We have to start this article by telling you, our reader, that the process of Google SEO is much faster than say, Yahoo or Bing SEO. Google is, in our opinion, the most efficient and powerful search engine because of the amount of data that they analyze. They not only keep track of all the links from all the sites they crawl, but analyze the data of every page, apply PageRank to each one, and derive a ranking. Even though Google is this efficient, the process for a normal site, meaning any site other than Twitter, or Facebook, takes time. While Google can process SEO changes on a page as fast as two weeks, good results begin to happen in 2 to 3 months, and great results in 2 to 3 years.
This is not to say that you can't get your site ranked in the top 10 for a keyword that has 1,000 monthly searches, it can be done in 1 month, but depending on the topic of the keyword, competition will become your biggest obstacle. For example, if you are trying to become the king for keywords in the Search Engine Optimization arena, you will find that the competition is fierce, much more so than say an Auto Radiator Repair Company would. This is simple math; more people in the SEO field are qualified and know about optimization than would owners of auto repair shops.
Because Google Optimization, while being the fastest to see results, still is a long-term affair, don't feel over anxious to re-optimize your site before giving enough time for your previous efforts to take effect. The truth of the matter is that after about a month, you will get a good idea of what is working; you have to find a good site that provides a ranking tool, so that you can check your site's performance for specific keywords. There are many out there and all are free, so don't fret.
Our best advice is to take the time to write good, solid and relevant content in relationship to your other page elements like Meta tags, page title, website topic, and link titles. Give your efforts time to bloom before making changes. The biggest problem we see is that inexperienced SEO efforts are NOT given enough time to grow, and are cut short before full bloom can be achieved. Sorry for the plant analogies, but it will help illustrate our point best.
