I read today an email of a SEO blogger who said that his completly new niche websites became much harder to rank nowadays than a few months ago. He said, that it is not possible anymore to rank a website fast (even with targeting low competition KWs), which is only a few weeks online. Instead, it became much more a slow and steady process. Is that really the case? Would it maybe make more sense to create several website first with about 5 articles and after 2 months put more content and backlinks on them instead creating 1 website, concentrating on it and when its finished starting the next one?
