README

An all-in-one SEO module for SilverStripe.

Note: Version 1.0.4 of this repository replaces version 1.0.3 of vulcandigital/silverstripe-seo.

Features

• SEO Health Analysis in the Page Editor
• Automatic Facebook OpenGraph meta-tag generation (can override)
• Automatic Twitter meta-tag generation (can override)
  • Also adds a TwitterAccountName field to SilverStripe\Security\Member which is used for the creator tag. The creator is recorded when a new page is created and their Twitter account name will be used for the meta tag

Example Meta Tags Output

<link rel="canonical" href="http://atmtanks.local/"/>
<meta property="og:title" content="Home"/>

Requirements

See composer.json for details.

Installation

composer require quinninteractive/silverstripe-seo

Getting Started

The necessary extensions are automatically applied after installation of this module, and a dev/build.

Writing Your Own Analysis

Health analyses have been abstracted to give developers the ability to create their own analysis checks.

To do this, you simply need to create a new class that extends QuinnInteractive\Seo\Analysis\Analysis.

As an example, let's create a new analysis that checks to see if Hello World! is the title of the current page.

First create the following file:

mysite\code\Analysis\HelloWorldTitleAnalysis.php

<?php

namespace Vendor\Project\Analysis;

use QuinnInteractive\Seo\Analysis\Analysis;

class HelloWorldTitleAnalysis extends Analysis
{
    const FAILED = 0;
    const SUCCESS = 1;

    public function run()
    {
        if (!strstr($this->getPage()->Title, 'Hello World!')) {
            return static::FAILED;
        }

        return static::SUCCESS;
    }

    public function responses()
    {
        return [
            static::FAILED  => ['The string "Hello World!" does not appear in the page title', 'danger'],
            static::SUCCESS => ['Hoorah!!! "Hello World!" appears in the page title', 'success'],
        ];
    }
}

Then dev/build. You will immediately see this new analysis running in the CMS under the "SEO Health Analysis" accordion when editing any page, then change the title to include "Hello World" and you will notice the indicator will display success.

One thing to keep in mind is that the analysis always has access to the \Page object that it is running against via $this->getPage(), so your responses can also be dynamic.

If you have created an analysis and think it would be beneficial as an addition to this module then we urge you to submit a Pull Request and you will receive full credit for your work. See CONTRIBUTING.md.

Explained: run()

You must override this method as this is where you will perform all your checks, and then return with an integer respective of the keys you define in responses(). It's a good idea to use constants that represent those integers for readability

Explained: responses()

All analyses must override the responses() method to provide response messages and the response level (which is used for the indicator).

run() should return an integer that matches a key in the array that responses() returns, for example if run() were to return 1, then using the above example the message displayed would be Hoorah!!! "Hello World!" appears in the page title with an indicator level of success

The available indicator levels are: default, danger, warning, success which are grey, red, orange and green respectively.

You can optionally prevent certain levels from displaying in the content analysis tab. The following added to the above example would cause it to only display an entry if the indicator level is not of value success:

private static $hidden_levels = [
    'success'
];

Configuration Options

enable_creator_tag

By default, this module adds an extension to \SilverStripe\Security\Member that adds a single field named TwitterAccountName. If this is set, when this particular user creates a page, the twitter:creator meta tag will be generated with the Member's account name

You can disable this via YAML:

QuinnInteractive\Seo\Extensions\PageSeoExtension:
    enable_creator_tag: false

Length of meta description

The module has 2 configuration options pertaining to the length of the meta description. The sample YAML below demonstrates them with their default values. You don't have to make such a file unless you want different values from the defaults.

QuinnInteractive\Seo\Analysis\MetaDescAnalysis:
  meta_desc_target_length: 160
  meta_desc_too_long_threshold: 320

Other Options

Other options can be found in the private static variables in the following files. They can be overridden in YAML in the usual way.

• PageHealthExtension.php
• PageSeoExtension.php
• SiteConfigSettingsExtension.php

Assumptions

This module assumes that you make use of the default Content field provided by \Page. If a specific page does not then you can specify one or multiple fields that contain your content.

They should be ordered in the correct order that they appear for the end user

In your \Page subclass you would have:

public function seoContentFields()
{
    return [
        'Content',
        'MyBlock.Title',
        'MyBlock.Content',
        'BottomTitle',
        'BottomContent',
    ];
}

In your \Page subclass you could add an updateCollateContentFields to provide custom content that is not possible with seoContentFields:

public function updateCollateContentFields($content) {
    // Content is an array of strings with content in the order in which they appear to the user
    $content[] = 'This is example content';
    return $content;
}

Roadmap (subject to change)

• Finish implementing internationalisation to this module and its analyses
• More content analyses
• Given the ability to practically have content coming from anywhere on a SilverStripe page, the seoContentFields method was introduced to better improve content analysis by collating all content fields into a single string, this supports dot notation for has_one relationships, but may not (or does not) support has_many and many_many relationships at this time. Ideally moving forward we will want to use the DOM parser (partially implemented) and rely on this instead.
• Finding community support to help improve and better this module for all SilverStripe users
