Technical

Site has a valid robots.txt

XML sitemap submitted to Search Console

Core Web Vitals pass (LCP < 2.5s, CLS < 0.1, INP < 200ms)

HTTPS enforced sitewide, with no mixed-content warnings

Canonical tags present on every indexable page

No broken internal links (404s) found in a full site crawl

Mobile-responsive on every template, not just the homepage

Structured data validates with zero errors (Rich Results Test)

On-Page

Every page has a unique, descriptive title tag (~50-60 characters)

Every page has a unique meta description (~150-155 characters) written to earn the click

Exactly one H1 per page, matching that page's search intent

Heading hierarchy (H1 → H2 → H3) is logical, with no skipped levels

Primary keyword or topic appears naturally in the title, H1, and opening paragraph

All meaningful images have descriptive alt text, not left blank or as a bare filename

Internal links use descriptive anchor text instead of "click here" or "read more"

URLs are short, readable, and hyphen-separated, without session IDs or stacked parameters

Trust & Authority

Every article has a visible, real author byline, ideally backed by Person schema

Business name, address, and phone (NAP) match exactly across the site, Google Business Profile, and directories

Backlink profile has been reviewed for spammy or irrelevant links, with a disavow file ready if needed

A genuine handful of backlinks exist from credible, topically-relevant sites in the industry

About and contact pages clearly identify who operates the site with a real way to reach them

Reviews, ratings, or testimonials shown are genuine and accurately marked up — never fabricated review schema

Social/professional profiles are linked and consistent with the business's real identity

Search Console shows no manual actions or security issues on the domain
