In the contemporary times, a website has become the most valuable tool to generate business. However, just designing and launching a site is not enough. The entire corporate domain has turned exclusively competent these days. Thus, the business entities jostle for higher SERP (Search Engine Result Page) ranking to ensure better visibility for themselves on the internet. Therefore, the aspects of SEO (Search Engine Optimization) and web designing are perfectly complimentary to each other. SEO – as it is widely known – deals with the aspect of augmenting visibility of websites across the virtual World Wide Web.

There are some important HTML tags for SEO that are widely used by these professionals. Search Engines have become smarter these days. As such, procedures that facilitate SERP rankings are more logical and human-like these days. The overall process is also considerably transparent.
In this backdrop, it is crucial to discuss in brief some of the most significant HTML tags that are highly popular in SEO.
Prominent HTML tags
Title tag
Example: <title>”title goes here…” </title>

• Choosing a suitable title tag for a website is most essential.
• As such, Google will represent the website by the title that will come here, on its SERP listing.
• Preferably, it must be of 68 characters in length

Meta tag
<meta name=”description goes here….” content=” ” />

<meta name=”keywords” content=”KWD1, KWD2,……..” />

• Search Engine retrieves the content or the character string that is placed within the Meta description tag and displays the same as its description of the website on its respective SERP listing.
• Length of meta description differs from Search Engine to Search Engine. Therefore, to be on the safer side, it is better not to exceed the meta description length beyond 160 characters counting blank spaces.
• Keywords used in the meta are prone to draw attention of visitors, thus, there is always the probability of it bringing in more traffic.
• Each meta tag should be well-descriptive, relevant and unique for each page of a website.

Canonical tag
Example: <link rel=”canonical” href=”” />

• Before getting into this topic it is crucial to know that duplicate content is a severe issue with major Search Engines and websites containing such contents are heavily penalized.
• A canonical page is a much common practice in the SEO industry. It is in fact the preferred version of a number of pages having highly identical content
• It often happens that a website contains pages that apart from minor variations have much in common. In this backdrop, an SEO expert declares a particular URL, from the set, as Canonical. With this declaration, one easily overcomes the chances of letting the Search Engine crawler consider that the entire site contains duplicate content.

A href tag
Example: <a href=”” >Home</a>

• Anchor tags are used to jump to specific locations of a webpage or a website altogether.
• The first part of the tag, defined with ‘a href’ contains the URL or the path to the targeted location.
• The second part, as defined outside the angular brackets, is a string which has actually been hyperlinked. Clicking on the mentioned string takes a user to the specific location mentioned in the URL.

ALT tag
Example: <img src=”image.gif” alt=”image-title/keyword”>

• An Alt tag is an invisible description of images.
• These are strictly meant for visually challenged users.
• The alternate text describes the supporting image and as such, it is read out aloud on a screen reader.
• Adding Alt tag allows an author to include images to a webpage.

H1 and H2 tags
Example: <h1>This is main heading </h1>

<h2>This is sub heading 1</h2>
• H1 and H2 tags are basically used to declare headings.
• As such, HTML supports 6 different headings, starting from H1 to H6.
• However, from SEO aspect the first two that define main heading and main sub-heading respectively are important.
• These tags are supported by all major browsers including Mozilla Firefox, Google Chrome and Internet Explorer.

As such, there are plenty of tags provided by HTML. However, as mentioned earlier, it is not that every tag is crucial and significant from the SEO aspect.
