SeoCore bundle is an Symfony2 implementation of seotracker/seo-core library. This is a common way to deal with websites, search engines and scrappers.
- Websites
Website is an object representation of a real website. A website MUST have a HTML content.
A website object can return useful data for SEO like:
- Website title
- Website metadata & rich contents
- Website keywords occurrences and proportions (Not implemented)
- Website location url
See WebsiteInterface of seo-core library for more information about it.
- SearchEngines
SearchEngine is an object representation of a real search engine. A search engine SHOULD USE a scrapper to get information from internet network.
A search engine can return useful datas for SEO like:
- All websites for a needle (aka a "keyword")
- Website position in the concerned search engine for a needle
- All backlinks for a website in this search engine
See SearchEngineInterface of seo-core for more information about it.
- Scrappers
A scrapper is an object used to get HTML from internet network.
As this object have only 1 job to do, the only method to implement is get
which accept at least 1 argument: an url location.
See ScrapperInterface and implementations in Adapter\Scrapper folders of seo-core library.
- Crawlers
A crawler is an object used to query and manipulate HTML DOM.
Seo-core offers an interface and his Symfony2-Component based implementation.
See CrawlerInterface and implementation in Adapter\Crawler folders of seo-core library.

namespace SeoTracker\Bundle\DemoBundle\Controller;

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;
class DefaultController extends Controller
{
/**
* @Route("/seo/{url}")
* @Template()
*/
public function indexAction($url)
{
$googleEngine = $this->get('seo_tracker.search_engine');
$website = $googleEngine->getWebsite($url);
// position of website in Google
$position = $googleEngine->getPosition('seo tools online platform', $website); // 1
// title of website
$title = $website->getTitle(); // 'SeoTracker : A SEO tools suite'
// metas of website
$metas = $googleEngine->getMetas();
// ['description' => 'Seo Tracker est une plateforme de suivi et d'optimisation [..]']
// microdatas of website
$microDatas = $googleEngine->getMicroDatas();
/**
* [0 =>
* 'type' =>
* [0 => 'http://www.schema.org/CreativeWork']
* ,
* 'properties' => [...]]
* ],
* [ 1 => [..] ]
**/
// backlinks of website location in search engine
$backlinks = $googleEngine->getBacklinks($website);
/**

* 1 => 'http://otherwebsite.backlink'
* ]
**/
return [];
