You are looking for an image of Half Dome at Yosemite. You use a search engine like Google or Bing or even Pinterest. You key “Half Dome image” for your search and up pops a search result with hundreds, if not thousands, of images for you to view. You may not be aware that you just asked your search engine to go through its database to find websites that have the key words Half Dome and image embedded then display them in the search results. Search engines employ web crawlers, sometimes referred to as bots, which continuously move through the internet hitting web site after web site finding and cataloging key words and linking those keywords to the site so that search results are quickly displayed. So, as you can see, having some well-crafted keywords in your website is very important.
So, how do you craft keywords to be useful? You need to make them specific. This morning, a search on Yosemite yielded 52.6 million results, Half Dome yielded 5.7 million results and half dome images yielded 7.5 million results. When I narrowed my search to Half Dome images sunset, it whittled the list to 270,000 results. If you are posting a sunset image of Half Dome, those words should be used as keywords. If you are posting a watercolor, you need to say that too. If it is location specific, it also helps to tag your image with a location. Another important consideration is phrasing, Here you try to guess what someone might enter as a search request and create keywords that are phrases; something like “Half Dome images”. So you might use this set of keywords: Half Dome, Half Dome images, Half Dome sunset, Half Dome sunset images, sunset images. The list needs to be accurate and meaningful.
Are keywords going to bring you to the top of the search results? No! What industry experts call Search Engine Optimization or SEO, is a mysterious technology that is closely guarded by each search provider. Many people claim to be experts at SEO but what I have read is that no one has really cracked the code. Still, keywords are still important. They are the method that gets you on the search result list. After getting your keywords in order, find some big name celebrity like Jennifer Lopez to recommend your site to her followers so you can trend and get to the top of the results.
Good luck with keywords.
