comes with a predictable set of technical SEO problems: plugin conflicts, bloated code, slow load times, and canonicalization issues. We know where the problems hide and how to fix them without breaking your site.

Frequently Asked Questions
+What does a technical SEO agency do?
A technical SEO agency finds and fixes the infrastructure problems that stop search engines from crawling, rendering, and indexing your site properly. That includes crawlability and indexation, site architecture, Core Web Vitals and page speed, structured data, JavaScript rendering, log file analysis, and migrations. The goal is to remove the technical barriers that make the rest of your SEO investment less effective.
+What's the difference between technical SEO and on-page SEO?
On-page SEO focuses on the content of individual pages: titles, headings, keywords, and internal copy. Technical SEO focuses on the infrastructure that lets search engines access and understand that content at all: crawling, indexation, rendering, site speed, and architecture. Great content on a page Google can't crawl or render won't rank, which is why we fix the technical foundation first.
+How long does technical SEO take to show results?
It depends on the issue. Some fixes, like unblocking crawlable pages or correcting indexation errors, can produce visible changes within days or weeks once Google recrawls. Structural work like architecture changes, Core Web Vitals, and schema tends to compound over the following months. We prioritize fixes by impact so the changes most likely to move rankings happen first.
+What does your technical SEO audit cover?
We systematically audit every layer that affects how Google accesses and ranks your site: crawlability, indexation, site architecture, rendering, Core Web Vitals, structured data, internal linking, and log file analysis. You get a list of issues prioritized by impact, not just severity, so your dev resources go where they matter most first.
+Do I still need technical SEO if my site already ranks?
Yes. Ranking today doesn't mean there's nothing being left on the table, and it doesn't protect you from losing ground. Crawl waste, slow pages, indexation gaps, and rendering issues often cap how far a site can grow, even when it's already performing. Google's crawling and rendering behavior also changes constantly, so a site that's healthy now can develop problems without any change on your end.
+How do you work with our development team?
We don't just hand over a spreadsheet and leave. We translate each issue into clear, prioritized tickets, coordinate directly with your developers, and verify and retest every fix after it's deployed. If you don't have dev resources available, we can scope and manage implementation so the fixes actually get shipped.
+How does technical SEO connect to AI search visibility?
The same technical foundation that helps Google crawl and index your site also determines whether AI models can retrieve and cite your content. Clean architecture, structured data, fast rendering, and accessible pages make your content usable for both Google's crawler and the AI systems behind ChatGPT, Perplexity, Gemini, and Claude. We optimize for both from the start.
