README

Seo-core library was extracted from Seo-Tracker platform. 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 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 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 folder

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 folder.

<?php
use SeoTracker\SeoCore\Adapter\Crawler\SymfonyCrawler;
use SeoTracker\SeoCore\Adapter\Scrapper\CurlScrapper;
use SeoTracker\SeoCore\Model\GoogleFranceEngine;

$crawler   = new SymfonyCrawler();
$scrapper = new CurlScrapper();
$googleEngine = new GoogleFranceEngine($scrapper, $crawler);

$website = $googleEngine->getWebsite('http://seo-tracker.net');

// 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' => [...]]
 * ],
