Good Search Engine Optimization (SEO) is priceless. It helps your website come right on top in a search engine when your potential customer is searching for you. It’s a no-brainer – A business that is present in the top few results will get exponentially higher returns.
Search Engines such as Google keep on changing their algorithms with an objective to deliver better search results to their customers. For example, with the Penguin and Panda updates, they decided having too many advertisements above the fold, and having exact match domains was now a bad thing to do.
So essentially, no agency can guarantee a #1 rank on Google.
If getting the first rank so difficult ? Not really. Lets start with a systematic Keyword Research for SEO and follow it up by getting someone to do Content Writing for SEO for your website, and getting fresh content regularly.
