The SEO table shown below is very similar to the periodic table of elements. It consists of some elements, which are toxic and others which are beneficial. Those good elements help us rank high on the SERP (Search Engine Result Page), while the toxic ones would get you penalized.

The proper use of the elements like keywords, content, metadata, quality links etc. help towards achieving a higher rank on the search engine.
