5. NoFollow Attributes
We use links to refer to external and internal sources in our content. Links contribute immensely to our SEO and also affect the perception of others about your content. While they can make it look like a reliable piece backed up by relevant sources, they can also make it look like a piece of garbage with little or no relevance.
As such, you must pay attention to your sources and the effects of your links. Links are tagged by default as "follow links," meaning you cast a vote of confidence on your source. But you can also place a link and still do the reverse. You can add a no-follow instruction or attribute, meaning you are instructing search engines not to follow the link.
In conclusion, do not neglect the tiny bits that make up the big picture. While backlinks and other SEO tactics may look highly relevant, some meta tags are a must-have in your content.
