(From effectiveranking4u@gmail.com) Hello, 

I'm a web traffic optimizer, and I noticed that as I used my SEO reporting tools, there's a lot of room for improvement for your website to rank higher on search engine results. This means that you have a great potential to be easily found by potential clients searching for products/services online if the issues on your website get fixed. 

Google has a way of "crawling" your site and looking for certain keywords that they index to what people online are searching. The more optimized your site is, the higher ranking you get! This leads to more online credibility, thus more sales! With my skills and knowledge, I guarantee that can put your website ahead of your competitors. 

If you're interested in hearing more, I can give you a free consultation for you to be more informed. Don't worry about my fees since my target is to accommodate small businesses at a cheap price. Let me know what time is best for you to be contacted, and I'll gladly reach out via a phone
