accessibility

Accessibility means that something can be used, obtained, approached, entered or reached. Two meanings applicable to the Internet can be derived from this. Firstly, the provision of Internet access to people with disabilities or the elderly as barrier-free as possible, and secondly, the accessibility and readability of a website for a crawler.

Accessibility in terms of absence of barriers

Today, the Internet is widely viewed as a free space designed to be accessible to large numbers of people. Accessibility plays an important role in this context. As part of W3C, the Web Accessibility Initiative (WAI) advocates that the Web should be usable by as many people as possible. The WAI has been striving for this since 1997. To facilitate access for users with physical restrictions to information on the Internet, the WAI has developed several guidelines since 1999:

Web Content Accessibility Guidelines (WCAG): These include information on web programming standards and also cover content, technology, and design.
Authoring Tools Accessibility Guidelines (ATAG): In this case, special conditions apply to the tools used to create web pages.
User Agent Accessibility Guidelines (UAAG): These guidelines define the conditions that browsers or media players must meet.
Web Accessibility Initiative, Accessible Rich Internet Applications (WAI-ARIA): This policy is intended to ensure that, through metadata and special features, blind people can also use web applications and widgets.

The W3C has published a list of for webmasters.

Accessibility and SEO

Accessibility is also an important concept for SEOs, as it relates to creating websites in such a way that the content and technical structure can be easily accessed by search engine spiders. Therefore, it can be concluded that a perfect accessibility is the result of a perfect optimization of a page.

The following are important factors in providing maximum accessibility and readability for a web crawler:

Clean font

A clear site structure like with header tags.
A clear structure of the content, for example, with paragraphs, bold or italics.
The provision of relevant content in text and image or moving images.
There is no content hidden by JavaScript.
No complicated flash animations.
There are no broken links.
The judicious use of meta-information such as title or description to clearly identify the content.
Optimization limits

Especially for SEOs, the temptation is great to over-optimize a website. Keyword accumulation (stuffing) is a significant factor. Therefore, before engaging in any accessibility optimization, any SEO should ask themselves whether these improvements will ultimately create additional benefits for users.

Last words

Normally, flash animations are perfect for those users who are looking for vector graphics that do not lose image quality when modified. Similarly, it should be noted that it occupies a few bytes of storage and is not heavy, which represents a great benefit when running it.
What allows us to create Flash animation?

Flash animation is like a box of surprises, because it allows us to play with our imagination. In other words, with it we can create both multimedia and interactive content, being a mix between programming and graphic components.
