README 文档

README

Enterprise-grade SEO Tools for CodeIgniter 4 — a complete port and extension of the battle-tested ecosystem, rebuilt from the ground up for CI4 with schema validation, AI-bot governance, multi-tenancy, and ≥95% test coverage.

Requirements

Requirement	Version
PHP	`^8.1`
CodeIgniter	`^4.4`

Installation

composer require cmmishra9/ci4-seotools

Publish the config file and view partials to your app:

php spark seotools:publish

This copies app/Config/SEOTools.php and app/Views/seotools/ into your project. The config is fully annotated — read it before you deploy.

Quick start

In your <head> layout (e.g. app/Views/layouts/default.php):

<?= seo_generate() ?>

In a controller:

seo()->setTitle('Home')
     ->setDescription('Welcome to Acme Corp.')
     ->setCanonical('https://acme.com/');

seo_og()->setSiteName('Acme Corp')->setType('website');
seo_twitter()->setSite('@acmecorp')->setType('summary_large_image');

Components

SEOMeta

Generates <title>, meta description, keywords, robots, canonical, pagination links, hreflang alternates, and webmaster verification tags.

use RcsCodes\SEOTools\Meta\SEOMeta;

$meta = new SEOMeta();
$meta->setTitle('Article Title')
     ->setTitleDefault('My Site')       // produces: Article Title | My Site
     ->setTitleSeparator(' | ')
     ->setDescription('A concise description under 160 chars.')
     ->setKeywords(['php', 'codeigniter', 'seo'])
     ->setRobots('index, follow')
     ->setCanonical('https://example.com/article')
     ->setPrev('https://example.com/page/1')
     ->setNext('https://example.com/page/3')
     ->addAlternateLanguage('fr', 'https://fr.example.com/article')
     ->addMeta('theme-color', '#ff5500');

echo $meta->generate();

Config-driven defaults — set meta.defaults in app/Config/SEOTools.php to pre-populate title, description, robots, and canonical across every request.

OpenGraph

Generates all og:* meta property tags with full namespace support.

seo_og()
    ->setTitle('Article Title')
    ->setDescription('Open Graph description.')
    ->setUrl('https://example.com/article')
    ->setType('article')
    ->setSiteName('My Site')
    ->setLocale('en_US')
    ->addImage('https://example.com/og.jpg', [
        'width'  => '1200',
        'height' => '630',
        'alt'    => 'Hero image',
    ])
    ->setArticle([
        'published_time' => '2024-06-01T12:00:00Z',
        'author'         => 'https://example.com/author/jane',
        'section'        => 'Technology',
        'tag'            => ['PHP', 'SEO'],
    ]);

Supported namespaces: article, book, profile, music, video, place.

TwitterCard

seo_twitter()
    ->setType('summary_large_image')
    ->setSite('@mysite')
    ->setCreator('@author')
    ->setTitle('Article Title')
    ->setDescription('Card description.')
    ->setImage('https://example.com/card.jpg')
    ->setImageAlt('Card image description');

JsonLd / JsonLdMulti

// Single block
seo_jsonld()
    ->setType('Article')
    ->setTitle('Article Title')
    ->setDescription('Article description.')
    ->setUrl('https://example.com/article')
    ->addImage('https://example.com/img.jpg')
    ->addValue('author', ['@type' => 'Person', 'name' => 'Jane Doe']);

// Multiple blocks on one page
seo_jsonld_multi()
    ->setType('WebPage')->setTitle('Home');

seo_jsonld_multi()
    ->newJsonLd()
    ->setType('Organization')
    ->addValue('name', 'Acme Corp');

Schema types

use RcsCodes\SEOTools\Schema\Types\Article;
use RcsCodes\SEOTools\Schema\Types\BreadcrumbList;
use RcsCodes\SEOTools\Schema\SchemaGraph;

// Standalone
$article = new Article();
$article->setHeadline('My Post')
        ->setAuthor('Jane Doe')
        ->setDatePublished('2024-06-01')
        ->setImage('https://example.com/img.jpg')
        ->setPublisher(['@type' => 'Organization', 'name' => 'Acme']);

echo $article->generate();

// Combining multiple types in one @graph block (recommended)
$graph = new SchemaGraph();
$graph->add($article)
      ->add((new BreadcrumbList)
          ->addItem('Home', 'https://example.com/')
          ->addItem('Blog', 'https://example.com/blog/')
          ->addItem('My Post', 'https://example.com/blog/my-post'));

echo $graph->generate();

SchemaGraph

Combines multiple schema types into a single @graph block — the Google-recommended pattern for pages with more than one schema type.

seo_schema()
    ->add($article)
    ->add($breadcrumb)
    ->add($faqPage);

echo seo_schema()->generate();

Sitemap

$sitemap = seo_sitemap();
$sitemap->addUrl('https://example.com/', 'daily', '1.0')

