Technical SEO
Technical SEO is the practice of optimizing your website's infrastructure so search engines can efficiently crawl, index, and rank your pages. It includes site architecture, page speed, mobile optimization, structured data, XML sitemaps, canonical tags, and crawl budget management.

Why Technical SEO Matters for SaaS Companies
The best content in the world will not rank if search engines cannot find or process it. Technical SEO is the foundation that content and link building are built on. For SaaS companies — especially those with dynamic content, JavaScript-heavy frontends, or programmatic pages — technical issues are often the invisible barrier between good content and good rankings.
An Operator's Take
At ZoomInfo, we created hundreds of thousands of pages of valuable content. But traffic was not growing proportionally. The problem was technical: our JavaScript-rendered pages were not being properly crawled, internal linking was sparse (many pages were orphaned), and our sitemap was a single file trying to list 500K URLs. We rebuilt the technical foundation: server-side rendering for SEO-critical pages, tiered sitemaps by content type, and automated internal linking. Traffic grew 2,653% over the following period. The content was always good — the infrastructure was the bottleneck.
Common Mistakes
What I see go wrong at Seed to Series B companies.
Building a JavaScript-heavy frontend without ensuring search engines can render it. Use server-side rendering or static generation for SEO-important pages.
Not submitting an XML sitemap or relying on a single sitemap for large sites. Segment sitemaps by content type and update them when pages change.
Ignoring Core Web Vitals. Page speed directly affects rankings and user experience. Optimize Largest Contentful Paint, First Input Delay, and Cumulative Layout Shift.
Not implementing structured data. Schema markup helps search engines understand your content and can earn rich snippets in search results.
What to Do This Week
Concrete steps you can take right now.
Run a technical SEO audit using Screaming Frog or Ahrefs Site Audit. Focus on crawlability, indexation errors, and page speed.
Verify your XML sitemap is submitted in Google Search Console and reflects your current page inventory.
Check Core Web Vitals in Google Search Console. If any metrics are in the 'Poor' range, prioritize fixes.
Implement structured data (JSON-LD) on your key page types: product pages, articles, FAQs.
