In a nutshell, you are paying for our time. More time means that we can do more things to rank your website. If your keyword is very competitive, then you are going to want to go with our Premium SEO.
We can increase your positioning for highly competitive keywords, but no agency can guarentee #1 positioning in Google. We do our best and bring a LOT of traffic to your website for your targetted keywords as well as long-tailed versions of your keywords.
If you are a plumber in New York City, you will need our Premium SEO. However, if you are in a less competitive niche, you can get away with our Extreme SEO. If you aren't sure, drop us a line on our Contact Us Page and we'll be happy to help you select a plan.
You will see a very small increase in traffic after 30 days. After 60 days, you'll start to see it all coming together. Generally speaking, it takes roughly 6 months to SAFELY rank your website. If an agency is promising you something faster, they are doing something that WILL get your website penalized by Google and you'll fall out of the search engine results altogether.
