Optimize Alt Tags to Improve Increase Search
Alt tags or alternative tags are the meta tags
that are alternatives for images on your pages. These on-page SEO
factors have several different functions and are useful for various
purposes. One such usage is to increase search engine ranking as well
as search engine visibility of your webpages. But, let's see what
exactly they are.
Alternative tags are descriptive phrases that are attached to the
images in the source code of your webpages. They could be visible to
your readers or invisible. Some people prefer to use text-only browsers
or opt to turn off their images for some reasons like having higher
internet speed. In such cases, they would see and read such
descriptions to know what type of images are used at the page.
How Search Engines Could Care about Alt Tags
Alt tags could both be on-page SEO boosters and
off-page SEO boosters. As you know search engines could read text and
links. They won't be able to rank images by their beauty, relevancy,
etc. So, to help them understand and rank images at our pages, we
should provide some textual data to help them realize what the image is
about. It's not only about helping search engines. We actually help
Search Engine Findability
When we add alternative tags to our images, at the end of the day it's
our images that are optimized and it's our pages that are found by
search engines. What we gain will be search engine ranking and search
engine visibility. This benefit could be merely for the images to be
found or to help our textual content to be found.
Search Engine Visibility in Image Search
Image search is a function several search engines
offer these days. In order to be found and ranked highly for our
images, an advisable practice will be to add alt tags to our images. Of
course, we should mention our page's keyword that's related to that
particular image in one way or another. Then, it will both help human
visitors and search engines.
Search Engine Ranking for the Keywords
According to some SEO experts, in Google local listings, chances are
some sites rank well that have only used their keywords in the
alternative tags of their images. The reason is obvious! As search
engines aren't able to discover the relevancy of images to the textual
content of a page, they have to read their alt tags. When you provide
this, you'll see the organic SEO results.
Another way to help increase search engine ranking of a page through
alt tags is when the image with alt tags is linked to another page. In
such cases, these tags will function as off-page SEO factors, like
anchor text in the links. So, they help the ranking of a website in two
1) Alt tags help internal linking structure of a website if they are
used in linked images within a site.
2) Such tags help increase search engine ranking of a page for the
keywords used in the inbound links images.
Final Word about Alt Tags
As alternative tags are easy to manipulate and use for spamming search
engines, some SEO experts believe that they won't have much effect on
the search engine ranking of a website and search engines don't
consider them as very important factors in gaining organic SEO results.

ranking, we'd better make use of them all in the right way so that all
