When creating a good website that you want to be able to monetise, you need to be careful with certain things that you have to avoid in order to get a good ranking in Google, to avoid the infamous “Google dance” or the possibility of being blacklisted from their search results at some point. There are “White Hat” and “Black Hat” techniques that webmasters use to get traffic, but if you want a stable business you must stick to White Hat only. This simply means that all the methods you implement on your website for popularity will be legal and that you will play by the rules!
One of the most important things that you need to remember when you are dealing with your images is to make sure that their name matches the content of the image itself. Some people are using illegal tactics to get visitors by renaming some of their images to the hottest keyword trends and search results. This leads to people looking for something but being directed to an image or article that has nothing to do with the content they needed. If Google catches you doing this, they will ban your site from the search and you will never have a change to get enough traffic without the help of the most important engine in the world.
Just try to make sure that your images always match the content, this will also help your SEO efforts and give you more exposure when people search for something that you have to offer. The best way to get to the top of the search results in your keywords and niche is to do create quality content and to never attempt to mislead people into your website. If you do this, you will start to see good results sooner than you might think. Just be consistent with your efforts.
