description: Audit and rewrite pages to rank, without keyword stuffing.

SEO Optimizer

Improve organic visibility through content quality, technical signals, and structured data.

Audit checklist

Title tag: 50-60 chars, primary keyword near the front, unique per page.
Meta description: 140-160 chars, includes a call to action. Not a ranking factor but drives CTR.
One <h1> per page; logical <h2>/<h3> hierarchy.
URL slug: short, hyphenated, keyword-bearing, no stop words.
Internal links: 2-5 contextual links to related pages with descriptive anchor text.
Image alt text describing the image, not keyword-stuffed.

Keyword strategy

Target one primary keyword plus 2-4 semantic variants per page.
Aim for natural density (~0.5-1.5%). Optimize for topic coverage, not exact-match repetition.
Map search intent: informational, navigational, transactional. Match content type to intent.
Answer the query in the first 100 words for featured-snippet eligibility.

Schema markup

Add JSON-LD in the <head>:

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Article",
  "headline": "${title}",
  "author": { "@type": "Person", "name": "${author}" },
  "datePublished": "${isoDate}"
}
</script>

Use FAQPage, Product, BreadcrumbList, and HowTo where they fit the content.

Core Web Vitals

LCP under 2.5s: preload the hero image, serve next-gen formats, avoid render-blocking CSS.
CLS under 0.1: set explicit width/height on images and reserve space for ads/embeds.
INP under 200ms: break up long tasks, defer non-critical JS.

Rules

Never cloak or stuff. Google's helpful-content system penalizes thin, AI-spun pages.
Each page must serve a distinct intent — consolidate cannibalizing pages.
Canonicalize duplicates with rel="canonical".
Submit an XML sitemap and keep it under 50k URLs per file.

Edge cases

Pagination: use self-referencing canonicals, not rel=prev/next (deprecated).
JS-rendered content: ensure server-side rendering or dynamic rendering so crawlers see text.
Migrations: 301-redirect old URLs one-to-one; never mass-redirect to the homepage.
