Strikethrough is a small formatting choice with a surprising number of use cases. Ecommerce stores use it to show a discounted price. Bloggers use it to mark corrections without deleting the original claim. Product teams use it on changelogs and roadmaps. Because the text remains visible while signalling that it is no longer valid, people reasonably wonder whether search engines still read it, still count it, and whether relying on it could distort how a page is understood. So does using strikethrough affect your SEO? Mostly no, but there are specific situations where it matters more than you would expect.

How AAMAX.CO Gets On-Page Details Right

Small formatting decisions accumulate into how clearly a page communicates, and clarity is what search engines reward. AAMAX.CO is a full service digital marketing company offering Web Development, Digital Marketing and SEO Services worldwide, and our on-page work covers exactly these details: semantic markup, price presentation, structured data accuracy and content freshness signals. Our SEO services include full template and content audits that catch the markup problems most teams never notice until rankings slip. If you want an expert eye on how your pages are actually rendered and interpreted, hire AAMAX.CO and we will review the whole picture.

What Strikethrough Means in HTML

There are three ways struck-through text typically appears, and they are not equivalent. The <del> element means content has been deleted from the document, and it is semantically meaningful. The <s> element means content is no longer accurate or relevant, which is a weaker statement about validity. A CSS declaration such as text-decoration: line-through is purely visual and carries no semantic meaning at all.

Search engines read all three as text that exists in the document. The words are crawled, indexed, and considered as part of the page content. Strikethrough does not remove text from the index, and it does not exclude it from relevance calculations in any reliable way. If you struck through a keyword hoping it would stop counting, that is not what happens.

Does It Reduce the Weight of the Text?

There is reasonable logic behind assuming that semantically deleted content might be discounted. Search engines are good at understanding document structure, and content marked as removed is arguably less representative of the page's current meaning. It is plausible that heavily struck-through passages receive less weight, particularly with <del>.

But this is not something to build a strategy around. Nobody has published a reliable signal that strikethrough is treated as a downweighting instruction, and behaviour may vary between crawlers and AI answer systems. Treat struck text as fully indexable content that happens to be flagged as outdated, and make your decisions on that basis.

Where It Genuinely Helps

Corrections and transparency are the strongest case. When you update an article and want readers to see what changed, striking the outdated claim and adding the correction next to it is honest and useful. Readers trust content that shows its revisions, and demonstrable accuracy supports the credibility signals that matter in competitive topics.

Comparison and pricing contexts are the second case. Showing an original price struck through beside a sale price is a universally understood convention that improves conversion. Because it clarifies rather than confuses, it is a positive for user experience.

Progress and status displays are the third. Completed checklist items, shipped roadmap features and resolved issues all read naturally with strikethrough, and the visual pattern communicates state faster than prose.

Where It Causes Real Problems

The first risk is structured data mismatch. If your page visually strikes an old price but your Product schema still reports that struck price as the current offer, you are sending contradictory information. Rich results can display the wrong figure, and persistent mismatches between visible content and markup can cost you rich result eligibility altogether. Always ensure the schema price matches the price a user would actually pay.

The second risk is accessibility. Strikethrough conveys meaning entirely through visual styling, and screen readers do not announce it by default. A user relying on assistive technology may hear an outdated claim or a pre-discount price as if it were current. Where the distinction matters, add explicit text such as "previous price" in a visually hidden span, or use ARIA labelling to make the status explicit.

The third risk is content bloat. Long articles that accumulate years of struck-through paragraphs become confusing to read and dilute the page's topical focus. At some point, corrections should be summarised in a brief update note and the outdated body text removed entirely.

The fourth risk is keyword games. Striking through a keyword-stuffed block, or using strikethrough to keep old terms on the page for search engines while hiding their relevance from readers, is a manipulative pattern. It is unlikely to help and it looks deliberate.

Practical Rules to Follow

Use <del> when content has genuinely been removed, and <s> when it is simply no longer accurate. Reserve pure CSS line-through for decorative or purely visual cases. Keep struck content short and purposeful rather than letting it pile up. Always pair a struck price with correct structured data. Add non-visual cues so the meaning survives for screen reader users. When an article has been substantially rewritten, prefer a dated update summary over a document full of crossed-out sentences.

Consistency across templates matters too. Ecommerce sites in particular should handle sale price presentation in one shared component, so the markup, schema and accessibility treatment are identical everywhere rather than reinvented on each template.

Conclusion

Using strikethrough does not hurt your SEO in itself. The text stays indexable, no penalty exists for the formatting, and in transparency, pricing and status contexts it improves the reader's experience. The real risks are indirect: schema that contradicts what is on screen, accessibility gaps that mislead assistive technology, and pages cluttered with obsolete crossed-out content that muddies their focus. Use it deliberately, back it with correct markup, and clean up when corrections outlive their usefulness.
