During my web site development process i use my own php framework EzgFw which has seo friendly url usage feature (url routing). When i complete and deliver a web site project it has nice page urls which is better for search engines and seo. EzgFw framework has some seo friendly features like hierarchical page title generation and including page title in url. You can see an example of these within this web site. Besides that i can provide extra features on demand so that you can enter meta description and keywords for each page of your web site by using the custom administration panel of your web site.
