Keywords are very important because they will determine the success of your website. Keywords form an important aspect of on-page SEO and you must include your keywords in the meta title, descriptions, body content and H1 to H6 Headings.
I am going to take your starting keywords and use them as a basis for extending my research. I will use a variety of popular SEO tools to research the popularity and value of your target keywords and come up with proposals.
The way it works is you will have to send me your keywords/description of who, what, where and when you want to target. I will then come up with long tail keywords that you can incorporate into your SEO strategy.
Getting the keywords right is key for your success.
