# Free SEO checker for your whole website.

> Arcline is a free SEO checker that reads your whole website, up to 200 public pages, instead of one page at a time. It scores your site out of 100 across thirteen areas, including readiness for AI answers, and turns the findings into a plain-English to-do list with exact steps. The Free plan covers one website. You prove the website is yours first, so it only checks sites you own.

## What the free SEO checker looks at

Most free SEO checkers look at one page and give you a short list. Arcline reads your sitemap, follows your links and reads up to 200 public pages, politely and within your robots.txt rules. It then turns what it found into thirteen scores, each with the reasons behind the number.

| Score | The question it answers |
| --- | --- |
| Technical health | Is your site free of broken things that confuse Google? |
| Easy to explore | Can Google find and walk through all your pages? |
| Allowed in Google | Are your pages allowed to show up in search results? |
| Speed | How quickly do your pages open for a visitor? |
| Page basics | Do pages have clear titles, descriptions and one main heading? |
| Links between pages | Can visitors and Google hop from one of your pages to the next? |
| Quality of your writing | Is your text clear and useful, or thin and repeated? |
| Proof you're real | Are there signs that real people stand behind the site? |
| Visitor trust | Do you have a safe connection, policies and contact details? |
| Hidden labels for Google | Is the structured data that describes each page present and correct? |
| Ready for AI answers | How easy is it for an AI assistant to quote your answers? |
| AI assistants can find you | Are ChatGPT and similar assistants allowed in? |
| One clear business name | Is your business name written the same way everywhere? |

The scores combine into one health score out of 100 with a plain verdict, from “Excellent” to “Needs attention”.

## How to run it in three steps

1. **Add your website.** Type its address. That is the only information the setup needs to begin.
2. **Prove it is yours.** Paste one line of code, add a DNS record or upload a small text file. This is why Arcline only checks websites you own, and it keeps your results private.
3. **Read the results.** The scan takes a few minutes and shows its progress. You then see your scores and your to-do list, and a fresh check runs by itself every week on Free and every 5 hours on Premium.

It works as an online SEO checker: nothing is installed on your website for the scan. The [setup guide](https://arcline.celira.space/docs) shows all three ways to prove ownership.

## What you get after the check

- **An overall health score out of 100,** with a plain verdict and a card for each of the thirteen areas.
- **A to-do list in plain language,** sorted into what Arcline can fix, what needs your OK and what only you can do, with exact steps and a Copy text button for your developer.
- **Speed checks** on your key pages, using Google's speed test when it is available.
- **A history chart** and a list of what changed since the last scan.
- **Re-checks by themselves,** every week on Free and every 5 hours on Premium, so you can see whether a fix worked. You can also press “Check my site now”: once a day on Free, every 5 minutes on Premium.

Every part is explained in [Features](https://arcline.celira.space/features).

## What is free and what is Premium

| What you get | Free | Premium |
| --- | --- | --- |
| Websites | 1 | 3 included, more for an extra fee |
| Full scan, thirteen scores and the to-do list | Yes | Yes |
| Automatic re-scans | Every week | Every 5 hours |
| Fixes through GitHub, WordPress or Ghost that wait for your OK | Up to 10 a month | Unlimited |
| Autopilot: safe fixes made for you, checked live | No | Yes |
| AI-answer tracking | One snapshot of 5 checks | 25 questions per website, weekly, with history |
| Content studio, competitor watch and change alerts | No | Yes |

Premium costs $9 (₹699 in India) a month or $86.40 (₹6,710 in India) a year, and you can cancel any time. The check itself stays free, with no card needed. See [pricing](https://arcline.celira.space/pricing).

## What an SEO checker cannot tell you

- It cannot promise rankings or traffic. No honest SEO checker can.
- It checks the links between your own pages. It does not list the backlinks other websites give you.
- It does not show where you rank on Google or how many people click. That data comes from Google Search Console, which Arcline does not connect to today.
- Some speed numbers are estimates until Google's full test has run, and Arcline labels them as estimates.
- It reads public pages. Pages behind a login are not checked.

> **A score is a guide, not a ranking.** Fix the biggest items first, then let the next check show whether it worked.

## What to do with your results

1. Start with the weakest score and open its card.
2. Do the quick wins first: missing titles and descriptions, a missing main heading and broken links.
3. Let Arcline prepare the fixes it can, and approve the ones you are happy with.
4. Give changes a few weeks before judging. [How long SEO takes](https://arcline.celira.space/faq/how-long-does-seo-take) explains why.
5. If your site is missing from Google altogether, read [why a website is not showing on Google](https://arcline.celira.space/faq/website-not-showing-on-google).

Arcline works as a free SEO audit tool for one website. For a fuller picture of what an audit covers, see [what an SEO audit is](https://arcline.celira.space/faq/seo-audit).

## Common questions

**Is the SEO checker really free?**

Yes. The Free plan costs nothing and covers one website: the full scan, the scores, the to-do list and a weekly automatic re-scan. Premium adds the autopilot, faster re-scans and extra tools. No card is needed to start.

**How is this different from a one-page SEO checker?**

A one-page checker looks at a single address. Arcline is a website SEO checker: it reads up to 200 pages, scores the site as a whole, spots site-wide problems such as broken links and sitemap issues, and checks again by itself, every week on Free and every 5 hours on Premium, so you can see progress.

**Do I need to install anything?**

No. You add your address and prove you own the site with one line of code, a DNS record or a small text file. Nothing is installed on your website for the scan itself.

**Can I check a competitor's website?**

No. Arcline only scans websites you have proved you own, which also keeps your own results private. To study a competitor, read their pages the way a visitor would and compare them with yours.

**How often does it check my site again?**

Automatically: every week on Free and every 5 hours on Premium. You can also press Check my site now, once a day on Free and every 5 minutes on Premium. Scores only change once the pages have been read again.
