Using long tail keywords is now a waste of time. This is because of Google RankBrain. RankBrain is an AI (artificial intelligence), so to this new algorithm, all related long tail keywords are the same. It is now pointless to use such long tail keywords. What I would recommend, instead, is use Medium Tail Keywords along with LSI Keywords. This is the new way of keyword research! 😉 Your content is the meat and potatoes of your website. With all of the Google Panda updates, it is extremely important that your content is unique and relevant. If you have multiple pages with the same content (or if you have your content on other people’s websites), you will run the risk of getting penalized by Google and your search rankings will suffer.
Stop whatever you're doing and ask yourself this simple question: "Do I need a website?" If your response was anything other than "yes," you need to think again. It doesn't matter if you're the head of a multinational corporation who employs thousands of people or a local mom-and-pop shop from around the way, you need a website to help potential customers find you online. If you have a business, failure to establish an online home is a failure to grow.
After you choose a website builder and a theme, take some time to learn how to use and customize these tools. Once you feel comfortable, start making changes. Some easy changes to start with are to add your name, logo, and contact details. Then, change the text font and color, add image galleries, background pictures, banners, and other site enhancements.
