What are H1, H2 & so on in web design?

Think of these tags as the headings you would put in an outline of an essay that you are planning to write. They are important because search engines see these as excerpts or highlights of the page as a whole and these tags will help reinforce the meaning of the page. Without them, a search engine is left to draw its own conclusions with no clues.

h1 and h2 both are used for heading.

difference

<h1> text 1 </h1>

out put:
[SIZE=6] text 1

[SIZE=2]<h2> text 2 </h2>

output:

[SIZE=5]text 2

[SIZE=2]I think now difference between h1 and h2 is clear
the difference only is size.

The H tags are heading tags that format your text into headings. H1 is the most prominent (largest), H2 the second, and so forth. You need to mind the content of each heading tag, it's probably a good idea. What he is essentially saying is that the search engines look to these tags for relevant meaning for SEO. Don't fill them with junk, essentially.

thanks guys for this. it is very helpful for me.

Right, h series tags are all used for heading text. Especially the H1 tag, it is really useful for SEO.

Hey, there, a lot of webpage developers use the H1/H2/H3 tags for formatting. Nothing wrong with this but if you talk about SEO, these tags are very important. These tags support the overall theme placed in the title tag.

Imagine for a moment that your webpage is an outline and the topic of your outline is the “title” of your page (the one in your title tag) and the H1 tags are your first level topics under your title. Now H2 tags are sub topics that support whatever is in H1.

Meta tags are often part of the coding of a website, although they are being found less and less these days. Meta tags are elements of the web page language HTML or XHTML that provide metadata, data or information for the search engines about that webpage. Meta tags can be used to detail the page description, keywords and other data not specified in the head elements of the page.

thank you very much
