Heading tags are not necessarily an essential element for SEO, but they are another way to create a well thought out and optimized page. Heading tags are used to create the structure of a web page. There are 6 header tag sizes, from H1, the most important, to H6, the least important.
Headings should be consistent with the following content to make it easier for readers to follow.
Title tags will show search engines the hierarchy of your page’s content structure. The title tag should also include keywords. These tags may not significantly impact your keyword rankings, but they will benefit your readers and possibly search engines if used correctly. A website visitor can easily see when they land on your page, but the search engine needs more explanation, and the title tags do just that.
If you think of learning circuits in school, you will think of heading tags similarly. The h1 tag will be the heading at the top of the page. H2 tags will indicate the highlights of your page. The subtitles will be H3; the other subtitles will be H4, etc. If you have a subtitle for your post or content, the subtitle will be H2, and the main points will be H3.
When you have an image on your page, search engines don’t know what the image is; they can’t figure out what the image is. Since you can’t count on the computer to recognize the image, you need to help the search engines. It should have a simple description attached to the image. An alternate tag can help with this.
The alt tag allows you to add descriptive text to images. It is beneficial for readers who cannot download or view the image, but it is also helpful for search engines to know what is happening in the image. If you are using a screen reader, or for some reason the browser cannot display the image, or the images are disabled, the browser may show you alternative text instead.
Alt attributes provide additional context for the text on the page for search engines, which will be factored into search engine rankings. Using alt attributes will also help your images show up in image searches. The alt attribute must be a short description; it will look like spam if it is too long. It is important to use alternate tags in your navigation.
Adding an alt tag is easy and should be created for all your images. It helps you be more accessible and allows the search engine to understand your image.
