A tag is nothing more than a keyword. Those are words to find sites faster for visitors and search engines . So you give an article tags for the user. At the end of this article you can see how many tags this topic had. I show this on my blog so everybody can find quickly other articles on the blog with the same tag. So more information on the same subject. Tags make it easier for search engines, can often easily find articles with the proper tags / keywords.
A Tag Cloud s is a cloud of keywords. Common or important tags are displayed conspicuous (larger and / or bold). Usually are the tags in alphabetical order.
A tag cloud serves as an alternative form of navigation. By clicking on a tag, visitors are directed to a web page with related topics.
Heading tags H1, H2 … H6
The heading tags are mainly used to structure and shape the content of a web page . In total there are six, of which the H1 is regarded as the most important and H6 as the least important. When a web page a displayed new topic, then the subject or the name of the site is H1, the subtitle of the subject in the H2 tag placed. The size of the font changes when heading tags are used. The tags are therefore mainly the function of the visual effect.
It’s not that the search engines do not value keywords in H tags. For this reason, it is also wise to have some keywords in the heading tags to process. The website will not sudden appear high in the search engine results using this technique without any other SEO applying. This doesn’t have a big influence, but primarily serves the visitors of your website.
These tags provide the ability to use text in images. The alt text can then act as agent in case the image is not displayed on the website.
The purpose of meta tags is to inform web crawlers about your page. They existed before search engines, but today, they primarily used in terms of search engine optimization (SEO). Using them may help web crawlers more easily index your pages in search engines, but, not all web crawlers or robots pay attention to these tags anymore. A meta tag is a line of HTML coding that contains metadata about a webpage.
You might have the following heading for your webpage:
<TITLE>What is a tag</TITLE>
<META name =“description” content=”This is all about Meta Tags”>