        ->addUrl('https://example.com/gallery', images: [
            ['loc' => 'https://example.com/photo.jpg', 'caption' => 'Gallery photo'],
        ])
        ->addUrl('https://example.com/video', video: [
            'thumbnail_loc' => 'https://example.com/thumb.jpg',
            'title'         => 'Demo video',
            'description'   => 'Watch the demo.',
            'duration'      => 180,
        ]);

return $sitemap->toResponse(); // sets Content-Type: application/xml

SitemapIndex

use RcsCodes\SEOTools\Technical\SitemapIndex;

$index = new SitemapIndex();
$index->addSitemap('https://example.com/sitemap-posts.xml', '2024-06-01')
      ->addSitemap('https://example.com/sitemap-pages.xml');

return $index->toResponse();

RobotsTxt

seo_robots()
    ->allow('*', '/')
    ->disallow('*', '/admin/')
    ->disallow('*', '/private/')
    ->crawlDelay('Googlebot', 1)
    ->blockAllAiTraining()      // Disallow: / for all known training bots
    ->addSitemap('https://example.com/sitemap.xml');

return seo_robots()->toResponse();

HreflangManager

seo_hreflang()
    ->addLanguage('en', 'https://example.com/')
    ->addLanguage('fr', 'https://fr.example.com/')
    ->addLanguage('de', 'https://de.example.com/')
    ->setDefault('https://example.com/');

echo seo_hreflang()->generate();

RedirectHelper

use RcsCodes\SEOTools\Technical\RedirectHelper;

// Register at boot time (e.g. in a service provider or BaseController)
RedirectHelper::register('/old-slug', '/new-slug');
RedirectHelper::register('/deleted-page', null, 410); // Gone

// In a route or filter
if (RedirectHelper::has($path)) {
    $entry = RedirectHelper::get($path);
    if ($entry['code'] === 410) {
        return RedirectHelper::gone();
    }
    return redirect()->to($entry['to'])->withCode($entry['code']);
}

    ->preconnect('https://fonts.googleapis.com')
    ->dnsPrefetch('https://cdn.example.com')
    ->preload('/fonts/inter.woff2', 'font', ['crossorigin' => 'anonymous'])
    ->prefetch('/js/chart.js');

echo seo_hints()->generate();

AiBotManager

Fine-grained AI-crawler policy engine that outputs robots.txt rules, X-Robots-Tag headers, and meta robot content.

use RcsCodes\SEOTools\Enterprise\AiBotManager;

$mgr = new AiBotManager();

// Named presets
$mgr->applyPreset('retrieval');   // allow crawling, block training datasets
$mgr->applyPreset('restrictive'); // block all AI bots
$mgr->applyPreset('permissive');  // allow everything

// Granular control
$mgr->allowRetrieval()->blockTraining();

// Per-bot override
$mgr->setBot('GPTBot', ['Allow: /public/', 'Disallow: /']);

// Apply to a robots.txt builder
foreach ($mgr->toRobotsTxtRules() as $bot => $rules) {
    foreach ($rules as $line) {
        // e.g. 'Disallow: /'
    }
}

// Apply as HTTP header
$mgr->applyHeaders(service('response'));

// Get meta robots content string
$content = $mgr->toMetaContent(); // e.g. "noai, noimageai"

EEATMarkup

Structured data for E-E-A-T signals (Experience, Expertise, Authoritativeness, Trustworthiness).

seo_eeat()
    ->setAuthor('Jane Doe', 'https://jane.com')
    ->setAuthorJobTitle('Senior Software Engineer')

echo seo_eeat()->generateOrganizationSchema();

SEOMiddleware

Automatically injects a <link rel="canonical"> tag into HTML responses that don't already have one. Register in app/Config/Filters.php:

public array $globals = [
    'after' => [
        \RcsCodes\SEOTools\Enterprise\SEOMiddleware::class,
    ],
];

Enable/disable via enterprise.middleware_auto_inject in your config.

MultiTenantManager

Per-domain config overrides for SaaS platforms.

// app/Config/SEOTools.php
public array $tenants = [
    'brand-a.com' => [
        'meta'      => ['defaults' => ['title' => 'Brand A', 'separator' => ' — ']],
        'opengraph' => ['defaults' => ['site_name' => 'Brand A']],
    ],
    '*.brand-b.com' => [   // wildcard subdomain
        'meta' => ['defaults' => ['title' => 'Brand B']],

Configuration reference

After running php spark seotools:publish, your app/Config/SEOTools.php exposes:

// Meta tag defaults applied to every request
public array $meta = [

        'description' => null,
        'keywords'    => [],
        'robots'      => 'index, follow',

        'site_name' => null,
        'images'    => [],
    ],

        'ClaudeBot' => 'retrieve',
        'CCBot'     => 'disallow',
    ],
];

// Multi-tenant overrides (keyed by domain or *.wildcard)
