In this course we've discussed a lot of aspects
that are important for your site's SEO. However, there's one – very important –
aspect we haven't talked about yet: optimizing your images. So, that's what we'll cover in this module. In this lesson, we'll explain
why images are important, and why it's important to optimize
your images. Let's dive right in! Whether you're a blogger,
an online shop owner, or you write articles for an online magazine
or newspaper, you've probably thought about whether
your posts or pages need images. The answer is: 'yes'.
There are three reasons for this. First of all,
images bring an article to life. If you use images with care,
they will make your texts more appealing, and they will help readers
better understand your article.

Moreover, well-chosen images
can also back up your message. Images are not only important
for your readers, they can also contribute
to your website's SEO. Firstly, since visual search
is getting increasingly important, images could turn out to provide you
with a nice bit of traffic. Secondly, images entice people
to click your post: if a visitor has to choose which site
to visit on Pinterest or Facebook, they will choose one with an image
that's compelling to them. A post without images is even less likely
to be picked up on Facebook, Twitter, and Google. So, it's definitely important to add images
to your posts and pages! Finally, images are a very important aspect
of a branding strategy. If you consistently use illustrations
and photos that fit your brand, your audience will eventually recognize
and remember your brand from simply looking at your pictures.

Once you've selected a nice
and compelling image, the next step is to optimize it
for use on your website. But why is it so important
to optimize your images? Well, first of all, it's important to optimize
your images for accessibility reasons. For example, your users may have turned
off images in their web browsers, or they could be using a screen reader
because of any visual impairments. To ensure that no information gets lost
in these situations, you should always make sure
to add an image alt attribute – also called: alt text or alt tag –
to your images. This provides your visitor
with a descriptive text if for any reason this visitor
can't see the image. We'll explain more about this later on
in this module. Secondly, image optimization
is important for SEO. As I've mentioned before, images can
improve almost any post or page – remember the saying
"a picture is worth a thousand words"? Your article becomes a lot more attractive
with images.

By optimizing your images, you provide both your users and search engines
with a textual description of the image. We'll discuss how you do this further on
in this module. For now, you need to know
that optimizing your images will not only increase accessibility but also
your chance of ranking in image search. In addition, you should make sure
your images load fast. After all, loading times are incredibly
important for UX and SEO.

The faster the site,
the easier it is to visit and index a site. Images can really slow down your site. That's why you should resize
your images and serve them
in the smallest file size possible. But loading times are also important
for conversion. According to a test by Google,
every two-second delay can drop your engagement
and affect your revenue by over 4%. If you own an online shop, chances are that you have images
on just about every page of your site. If you don't scale
and compress your images, they can slow down navigation
and make people leave your site. If you want to offer your visitors a great
experience and improve conversion, you should put some extra work
into optimizing your images. Now, let's summarize
what we've learned in this lesson. It's very important to add images
to your posts and pages, not only because images
bring an article to life, but also because they improve your SEO. However, it's not enough to just add images
– you should optimize them as well.

We've seen that image optimization
is important for accessibility, SEO and conversion reasons. That's it! In the next lesson, we'll explain how you
should prepare images for use in your article..
