Are Footer and Sidebar Links Good for SEO?

Footer and sidebar links are real links and Google follows them, but they carry noticeably less weight than links placed inside body content. Search engines discount repeated boilerplate that appears identically on every page, and sitewide footer links with commercial anchor text are named directly in Google's link spam policy.

Why position on the page changes a link's value

Not every link on a page is treated equally, and that isn't a theory — it's the design intent behind Google's "reasonable surfer" model, described in a Google patent granted in 2010 (US 7,716,225). Rather than splitting a page's authority evenly across every outgoing link, the model weights each link by how likely a real person is to click it. Position, font size, whether it sits in body copy or in a navigation block, and how many other links surround it all feed into that estimate.

Apply that to a footer. A link sitting under 4,000 words of an article, in context, with anchor text that describes what's on the other side, has a plausible click. The same URL repeated in a 60-link footer at the bottom of every page on the site does not. The link still exists, still gets crawled, and still counts for discovery — it just isn't carrying the weight people assume.

The second factor is deduplication. Boilerplate is, by definition, the part of the page that doesn't change. Search engines have identified and down-weighted repeated template regions for a long time, precisely so that a menu repeated across 10,000 pages doesn't read as 10,000 endorsements. That mechanic also explains why the answer to "do multiple links from the same site count more than once" is mostly no.

When footer links cross into spam

There's a specific pattern Google names. Its link spam policy lists as an example of unnatural linking: "widely distributed links in the footers or templates of various sites."

The classic version is the web designer's credit link — "Website by [Agency Name]" in the footer of every client site, using a commercial keyword rather than the agency's brand. It's an easy footprint to detect: hundreds of unrelated domains, identical anchor, identical placement, no editorial reason for any of them. The paid version is the same shape with money changing hands.

The practical test is whether the link would exist if search engines vanished tomorrow. A footer link to your own privacy policy would. A footer link on a plumbing supplier's site pointing at "cheap car insurance quotes" would not.

What footer and sidebar links are genuinely good for

Dismissing them entirely is the opposite error. Boilerplate links do three jobs well:

Crawl paths. A link in the footer of every page guarantees the target is reachable from anywhere on the site — the simplest fix for orphan pages. If a page can only be reached through a search box or a paginated archive, a footer link solves that in one edit.

Distributing authority to key pages. Sitewide links do pass value, even discounted. That's why pricing, contact, and top category pages routinely live in the footer of well-built sites. The weight per link is low; multiplied across every page on the site, it isn't nothing.

Users. Footers are where people look for contact details, terms, support and social profiles. Sidebar modules with related posts genuinely reduce bounce. Both are legitimate uses that happen to help SEO indirectly.

Rules of thumb that hold up

Keep the footer small. A footer with 15 well-chosen links concentrates far more value per link than one with 120. Mega-footers built to "spread link equity" achieve close to the opposite.

Use brand or descriptive anchors, not money keywords. "Pricing" is fine. "Buy cheap widgets online" repeated on 5,000 pages is a signature. Anchor text is where sitewide links most often get sites into trouble.

Don't buy or sell them. A paid sitewide footer link is a paid link, and being sitewide makes it trivially easy to spot at scale.

For external links, prefer in-content placement. If you're negotiating a link on someone else's site, one in-content mention inside a relevant article beats a permanent footer credit, even though the footer version looks like more real estate.

Sidebar "partner" boxes are weak. A blogroll or link-partners widget is the modern descendant of the reciprocal links page — visibly a link exchange, off-topic, and easy to discount. The same trade placed inside relevant articles reads completely differently. That in-content placement is the whole design of Backlinkster: swaps go into real body content and are verified live by code, rather than parked in a sidebar module where they earn little and signal a lot. See the plans — five verified swaps a month on the free tier.

Auditing your own boilerplate

Three checks, ten minutes:

Count the links in your footer and sidebar. If the total exceeds roughly 20–25, ask what each one is for. Cut anything that exists "for SEO."
Read the anchor text as a list. Written out in a column, commercial keyword anchors stand out immediately.
Check where your inbound sitewide links come from. In Ahrefs, Semrush or Search Console, sort referring pages by domain — a domain sending thousands of links is almost always a sitewide placement counting as roughly one. If those sources are low quality, they're candidates for disavow.

Frequently asked questions

Are footer links good for SEO? They work but carry less weight than in-content links. Google's reasonable surfer model weights links by likely clicks, and boilerplate repeated on every page is heavily discounted. Footer links are good for crawlability, navigation and pointing at key pages — not for ranking power.

Do sidebar links pass link juice? Yes, but at a reduced rate compared with a link in body content. Sidebar and footer links are template regions that search engines identify as boilerplate and down-weight, so a sidebar link passes some value rather than none.

Are sitewide footer links spam? Not inherently — your own navigation and legal links are normal. They become spam when distributed across unrelated sites with commercial anchor text, which Google's link spam policy names explicitly as "widely distributed links in the footers or templates of various sites." Paid sitewide links fall squarely in that category.

Does a link in a footer count as a backlink? Yes. It's a real link, gets crawled, and appears in backlink tools. It just contributes less than an editorial in-content link from the same site would. One relevant in-content mention is worth more than a permanent footer credit.

How many links should a footer have? There's no official limit, but keep it purposeful — roughly 15–25 links covering navigation, legal pages and key categories. Very large footers dilute the value each link carries and look built for search engines rather than people.

Should I ask for a footer link when swapping backlinks? No. Ask for an in-content link inside a relevant article. Footer swaps are lower value, easier to spot as an arrangement, and easier for the other party to quietly remove.

The bottom line

Footer and sidebar links are a navigation tool that happens to pass a little authority, not a ranking tactic. Keep your own boilerplate short, descriptive and honest; when acquiring links elsewhere, spend your effort on in-content placements where the reasonable-surfer weighting is on your side. The footer link that's genuinely useful to a visitor is the one that was never a problem in the first place.
