|
|
|
|
Add automatically generated Search Engine Optimization to your Website
|
|
|
|
## Install
|
|
|
|
1. Add this code to your `<head></head>` structure (e.g in `layouts/_default/baseof.html`):
|
|
|
|
```html
|
|
<!-- Site Indexing toggled by key value of `private` in Page/Post Settings -->
|
|
<meta name="robots" content=
|
|
{{- if or (.Params.private) (in (string .Permalink) "404.html") (in (string .Permalink) "404.php") -}}
|
|
"noindex, nofollow"
|
|
{{- else -}}
|
|
"index, follow"
|
|
{{ end }} />
|
|
|
|
<!-- Meta Keywords/Tags for Users to search for in Search Engines -->
|
|
<meta name="keywords" content="
|
|
{{- with .Params.tags }}
|
|
{{- range . -}}
|
|
{{ with $.Site.GetPage (printf "/%s/%s" "tags" . ) }}
|
|
{{- .Title -}},
|
|
{{- end }}
|
|
{{- end }}
|
|
{{- else -}}
|
|
Tutorials, Tips, Linux, Bash, Docker
|
|
{{- end }}" />
|
|
|
|
<!-- Canonical URLs -->
|
|
<link rel="canonical" href="{{ .Permalink }}" />
|
|
<link rel="alternate" href="{{ .Permalink }}" hreflang="{{ .Site.LanguageCode }}" />
|
|
|
|
<!-- Links to RSS Feed -->
|
|
{{ range .AlternativeOutputFormats -}}
|
|
{{ printf `<link rel="%s" type="%s" href="%s" title="%s" />` .Rel .MediaType.Type .Permalink $.Site.Title | safeHTML }}
|
|
{{ end -}}
|
|
```
|
|
|
|
2. Add the default key/value `private = true` to `/archetypes/default.md`
|
|
|
|
```yaml
|
|
---
|
|
title: "{{ replace .Name "-" " " | title }}"
|
|
date: {{ .Date }}
|
|
draft: true
|
|
|
|
## Add this key with value 'false' for indexing by search engines enabled by default
|
|
private: false
|
|
---
|
|
```
|
|
|
|
## Usage
|
|
|
|
Add these keys and values to any page's settings:
|
|
|
|
|
|
```toml
|
|
+++
|
|
...
|
|
tags = ["fruit", "apple", "health"] # Fitting keywords that describe your post/page
|
|
private = true # true if you want it private/unlisted
|
