On-page SEO checklist for business websites

Short answer

An on-page SEO checklist makes sure each page clearly targets one search topic and gives search engines and AI systems what they need to understand it: a descriptive title, a useful meta description, a single clear main heading, helpful content that answers the searcher's questions, internal links, optimised images and structured data.

• Give each page one primary topic and one search phrase; never two pages for the same one.
• Title under about 60 characters with the topic near the front.
• One H1, then question-style H2s that match what people search.
• Answer the main question in the first 100 words.
• Link to and from related pages with descriptive anchor text.

What is on-page SEO?

On-page SEO is the practice of optimising the content and HTML of individual web pages, including titles, headings, text, links, images and structured data, so that search engines can understand them and rank them for relevant searches.

It sits alongside technical SEO, which covers crawling, indexing and speed, and off-page SEO, which covers links and reputation. For small business sites, on-page work is usually where the quickest gains are.

Why does on-page SEO still matter with AI search?

AI answers in Google, Bing and other assistants draw on pages that search engines have indexed and understood. Google's documentation on AI features says the same SEO best practices apply. Pages with clear topics, direct answers and good structure are easier to rank, quote and cite.

What has changed is the value of answer-first writing. Short, self-contained answers under question-style headings are easier for AI systems to lift and for featured snippets to display.

How should you write titles and meta descriptions?

The title tag is the strongest on-page signal and the headline in search results. Keep it descriptive and unique, put the main topic near the front, and aim for roughly 50 to 60 characters so it is not truncated. Google may rewrite titles that are vague or stuffed with keywords.

The meta description does not directly affect rankings, but it influences whether people click. Write 120 to 155 characters that state the answer or benefit and include the topic naturally. Google sometimes shows other text from the page instead.

What does the rest of the page need?

Once the title and description are right, work down the page.

• One H1 that states the page topic clearly.
• H2s phrased as the questions people search, each answered directly beneath.
• The primary phrase in the first 100 words and naturally throughout, never forced.
• Content that covers what top-ranking pages cover, plus what they lack.
• Descriptive internal links to related services and articles.
• Images with descriptive file names and alt text.
• Structured data for the page type: LocalBusiness, Service, Product, Article.
• A clean, readable URL with the topic in it.

• Schema markup for small business websites
• Optimise website images for speed and search

How do you avoid pages competing with each other?

Keyword cannibalisation happens when two of your pages target the same search, splitting signals so both rank lower. Keep a simple list of pages and the primary phrase each one owns, and check it before creating anything new.

If two pages already overlap, merge them into the stronger one and redirect the weaker URL. Link consistently: always use the same anchor text when linking to the page that owns a topic.

When will on-page SEO not move rankings?

On-page work cannot overcome a site that cannot be crawled or indexed, a topic where competitors have far more authority, or content that simply is not as helpful as what already ranks. Check indexing in Search Console first.

The trade-off is time. On-page changes can show effect within weeks, but competitive terms may need links, reviews and months of consistent content before rankings move.

What does this look like in practice?

A pattern in small business sites: every page titled with the business name only, service pages with no H1, and three pages all loosely targeting the same main service.

Rewriting titles around each page's topic, adding clear H1s and question-style H2s, and merging the overlapping pages into one strong service page gives search engines a much clearer picture of what each page is for.
