The overall goal of Search Engine Optimization (SEO) is to improve the reputation of your website on the internet.
If anyone promises you page one ranking on Google just moon walk out of the room because they're either gaming the system (something Google will punish you for) or they're not telling the truth.
SEO is usually done by carefully crafting your content, page titles, and page URLs (official page names) to ensure your site is particularly attractive to the search-bots used by organizations like Google.
In addition it this, acquiring links from high authority websites, like universities and well recognized brands tells search engines that your website is important to them. All of this work is referred to as optimization.
The URL of a website and placing the URL on other websites is also important for search engine optimization. For example, websites should use names that are as closely related to their service or product as possible. For example, a website that sells pens would not want to use a URL that includes the use of the word “shoes” or “boxes” in the title. Going forward, placing the URL on other websites will also help optimize the website because it gets people aware and curious if they constantly see a website they have never heard of on one of their frequently visited websites.
