Anyways, SEO generally improves over time. We have to admit that it is hard to get excellent results during the first year of existence of a website.
However, we are now at the age of real-time SEO and it is possible in some cases to obtain spectacular results within a few months.

Anyway, it will all depends mainly on the competition and how far ahead they are of the keywords you are targeting.
