What exactly is SEO? SEO stands for Search Engine Optimization and basically this just effects your SERPs or Search Engine Rank Positions. And if you ask what SERPs are? These are how your site is listed in search engines on certain searched Keywords. For example, if you search the word game on google right now, the first link there has the highest SERP for that keyword and the links below it decrease in number of their positions. The higher SERP you have, the better you are and more likely you will get traffic for that keyword. There many search engine placement services out there that can help you set your content so you will rank higher in search engines for your desired keywords. Some of these companies are very legit and worth trying.
Now getting some SEO help to higher your SERPs is nothing illegal. People do it all the time. You can do it too but usually these services are faster and better but they do cost. So how will you do your own SEO for your site? Easy! Just build up on backlinks. Get as much backlinks as you possibly can. One tip: Try to get backlinks from sites with the same niche or category as your own site. The more you have the better. You can also set your meta tags and contents with the keywords you want searched. Just don’t overdue it and make every other word the same keyword because it is noticeable and you can get banned from search engines like that. Good luck doing some SEO for yourself and remember if you need help, there are companies out there that can and will help you out. Good luck!
