Quick answer: a sudden backlink spike in Semrush is not always a problem. If your website was added to the footer of a few client or partner websites, Semrush may count that link on every indexed page of those sites.
This is common with footer credit links such as Website support by 24WEB. One real footer link can turn into dozens or hundreds of reported backlinks because the same footer appears across product pages, blog posts, collection pages, and other templates.
Why one footer link can become hundreds of backlinks
Many websites use a global footer. When a support credit is placed there, the link appears sitewide. SEO tools then report each page that contains the footer as a separate backlink source.
- A 50-page website can create around 50 backlink rows.
- Three websites can quickly create a few hundred backlink rows.
- The links may all use the same anchor text, such as your brand name.
This can look dramatic in Semrush, especially if the domain previously had only a few known backlinks.
Is this bad for SEO?
Not automatically. A footer credit link can be normal when it is honest, approved, and connected to real work. The risk starts when footer links look artificial, excessive, hidden, keyword-stuffed, or created mainly to manipulate rankings.
Google’s spam policies explain that links intended to manipulate search rankings can be a problem. For a clean approach, keep support credits transparent and avoid aggressive anchor text. You can review Google’s official guidance here: Google Search spam policies.
Best practice for website support credit links
If a small business owner approves a credit link, I usually recommend keeping it simple and branded:
- Good: Website support by 24WEB
- Good: Website care by 24WEB
- Avoid: Best SEO expert Montreal web design Google Ads service
If the credit appears sitewide, adding rel="nofollow" can also be a clean choice. It keeps the referral visible for people while reducing the chance that search engines interpret the link as an attempt to pass ranking signals.
What to check when backlinks spike
Before panicking, check the referring domains, link placement, anchor text, and whether the links are follow or nofollow. If the spike comes from footer links on websites you genuinely support, it is usually explainable.
If the spike comes from unrelated spam domains, scraped pages, or strange anchors, document it and monitor it. Disavow should be treated carefully and usually only considered when there is a real manual action or a clear harmful pattern.
How this fits into practical website maintenance
Backlink reports are one part of ongoing website care. A small business website also needs technical checks, content updates, indexing checks, analytics review, and clear service pages. That is exactly the kind of work covered in my website management and SEO services.

Final takeaway
A backlink spike is a signal to investigate, not a reason to panic. If the links are honest footer credits from real websites, the main job is to keep them natural, transparent, and easy to explain.
