Optimising SEO and Accessibility means you are effectively influencing factors such as:
Website development is a formidable wedlock between web users and search engines.
So how does SEO and website accessibility crossover:
For SEO purposes, page title tags allow search engines to understand the relevancy of your page with the initial part of the title having the most important keywords and phrases. The keywords should be made use of in the most natural and user-friendly manner.
Page title tags display in search engines results and the browser tab area of websites but are hidden on actual web pages.
We searched for Huffington Post on Google; as you can see the title tags sets the tone and relevancy of a web page.
Title tags should ideally between 50-60 characters with spacing to meet Google, Bing (Yahoo!), and W3C guidelines. Any more characters will truncate into dots. Character limits are subject to change.
On the actual Huffington Post website, you can view the same title in the browser tab, where the arrow is pointing above.
When using assistive technology such as VoiceOver or JAWS (screen readers) for people who may have visual disabilities, the title tag will read aloud whatever is specified. This is why your website should have different titles for each page.
Please note, this will display if website owners integrate the title and meta tags on their website. If you don’t add specific text you want your web users to see then Google will generate content from your web page automatically in the title if they deem it suitable.
Also, when you share your website page on social media, the page title will display.
In the HTML code, the title tag is shown below for Huffington Post's Homepage. If we added this as text on here, the HTML would have picked up and hidden it as mentioned earlier, therefore, we had to display this as an image.
So it's good practice to make each page title relevant, appealing and click-worthy as possible as they are rich snippet ads of your website.
The use of headings and sub-headings with relevant keywords flowing seamlessly improves your SEO rankings.
Headings also break down chunks of content and enables the user to easily scan your pages, which is great for all types of users. Headings and subheadings structure's the content as the user goes through the page. It's better than having one page full of just text as this immediately puts the user off reading further.
Headings are particularly great for website accessibility too, as people with visual impairment who are using assistive technology can tab through the headings and select which content they wish to be read out.
H1 should be used once per page, subsequently, H2, H3, H4, and so on can be used more than once depending on the hierarchy of the content.
All links should be meaningful when it comes to SEO and web accessibility.
Links in your content, linking to other pages on your website are known as anchor text in SEO terms.
Do not use ‘click here’ or ‘find out more’ to describe a link as it does not assist the disabled user where the link text alone will navigate to - it has to be meaningful on its own as the screen readers will read out the link text. They can tab through just links in content too.
Generic links like ‘find out more’ will not help search engines either to understand the importance of the anchor text. So when linking to another page, specify exactly where the link will go to with 2-3 relevant keywords.
For example purposes, the anchor text link is underlined in the example shown.
Do not overuse anchor texts and overstuff with keywords, as it will be counted as spam. If the links are relevant, flows well and has high usability than its fine.
Alt tags describe's what the image represents. It's short for alternative tags.
This is great for people using assistive technology, as it will read what the image is about if implemented.
For SEO purposes, if you explain the image as well as put relevant keywords as closely related to the image, search engines will count this part of their algorithm and the image will be indexed too.
Also, when the Internet is not working properly sometimes the image won’t load but the alternative text will display instead. Same applies when the image is missing or the image file name is incorrect.
In some browsers, when you hover over an image, the alt tag will pop up.
This HTML code example includes the image file name, the size of the image and the alt tag at the end:
In WordPress, alt tags can be easily updated in the media library.
Alt tags should be integrated for all your images to describe their meaning unless it’s a decorative image, which is no use to the user so you can leave the text area empty i.e. alt=""
Ensure your web page URLs are SEO-friendly by using the most important and meaningful keywords that are relevant to the page itself.
Also, use hyphens to separate words in file names and not underscores because search engines do not recognise underscores as word separators.
E.g. our marketing services page, we‘ve named it: www.iadcontrol.com/marketing-services
Here’s a bad practice page file name that will hinder Google ranking your pages. The URL alone does not tell web users or search engines what the page is about: page_seven_564
Organising information and implementing content in a structure that's comprehensible, and searchable is critical to SEO. Without good user experience, no amount of optimisation will help your website’s rankings.
In addition, making use of breadcrumb trail is another way to show the users where they are located in relation to your website, particularly if your website has deep routed pages. This is sufficient to aid the user in navigating your website and improves the User Experience (UX).
On most websites, the menu tab is highlighted, this is a quick visual aid to indicate the user's location as well.
If you have quite a large website, then it is always handy to have a dedicated sitemap page to list all the content links of your website in a hierarchical manner. The sitemap makes it easy for users to access information effectively as a flat structure and makes every page reachable.
People using assistive technology are likely to use the sitemap page as the main source for navigating through websites quickly to find what they are searching for.
Having the latest and compliant HTML 5 code means that your website can be read by the widest possible range of browsers, devices and are less likely to break your website page. This helps all types users and won’t disrupt screen readers as they go through the pages.
On WordPress or pre-set template websites, it is rather challenging to keep the code complaint within the semantic HTML formatting so try to keep it clean where you can for each page. Do not use any styling elements hard-coded within the HTML - have this in the actual CSS file.
Complying with W3C Markup Validator is said to be potentially about 4% of the SEO algorithm. It may be a small percentage but every little helps to climb up the search listings and aid website accessibility.
That's all for now...
