Content without technical foundations is like pouring water into a leaky bucket. These 15 checks are where we start every SEO engagement — before keyword research, before link building.
Crawlability & indexation
- Robots.txt — Confirm you're not accidentally blocking CSS, JS, or key landing pages.
- XML sitemap — Submit an updated sitemap; exclude thin, duplicate, and noindex URLs.
- Canonical tags — Resolve duplicate content from parameters, trailing slashes, and HTTP/HTTPS variants.
- Internal links — Orphan pages won't rank. Every commercial page needs contextual internal links.
- 404 & redirect chains — Fix broken links and flatten redirect chains to a single hop.
Site speed & Core Web Vitals
- LCP under 2.5s — Optimize hero images, server response time, and critical CSS.
- INP / interactivity — Reduce JavaScript blocking on key landing pages.
- CLS stability — Reserve space for images and ads to prevent layout shift.
On-page structure
- Title tags & meta descriptions — Unique, intent-matched, under character limits.
- Heading hierarchy — One H1 per page; logical H2/H3 structure for sections.
- Image alt text — Descriptive, keyword-natural alt attributes on content images.
Authority signals
- Schema markup — Organization, FAQ, Product, and Article schema where relevant.
- HTTPS everywhere — No mixed content warnings.
- Mobile usability — Responsive design, tap targets, readable font sizes.
Measurement
- Search Console & analytics — Confirm organic landing pages, conversion events, and Search Console coverage are clean.
