You'll set the default titles, descriptions and images used when someone finds or shares your pages. SEO means search engine optimization: helping search engines describe your pages. Site-wide defaults provide a starting point; individual pages can have their own title, description and social image.

## Set the defaults

1. Open **General Settings** → **SEO**.
2. Enter **Website Name** and choose **Title Separator**. Together with **Title Template**, these control the default search title.

3. Review **Title Template**. The chips stand for changing values, such as the current page's title. Place your cursor where you want a value, select **Insert variable**, then choose **Page title**, **Separator** or **Website name**. You can also type ordinary words and move or remove chips in the editor.

4. Write **Default Meta Description** and choose **Default Social Media Share Image**. Use a description that explains the site and an image that represents it well.
5. Review **Preview**, then select **Save**.

| Field                                | What it does                                                | Tip                                                                                      |
| ------------------------------------ | ----------------------------------------------------------- | ---------------------------------------------------------------------------------------- |
| **Website Name**                     | Supplies the site name used by title chips.                 | Use the name visitors recognize.                                                         |
| **Title Separator**                  | Supplies the punctuation between title parts.               | Choose one style for the site.                                                           |
| **Title Template**                   | Combines chips and text to make default page titles.        | Page title, separator and website name gives each page a distinct title with your brand. |
| **Default Meta Description**         | Supplies a description when a page has no individual one.   | The editor suggests a length; make the wording useful rather than filling space.         |
| **Default Social Media Share Image** | Supplies a sharing image when a page has no individual one. | Check the crop in several previews.                                                      |

For example, the page-title chip, separator chip and website-name chip can produce "Contact | Acme" on your contact page and "About | Acme" on your about page.

## Check social previews

Use the **Google**, **Facebook**, **X**, **LinkedIn**, **Discord** and **Slack** preview tabs to see how the title, description and image may appear. These are previews; each service controls its final display and may shorten text.

Individual pages have their own [SEO fields](https://docs.systhema.app/nl/next/editor-guide/pages/page-seo.md). A page's own values take priority over defaults. Posts may also have an **SEO** tab, depending on your site.

## Check afterwards

Check an important public page and its individual SEO preview. Search results do not update immediately after you save: search engines need to revisit the page. Social services can also keep an older preview. Ask your agency if a shared link keeps showing an old image after publication.
