On-page SEO is the practice of optimizing individual web pages to rank higher and earn more relevant traffic from search engines. Unlike off-page SEO (backlinks, citations), on-page SEO is entirely within your control. Get it right, and you give every page on your site the best possible chance of ranking.
This guide covers every on-page element that matters, with specific rules and examples for each. For the full SEO picture, pair this with our keyword research guide and SEO strategies for small businesses.

Frequently Asked Questions
What is on-page SEO?
On-page SEO refers to optimizations made directly on your website pages to improve search engine rankings. This includes title tags, meta descriptions, header tags, content quality, internal linking, image alt text, and URL structure.
How long should a title tag be?
Title tags should be 50–60 characters long. Google typically displays the first 50–60 characters in search results. Include your primary keyword near the beginning of the title.
How long should a meta description be?
Meta descriptions should be 150–160 characters. They don't directly affect rankings but influence click-through rates. Write compelling descriptions that include your keyword and a clear call to action.
How many H1 tags should a page have?
One H1 per page. The H1 is your main heading and should include your primary keyword. Multiple H1s confuse search engines about the page's main topic.
Does content length affect SEO?
Content length matters less than content quality. A 500-word page that fully answers a question outperforms a 3,000-word page padded with filler. That said, comprehensive content tends to rank better for informational queries.
