t depends on your knowledge of seo, i can do a much better job of seo on a static or custom made cms than word press , because WordPress you have to abide by alot of plugins aand code bloat on the website. People say word press is seo friendly this is not true , google doesnt give preference to a cms be it drupal or whatever, the reason people say this is because of things like yoast which can teach people very quickly alot about seo they never knew before , but to a experienced seo even yoast has flaws and a lack of flexibility to fully customise the seo of your website.
