Technical SEO Audit
A solid technical SEO foundation is the prerequisite for all other SEO success. If Google can't find, read, or trust your site's infrastructure, your content will never rank. 42crawl's technical audit covers the four pillars of site health to ensure you're always ready to compete in both traditional search and generative engine optimization.
1. Link Health & Authority Flow
Internal links are the "roads" an SEO crawler uses to navigate your site. Broken roads lead to lost rankings.
- 404 Errors: We find links leading to dead pages that frustrate users and waste crawl budget.
- Redirect Chains: We flag "hops" (A -> B -> C) that slow down bots and dilute link equity.
- Broken External Links: We ensure you aren't linking out to low-quality or dead neighborhoods.
- Orphan Detection: We find pages that have zero internal links pointing to them.
2. Crawlability & Indexability
Can search engines actually see your content? We audit the "gatekeepers":
- Robots.txt Analysis: We ensure you aren't accidentally blocking your most profitable pages.
- Sitemap Validation: We cross-reference your XML sitemap with our crawl results to find "orphans."
- Indexing Directives: We audit your
noindexandnofollowtags to ensure they match your strategy. - Canonical Audit: We verify that every page has a "source of truth" URL to prevent duplicate content issues.
3. Site Performance & Core Web Vitals
In 2026, speed is a first-class ranking factor. 42crawl measures the "Vital Signs" of your site:
- TTFB: The speed of your server's first response.
- Core Web Vitals: Interactive metrics like LCP, CLS, and INP. Read our CWV Guide.
- HTML Bloat: Identification of oversized pages that slow down rendering.
4. Logical Content Structure
We check the "Skeleton" of your pages to ensure they are legible to both humans and AI bots for better GEO optimization:
- Heading Hierarchy: We flag missing or duplicate H1s and skipped levels (e.g., H1 to H3).
- Metadata Health: We ensure your Title Tags and Meta Descriptions are the perfect length for the SERPs.
- Alt Text: We identify images missing the descriptive text needed for SEO and accessibility.
