Frequently asked questions

What is this page compare tool and how do I compare two web pages side by side?

The page compare tool fetches two URLs at once and lays out their SEO data, headings, word count, keywords and links side by side, then highlights every difference. Just paste two page URLs into the A and B boxes and click Compare to see a side-by-side comparison of the two pages.

How can I compare SEO meta tags between two URLs?

This page compare tool extracts and compares the title, meta description, robots, canonical, viewport and charset of both pages, with length guidance so you can spot truncated titles or missing descriptions. It is built specifically to compare SEO tags between two web pages, such as a competitor's page versus your own.

Can I compare two pages to see which words and content changed?

Yes. Open the optional word-by-word text diff to see exactly which visible words were added or removed between page A and page B, along with an overall text similarity percentage. This makes it easy to compare two versions of a page and find content changes.

How do I compare a staging page with the live production page?

Put the staging URL in box A and the live production URL in box B, then compare. The page compare tool shows the text similarity score, every differing metric, and a highlighted diff of the content, so you can verify a staging vs production page before you publish.

Does this tool work on JavaScript pages and React or Next.js SPAs?

Yes. Keep the Render JS option on and the page compare tool renders client-side pages with headless Chromium before comparing, so React, Next.js, Vue and other single-page apps are compared with their fully rendered content instead of an empty shell.

How can I compare word count, headings and internal vs external links between two pages?

The tool counts visible words and characters on each page, lists the full H1-H6 heading outline, and classifies every link as internal or external, flagging links that appear on both pages. It is a quick way to compare word count, heading structure and link profiles across two URLs.

Is this online page comparison tool free, and does it support other languages?

Yes, this is a free online tool to compare two pages with no sign-up needed for the core comparison. It uses Unicode segmentation, so word counts and the text diff stay accurate for any language, including Hindi, Arabic and Hebrew (RTL), Chinese, Japanese, Korean and Thai.

Can I compare my page against a competitor's page?

Yes — put your URL in box A and the competitor's in box B, then Compare. You'll see their titles, descriptions, headings, word counts, keywords and links side by side, which makes it easy to spot where a higher-ranking competitor's page is more thorough than yours.

Is anything I compare stored or shared?

No. The tool only fetches the two public pages to compare them and show the diff — nothing you enter is saved on our servers, and the pages themselves are never modified. The core comparison needs no sign-up.
