Yes there is. You are losing out on potential traffic if you do not have Meta tags in your website. The three key Meta tags that can be aptly used to empower your on -page SEO strategies are the Title Tag, the Keyword Tag, and the Description tag. If you can get these three tags perfectly, you could see yourself being placed right up there in the organic rankings of the major search engines even without proper link building strategy, or other time-consuming methods. However you need to be absolutely sure that you are using these tags correctly, otherwise there is a chance of your website getting penalised. The aspect which the various search engines really appreciate is a webpage that evolves continually. Hence testing and fine-tuning your tags will undoubtedly help you. Another advantage of Meta robots tag is exclusion of certain pages from the indexing conducted by the robots. It becomes difficult for search engines to correctly place a website in the absence of Meta tags.
