On-page SEO checklist: 24 fixes for higher rankings in 2026

On-page SEO checklist: 24 fixes for higher rankings in 2026

Most on-page SEO failures fall into three buckets. Missing signals — no schema, no meta, no internal links — cost you citations in AI search. Broken signals — duplicate titles, thin content, wrong heading hierarchy — stop Google from reading the page correctly. Invisible signals — image alt text, LCP image format, reading ease — work against you without you knowing. Here is what to check in each bucket before you publish.

Bucket 1: missing signals

Title tag. 50 to 60 characters. Primary keyword first. Brand name last only when it fits naturally within the character limit. Every page gets a unique title.

Meta description. 140 to 160 characters. Not copied from another page. Describes what the page is, who it is for, and what the user should do next.

Schema. BreadcrumbList on every page. Page-specific schema: Service schema on service pages, FAQPage on informational pages, Article on blog posts. Six to twelve FAQ questions on service, industry and blog pages.

Internal links. At least three contextual links in the body. Descriptive anchor text. Links to related service pages, related blog posts, and at least one page in a different section. See our breakdown of internal link architecture and topical authority for the cluster strategy. Orphan pages — pages no other page links to — do not rank.

Bucket 2: broken signals

H1. Exactly one per page. The H1 is the page’s topic statement. If you have two, you have two topics, and Google does not know which one to rank the page for.

Heading hierarchy. H1, then H2, then H3. Never skip from H2 to H4. Skipped levels confuse screen readers and break the topical outline search engines build from your page.

TL;DR length. Two to three sentences. The TL;DR is a summary, not a compressed version of the article. It is read by GPT, Claude and Perplexity before they decide whether to read further. If it is 300 words, it is doing the job of the article.

Duplicate titles and meta descriptions. Run a crawl before publishing. Any page that shares a title or meta description with another page is a collision. Fix the duplicate before it is indexed.

Content depth. Pages under 300 words struggle to rank for competitive terms. Service and industry pages target 500 to 800 words. Blog posts targeting head terms need 1,000+. Thin content is a ranking signal, not just a quality signal.

Bucket 3: invisible signals

LCP image. One LCP image per page, AVIF or WebP format, preloaded with fetchpriority="high", declared width and height. Every other image lazy-loaded. Our Core Web Vitals 90-day plan covers the full LCP fix sequence with Indian-specific device and network conditions. For how AI search engines process pages that rely on JavaScript for image lazy-loading, see our AI crawler robots.txt governance guide.

Image alt text. Every image gets alt text. Describe what is in the image: “A founder reviewing analytics dashboard on laptop in office.” Not “image1.jpg.”

Reading ease. Target Flesch reading ease between 70 and 95. Short sentences, plain language, active voice. Pages that score below 60 are too complex for reliable automatic summarisation by AI tools.

FAQ schema with 6 to 12 questions. The highest-impact structured data for most pages. It gives AI tools a readable Q&A surface and Google rich result opportunities.
