Understanding Search Engine Optimization (SEO)
Whenever a user conducts an online search from sites like Google and Bing, the search results you see are the ones most relevant to whatever question is being asked. If you search for a Thai restaurant, the results of your search will include Thai restaurants near your location.
The goal of SEO is to maximize the potential for a web page to appear as one of the results. The closer a web page shows up near the top spot, also known as rank, the more likely it will be clicked.
So it is important to help the search engine understand what your image is about so it knows where to place it in the search results. Plus, search engines don’t see the content of an image. In order for it to "see" the image, i.e content, colors, style, medium, etc, it looks at the information available on the page, such as a description or title. It may also look at other pages that your artwork page is linked to, such as your resume page.
To take advantage of SEO, you should provide as many details about you and your work as possible. The more unique details you can add, the more likely you and your work will be discovered.
