Web Accessibility Basics For Blog Content

Accessibility in blog content isn't a specialist concern you can hand off to a developer — most of what determines whether a blog post is usable by someone with a visual, motor, auditory, or cognitive disability happens at the writing and formatting level, in decisions any content creator makes directly. Here's what actually matters, without needing to become a web accessibility expert to get the fundamentals right.

Why this matters beyond compliance

It's easy to file accessibility under "legal risk" or "nice to have," but the practical reality is that accessible content is simply better content for everyone. Descriptive headings help every reader scan a page, not just screen reader users. Good color contrast helps someone reading on their phone in bright sunlight, not just someone with low vision. Captioned or transcribed video helps someone in a quiet office as much as it helps someone who's deaf. Accessibility improvements very rarely make content worse for non-disabled readers — they usually make it clearer for everyone.

Alt text for images

Alt text is a written description of an image that screen readers announce to users who can't see the image. It's one of the most common accessibility gaps in blog content, and it's entirely within a writer's control.

• Describe what's actually relevant about the image, not everything visible in it. If it's a screenshot of a specific setting in an app, describe the setting and its state, not the entire browser chrome around it.
• Don't start with "image of" or "picture of" — screen readers already announce that it's an image, so that phrasing is redundant.
• Purely decorative images (a stylistic divider, a background pattern with no informational content) should generally have empty alt text (alt="") so screen readers skip over them rather than announcing something meaningless.
• Don't stuff alt text with keywords for SEO purposes. Alt text's primary job is accessibility; treating it purely as an SEO field produces descriptions that are useless to the people who actually rely on them.

Heading structure

• Use headings in a logical hierarchical order — H1 for the title, H2 for main sections, H3 for subsections within those, without skipping levels just because a smaller size "looks right" visually. Screen reader users often navigate a page by jumping between headings, and a broken hierarchy makes that navigation confusing or misleading.
• Don't use heading tags purely for visual styling (making text bold and large without it actually being a heading) — this misleads anyone navigating by heading structure, since it tells them a section exists where there isn't one.
• Write headings that describe the content that follows them, so someone scanning by headings alone (a common pattern for both accessibility and general readability) gets an accurate map of the page.

Color and contrast

• Don't rely on color alone to convey information. If you're marking something as "important" with red text, also say it's important, or use an icon or label alongside the color — colorblind readers may not perceive the distinction you intended.
• Check text-to-background contrast, especially for stylized quote blocks, callout boxes, or any custom-colored text in your posts. Low-contrast text (light gray on white, for instance) is difficult for many readers, not only those with low vision.
• Links should be visually distinguishable from surrounding text by more than color alone — underlining or a distinct visual treatment helps readers who can't easily distinguish color differences identify what's clickable.

Link text

• Avoid vague link text like "click here" or "read more" repeated throughout a page. Screen reader users often pull up a list of all links on a page out of context, and a page full of "click here" links tells them nothing about where each one goes.
• Make link text describe the destination: "read our full guide to keyword research" instead of "click here" pointing at the same destination.

Video and audio content

• Provide captions for video content. This helps deaf and hard-of-hearing users, but also anyone watching without sound, which is a large share of social and mobile video views regardless of disability.
• Provide a transcript for audio-only content like podcasts embedded in a post — this also has the side benefit of giving search engines indexable text content from what would otherwise be an unreadable media file.
• Avoid auto-playing audio or video with sound, which can be disorienting for users with cognitive or sensory processing differences, and is broadly considered poor practice regardless of accessibility concerns.

Readable, plain language

• Write in plain, direct language where the topic allows it. This benefits readers with cognitive disabilities, readers who aren't reading in their first language, and honestly, most readers in general — clarity is rarely a loss.
• Break up long blocks of text with headings, short paragraphs, and lists. Dense unbroken text is harder to process for many readers with cognitive or attention-related disabilities, and it's harder to scan for everyone else too.
• Define jargon and acronyms on first use if the piece is aimed at a general audience.

Keyboard and structural basics for your platform

Most of these live at the theme or platform level rather than in individual post content, but they're worth knowing about if you have any control over your site's setup:

• Interactive elements (buttons, forms, navigation) should be operable by keyboard alone, not just mouse or touch — some users can't use a mouse or touchscreen due to motor disabilities.
• Forms (like newsletter signups or comment boxes) should have properly associated labels, not just placeholder text that disappears once someone starts typing.

A practical baseline checklist for every post

• Every meaningful image has descriptive alt text; purely decorative images have empty alt text.
• Headings are used in proper hierarchical order and describe what follows them.
• No information is conveyed by color alone.
• Link text describes its destination rather than reading "click here."
• Video has captions; audio-only content has a transcript.
• Text has reasonable contrast against its background, especially in styled callouts or quote blocks.

The bottom line

Accessibility isn't a separate task bolted onto publishing — it's a set of habits that fit naturally into writing and formatting a post well in the first place. None of the items above require special tools or technical skill beyond attention and habit, and most of them make the content genuinely better for readers who don't have any disability at all, which is as good a reason as any to build them into your process by default.
