I just curious to is there something between php and seo? Is website written in php easier to optimize? Why is that? Any advantages of php except it is open source?
Yes PHP is just a programming language, but probably you have heard that PHP is good for SEO because PHP programmers have done a lot of work to make the website easy SEO optimized with PHP and CMS like Wordpress under PHP has perfect SEO plugins which lets you fly in SEO
PHP can be used to simplify SEO techniques, for example I often store all my titles, meta descriptions, content in a database and use a single template in PHP to generate all my pages. Also all web pages are open source, just right click view source.
Yep, search engines don't see the php, only the results. It can be easier to seo a medium/large site if it's built using php (or other server-side coding options), because one change can affect multiple pages (a double edged sword, obviously).
i know that seo is base on the url. not by the programming language. if you are using framework. the uri is control by the php. if not you can control the uri via .htaccess
Any language can be used to make an SEO-friendly page and any language can be used to make an SEO-hostile page. You're asking what the relationship is between English and truth, or Spanish and accuracy. One has absolutely nothing to do with the other.
