My webpages have 2 version with and without index.php in url. Google indexing the web pages having index.php in url. Although I've coded canonical tag targeting without index.php url still google indexing the urls having index.php. Should I do SEO for index,php urls or without index.php.
You can add also redirect in htaccess - after a while google should place on top your root domain - and you should seo for it, not some subpage (even if it's main).
I wonder (just a wild guess) if adding a trailing slash (somesite.com/) will eventually re-index it without index.php. How do you have it in your base href or cannonical tag with or without "/"? Whatever you do, don't end up having duplicate content. You know something like: somesite.com/ somesite.com/index.php www.somesite.com/ www.somesite.com/index.php So, I wouldn't do a SEO for index.php or for the name with the www if I were you. Just pick somesite.com/ as your target URL and optimize that.
In your know indexing is the process of adding webpages into Google search. Depending upon which meta tag you used (index or NO-index), Google will crawl and index your pages.
