On-page SEO covers everything on your page that influences ranking: the title, headings, content structure, images, internal links and structured data. Unlike off-page factors, you control it completely.
The fundamentals never went away, even as search evolved. Here is the checklist.
Title and meta description
The title tag is the single most important on-page element.
- Under 60 characters, with the primary keyword near the front.
- A unique title for every page.
- A meta description under 160 characters that reads like an answer, not a summary.
Headings and content
- One H1 per page, used once.
- Logical heading hierarchy (H1, H2, H3) that mirrors your outline.
- Content that fully answers the query with original insight.
- Internal links to related pages with descriptive anchor text.
On-page SEO is mostly content discipline. A page that answers the question completely, structured clearly, is 80% of the way there.
Images and schema
- Descriptive, keyword-aware alt text for every image.
- Compressed images in modern formats.
- Relevant structured data: Article, FAQ, Breadcrumb, Product.
The technical basics
One URL per page, clean and readable. One canonical. Fast loading. Mobile-friendly. These are the price of admission.
On-page SEO FAQ
Does keyword density matter?
No. Write naturally. Search engines understand context, and keyword stuffing actively hurts.
How long should a page be?
As long as it needs to fully answer the query. Depth and completeness beat arbitrary word counts.
