What is On-page SEO Grader + Fix Suggestions

On-page SEO Grader + Fix Suggestions is for the moment you’ve written a page, picked a target keyword, and you still feel unsure about what to change first. Maybe the copy reads fine, but the page is not pulling in the right visits. Or a teammate asks for an “SEO check” and you don’t want to reply with vague advice.

The free On-page SEO Grader + Fix Suggestions by FlexiTools.io gives you a clear report from the content you paste on screen. In under 60 seconds, you can enter a Target keyword, paste your page HTML or text, click Grade Page, and get a score plus fix suggestions you can copy and share. What’s the one change that will matter most right now?

How to Use Our On-page SEO Grader + Fix Suggestions

  1. Type your focus term into Target keyword. If you want, add a Page URL (optional) to keep the report tied to a specific page you’re reviewing.

  2. In Paste HTML or page text, paste the page HTML or the main content text. This field is large, so you can drop in a full page section without trimming it first.

  3. Click Grade Page. The message area updates, the Score changes from a dash to a number, and the checks table fills with rows under Check, Status, and Detail.

  4. Read Fix suggestions, then use Copy Report if you want to paste the findings into a doc or ticket. If you need the output in a structured format, click Download JSON. Use Clear to wipe the fields, or Load Example to see how the report looks with sample input.

Why FlexiTools.io Offers the Best On-page SEO Grader + Fix Suggestions

It works from the text you have, even before a page is live

The tool lets you paste HTML or page text, so you can grade a draft from a doc or a staging snippet. Many graders only work if they can read a live page. Here, you can review content while it’s still being edited.

Checks are visible and explained, not buried

The results are laid out as a table with three columns: Check, Status, and Detail. That makes it easier to understand what passed, what failed, and why. When you are handing feedback to a writer, those “detail” notes save back-and-forth.

Fix suggestions are kept in one place for copy-paste work

The Fix suggestions block sits under the table and is focusable, so you can click into it and move through the text. This helps when you are pulling action items into a task list. You don’t have to rewrite the report from scratch.

Built-in actions match real review loops

The buttons reflect how people actually work: Load Example to understand the output, Clear to start fresh, Copy Report to share, and Download JSON to save the results in a consistent format. The message area and score also update using live status regions, so changes are easier to track as you run the grade again.

  • This tool: Paste content, grade it, review a score, scan checks with details, then copy or download the report.
  • Typical alternatives: Manual checklists that miss things, or tools that only work from a live URL and don’t explain the “why.”
  • Frustration avoided here: Vague feedback like “add the keyword more.” The table and fix suggestions give you concrete next steps tied to the pasted page.

A Deeper Look at On-page SEO Grading and Fix Suggestions

On-page SEO is mostly about clarity. You’re helping people and systems understand what a page is about, how it’s structured, and whether it matches the query you care about. A grader turns that broad goal into smaller checks you can act on. In this tool, you see those checks as rows in a table, each with a status and a detail note. You also get a score, which acts like a quick summary of how many checks look good.

Why the target keyword matters

The Target keyword field gives the tool a focus point. Without it, “good SEO” becomes a guessing game. With it, the report can judge whether the page content appears aligned with the term you entered. That alignment is not just repetition. It’s about whether the main topic shows up in places readers expect, and whether supporting text stays on-topic.

HTML vs page text

The tool accepts Paste HTML or page text because people review content in different states. If you paste HTML, you’re giving the tool a view that may include headings and other structure. If you paste plain text, you’re giving the tool the body copy in the form you might share with a writer. Either way, the tool grades what you provide, then explains its findings in the checks table and fix suggestions.

How to read the score without overreacting

The Score is a shortcut, not a verdict. It helps you spot when a page is far from ready or close enough to ship. The real value is in the table rows. A single failed check with a strong detail note can be more important than several minor passes.

Using the checks table like a to-do list

Each row gives you three things: what was checked, whether it passed, and a detail explaining what was found. When you’re editing a page, work from the most concrete items first. If a detail tells you something is missing, add it. If it tells you something is weak, rewrite a small section and grade again.

A simple way to stay sane is to fix one theme per run. For example, do one pass to tighten the page’s topic focus, then another pass to improve how sections are labeled and ordered. The tool supports this because you can keep the same keyword, update the pasted content, and click Grade Page again.

What “Fix suggestions” are best for

The Fix suggestions block is the bridge between “analysis” and “editing.” It’s where you pull next actions from the report without rereading the whole table. I often treat it like a checklist I can paste into a ticket, then mark items off as I update the page copy.

A quick, realistic workflow example

I’ve used graders like this when a landing page felt scattered. The target keyword was clear, but the pasted text had three different product angles and no strong through-line. After grading, the check details made it obvious the page wasn’t reinforcing the same topic in key spots. I rewrote the opening paragraph to match the keyword intent, tightened the headings, pasted the updated content, and graded again. The score moved, but more importantly, the fix suggestions shifted from “core alignment” to smaller cleanups.

Pro-Tips for Getting the Most Out of On-page SEO Grading

  • Grade the “main content” first, then the whole page. Start by pasting just the core section you want to rank. After you fix the big issues, paste a fuller version to catch stray mismatches.

  • Use Copy Report to speed up reviews with others. Paste the report into your doc or ticket so writers and editors see the same check details you saw. It keeps feedback concrete.

  • Try one close keyword variation as a second pass. Keep the page text the same, change only the target keyword, and grade again. If the report changes a lot, your page topic may be too broad.

What should I paste into “Paste HTML or page text”?
Paste either the page HTML or the main content text, depending on what you have. The text area is sized for longer content, so you can include full sections. After grading, the checks table and fix suggestions reflect what you pasted. If you paste a shorter excerpt, the report will focus on that excerpt.
What does “Page URL (optional)” do?
It lets you associate the report with a specific page you are reviewing. You can still grade the page without it. If you include a URL, it’s there for reference while you work. The grading still runs on the pasted HTML or text you provide.
Why does the score show “Score: -” at first?
The score is blank until you click Grade Page. Once grading runs, the score updates in the results area. If you clear the form, it returns to the dash. That makes it obvious whether you are looking at a fresh page or a graded report.
What is the difference between “Copy Report” and “Download JSON”?
Copy Report is for pasting the report into a message, doc, or task. Download JSON is for saving the same results in a structured file. Both are useful when you want to share findings without taking screenshots. Use whichever fits your workflow.
What does “Load Example” do?
Load Example fills the fields with sample input so you can see how the grader output looks. It’s helpful if you want to understand the checks table format before using your own page. You can then replace the example with your content and grade again. Clear removes the example content when you’re done.
