I would like to know can I do SEO for any website, which is developed on any platform?Can anyone justify on this?
Yes, you can do SEO for any kind of website developed on any platform. You can use various CMS like Wordpress, Joomla, Drupal, Magento or any Language like PHP, ASP, JSP, Python, Ruby on Rails etc to develop your website. Any search engine doesn't bother about which kind of platform you are using to develop your website. They just consider you valid HTML and the Content on your website. Your code should be able to produce neat clean HTML on browser with less load time and your website should contain Search Engine friendly URL's with relevant content on your topics with less keyword stuffing. I will prefer to use Wordpress to develop your website as it is quite easy to use and more search engine friendly. I ahve various website based on the Wordpress and they are performing quite well in search engine rankings.
Yes seo can be done no matter which platform of development it is on. Some of the famous cms like joomla, wordpress are very good to do seo because they are search engine friendly. I also agreed to shamittomar comment.
of course you can, actually search engine doesn't matter about which kind of platform you are using to develop your website. They just consider valid HTML and the Content.
