Heading tags are not necessarily the key element to SEO but they are another way to create a well-rounded optimized page. Heading tags are used to give a webpage structure. There are 6 sizes of heading tags ranging from H1, which is the most important, to H6, which is the least important. Heading tags typically make the text inside them larger than the normal text on the page, which helps to separate the content into relevant sections and make it easier for the user to read and scan the page for the information they are looking for.
The headings should be relevant to the content that follows to make it easier for the readers to follow and navigate the page. The heading tag should also include keywords. These tags might not make a huge impact in your keyword rankings but when used properly they will benefit your readers and possibly the search engines. The heading tags will show the search engines the hierarchy of structure of your page's content. A site visitor can usually see the easily when they land on your page, but a search engine needs more explanation and the heading tags do that. If you think back to learning outlines in school in you think of heading tags in a similar way. An H1 tag will be the title at the top of the page. The main points on your page will be designated with H2 tags. Sub-points would be H3, further sub-points would be H4 etc. If you have a sub-title for your post or content then the sub-title would be H2 and the main points would be H3. The H1 tag should only be used once per page and if the H2 tag is used as a sub-title that should only are used once as well.
When you have an image on your page search engines don't know what the image represents, they can't detect what an image is. Since you can't count on the computer to recognize an image you should help the search engines with it. You should have a simple description included with the image. An alt tag can help with this. Alt stands for alternative text. An alt tag allows you to add descriptive text to your images. If you're using a screen reader or if for some reason a browser isn't able to show the image, or the images are shut off, the browser can instead show you the alternative text. This is not only helpful for readers who can't load or see the image but it is helpful for the search engines to know what is going on in an image.
Alt attributes provide further context for the text on the page for search engines, which will be factored into your search engine rankings. Use of alt attributes will also help your images come up in image searches which can help to drive more traffic and conversions to your website. The alt attribute should be a short description, if it's too long it will seem like spam. It is extremely important to use alt tags in your navigation. If you have a site visitor who can't see images, failure to use alt tags in the navigation could make your site navigable to them.
Adding an alt tag is easy to do and should be created for all of your images. It helps your accessibility and it can help the search engine understand your image.
