# Do not remove front matter.
---
Hugo determines the _next_ and _previous_ page by sorting the current section's regular pages according to this sorting hierarchy:
Field|Precedence|Sort direction
:--|:--|:--
[`weight`]|1|descending
[`date`]|2|descending
[`linkTitle`]|3|descending
[`path`]|4|descending
[`date`]: /methods/page/date/
[`weight`]: /methods/page/weight/
[`linkTitle`]: /methods/page/linktitle/
[`path`]: /methods/page/path/
The sorted page collection used to determine the _next_ and _previous_ page is independent of other page collections, which may lead to unexpected behavior.
For example, with this content structure:
```text
content/
├── pages/
│ ├── _index.md
│ ├── page-1.md <-- front matter: weight = 10
│ ├── page-2.md <-- front matter: weight = 20
│ └── page-3.md <-- front matter: weight = 30
└── _index.md
```
And these templates:
{{< code file=layouts/_default/list.html >}}
{{ range .Pages.ByWeight }}
<h2><a href="{{ .RelPermalink }}">{{ .LinkTitle }}</a></h2>
{{ end }}
{{< /code >}}
{{< code file=layouts/_default/single.html >}}
{{ with .PrevInSection }}
<a href="{{ .RelPermalink }}">Previous</a>
{{ end }}
{{ with .NextInSection }}
<a href="{{ .RelPermalink }}">Next</a>
{{ end }}
{{< /code >}}
When you visit page-2:
- The `PrevInSection` method points to page-3
- The `NextInSection` method points to page-1
To reverse the meaning of _next_ and _previous_ you can change the sort direction in your [site configuration], or use the [`Next`] and [`Prev`] methods on a `Pages` object for more flexibility.
[site configuration]: getting-started/configuration/#configure-page
[`Next`]: /methods/pages/prev
[`Prev`]: /methods/pages/prev
## Example
Code defensively by checking for page existence:
```go-html-template
{{ with .PrevInSection }}
<a href="{{ .RelPermalink }}">Previous</a>
{{ end }}
{{ with .NextInSection }}
<a href="{{ .RelPermalink }}">Next</a>
{{ end }}
```
## Alternative
Use the [`Next`] and [`Prev`] methods on a `Pages` object for more flexibility.
