You do not need a tool to check on-page SEO problems. A focused 10-minute manual check covers the issues that matter most and is easy to repeat before publishing. A focused 10-minute manual check covers the issues that matter most and is easy to repeat before publishing. This guide gives you a checklist you can run on any page, with or without the SEO Optimizer.

Before you start

Open the page in a browser and view its source (or use your CMS preview). Have a notepad ready. You are checking whether the page is easy to discover, understand and use — not chasing a score.

Minute 1: Indexability

• Is the page meant to rank? If yes, it must not be blocked.
• Check the <head> for <meta name="robots" content="noindex">. If present and unintended, remove it.
• Check robots.txt for a Disallow rule covering this path.
• Confirm the page returns 200, not 404 or a redirect.

Minute 2: Title

• Does the <title> describe the page in plain language?
• Is it roughly 50–60 characters? (Not a hard rule, but a useful target.)
• Does it include the main topic naturally?
• Is it unique across the site?

Minute 3: Meta description

• Is there a meta description?
• Does it summarize the page and invite a click?
• Is it roughly 150–160 characters?
• Is it unique?

Minute 4: Headings

• Is there one clear <h1> that matches the page topic?
• Do <h2> and <h3> break the content into scannable sections?
• Are headings descriptive, not clever?

Minute 5: URL and canonical

• Is the URL short, lowercase and readable?
• Does it use hyphens between words?
• Is there a self-referencing <link rel="canonical">?
• Does the URL match the canonical form (https, trailing slash, no parameters)?

Minute 6: Content

• Does the first paragraph answer the main question?
• Is the content original and useful, not filler?
• Are there clear examples, steps or evidence?
• Is the reading level appropriate for the audience?

Minute 7: Links

• Do internal links use descriptive anchor text (not "click here")?
• Are there broken links? Spot-check a few.
• Does the page link to at least two related pages on your site?
• Are external links to credible sources where claims need support?

Minute 8: Images

• Do images have concise, descriptive alt text?
• Are file names readable (not IMG_1234.jpg)?
• Are images appropriately sized (not 4000px wide for a thumbnail)?

Minute 9: Snippet preview

• Search the target query and look at the top results. Does your title and description look competitive?
• Does your page answer the query better than what ranks?

Minute 10: Mobile and speed

• Open the page on a phone (or resize the browser to 375px wide). Is it readable and usable?
• Does the page load without obvious delays?
• Are there layout shifts as it loads?

Printable one-page checklist

Print this list and work through it on any page before you publish. It is the same ten checks in a compact form:

• Indexability: no noindex, no blocking robots.txt rule, page returns 200.
• Title: describes the page, roughly 50–60 characters, unique on the site.
• Meta description: exists, summarizes the page, roughly 150–160 characters, unique.
• Headings: one clear H1 matching the topic, H2s and H3s breaking the page into sections.
• URL and canonical: short, lowercase, hyphenated, self-referencing canonical, matches the canonical form.
• Content: first paragraph answers the main question, original and useful, with examples and evidence.
• Links: descriptive anchor text, no broken links, at least two internal links, external links to credible sources.
• Images: concise alt text, readable file names, appropriately sized.
• Snippet preview: search the target query and check that your title and description look competitive.
• Mobile and speed: readable at 375px wide, no obvious delays, no layout shifts.

After the check

Write down the top three issues and fix them before publishing. Re-run the check after editing. If you want an automated version of this review, paste the page into the SEO Optimizer for a scored report with prioritized findings.

When to use a tool instead

A manual check catches the obvious problems. Use a tool when you need to:

• Check dozens of pages at once.
• Verify technical signals like redirects, headers and structured data.
• Compare a page against a target keyword.
• Track improvement over time.

The SEO Optimizer covers all of these for a single page.
