The purpose of any website is to drive traffic. And greater portion of visitors is coming from search engines. In order to increase the traffic we need to communicate with the search engines which increases their rankings which in turn drives more traffic.
One of the best ways to engage audience is by using HTML tags. These are some of the most important elements you need for your website.
Title The <title> tag defines the title of the document. The title must be text-only, and it is shown in the browser's title bar, in the page's tab and displays a title for the page in search-engine results.
Meta The viewport is the user's visible area of a web page. It varies with the device - it will be smaller on a mobile phone than on a computer screen. Define keywords for search engines. Define a description of your web page. Open graph supports things like descriptions and images as well. It simply gives you customization options if your webpage is shared on social media.
Heading Heading tags are often used to break up the content to make it easier to read. In reality, about 55% of visitors will only spend 15 seconds at most skimming your content. They make it easier for these people to find what they’re looking for quickly.
Img alt The alt attribute of this tag tells search engines the picture is about cooking pork with onions. Without the ALT tag, search engines don’t know what the image is about. And this could reduce exposure during image searches.
Anchor with nofollow attribute "nofollow" attribute doesn't help the linked websites to increase their SEO rankings.
