Adding invisible keywords to your content is also a estonia mobile database no-no. Some sites that engage in black hat SEO do this by making the text the same color as the background of the page. This means that the page may appear in search results for those invisible keywords, even though there is no visible content about them on the page. When users click on the result and think it will be related to the topic they searched for, they don’t find anything they are looking for because the keywords are invisible.
