Finding out that your SEO company built low-quality or spammy backlinks is unsettling, but it is rarely the emergency it feels like. The first thing to understand is what actually happened and how much it matters, because the right response is usually calmer and more measured than the panic the situation tends to create.

The Real Risk

Bad links built on your behalf fall into a few categories: links from low-value directories, links from unrelated or low-quality sites, links placed inside spun or thin content, and links bought in bulk. None of these help your rankings, and a campaign that relied on them was wasted money. The more important question is whether they can hurt you.

For most sites, the honest answer is that they will not. Google has spent years training its systems to recognize manipulative links and simply ignore them rather than penalize the site they point to. Google representatives have repeatedly said that ignoring spam links is normal behavior for the algorithm and that disavowing them is not a routine part of site maintenance. So if your traffic and rankings are stable, a batch of junk links is more an indicator of a poor provider than an active threat to your site.

The exception is a manual action. If Google has reviewed your site by hand and issued an “unnatural links” notice, you will see it in Google Search Console. That is a genuine problem that requires direct cleanup. Without that notice, you are almost certainly dealing with links that Google is already discounting on its own.

Audit the Backlink Profile

Before deciding anything, get a clear picture. Pull your backlink data from Google Search Console, and supplement it with a third-party backlink tool if you have access to one. Review the new links by referring domain, anchor text, and the type of page they sit on. You are looking for patterns: a sudden spike of links from the same low-quality network, repeated exact-match commercial anchor text, or links from sites unrelated to your business. Document what you find. This audit tells you the scale of the problem and gives you something concrete to raise with the provider.

When a Disavow Is Appropriate, and When It Is Not

The disavow tool lets you tell Google to ignore specific links. It is the right move in two situations: when you have a manual action for unnatural links, or when you have strong evidence of a deliberate, large-scale manipulative campaign that the algorithm may not have fully neutralized.

It is the wrong move for routine cleanup. The disavow tool is widely overused, and that is a real risk. If you disavow aggressively, you can accidentally cut off legitimate links that were helping you, which lowers your rankings. Because Google already ignores most spam, disavowing it usually changes nothing while exposing you to the chance of removing something useful. If your site has no manual action and stable performance, the safer choice is often to do nothing with the disavow file at all.

Stop the Practice and Reconsider the Provider

Whatever you decide about disavowing, the bad link building has to stop immediately. Tell the company in writing to halt all link acquisition until you have agreed on a quality standard. A provider that built spam links either did not know better or chose the fastest path over a sound one, and both are serious problems.

Ask them directly to explain their link methodology, show you sample placements, and describe how they vet linking sites. If their answers are vague, defensive, or they treat bulk links as normal, that is a strong signal to change providers. Quality link building is slower and earns mentions from relevant, credible sites. A company that cannot work that way is not protecting your long-term search performance, and continuing with them only repeats the same mistake.

A redirect tells browsers and search engines that a web address has moved and points them to a different one. When pages are removed, renamed, or consolidated, redirects keep visitors and search engines from landing on dead ends. An SEO company treats redirects as a routine but high-stakes part of technical work, because a sloppy redirect setup can quietly erode rankings and traffic. Here is how a competent provider approaches the job.

Choosing the right type of redirect

The first decision is whether a move is permanent or temporary. A 301 redirect signals a permanent change, and search engines treat the destination URL as the lasting replacement, passing along most of the ranking signals the old page had earned. A 302 redirect signals a temporary change, so search engines generally keep the original URL in their index and expect it to return.

An SEO company uses 301 redirects for the situations that actually call for them: a retired page, a renamed URL, a consolidated piece of content, or a domain change. It reserves 302 redirects for genuinely short-term cases, such as a maintenance page, a seasonal landing page, or an A/B test that will be removed. Using a 302 when a 301 is correct is a common mistake, because the move never gets treated as final and ranking signals may not transfer. A reputable provider checks the actual status code returned by the server rather than assuming the intended type was implemented correctly.

Redirecting removed and moved pages

When a page is deleted or replaced, an SEO company does not simply send every visitor to the homepage. It maps each old URL to the closest equivalent page, so someone who followed an old link still reaches relevant content. A retired product might point to its replacement or to the relevant category page. An outdated article might point to an updated version on the same topic. If no reasonable equivalent exists, the provider may decide that letting the URL return a proper 404 or 410 status is the honest answer, rather than forcing an irrelevant redirect that confuses users and search engines.

Avoiding chains and loops

A redirect chain happens when one URL redirects to a second URL that redirects to a third, and so on. Chains slow down page loads, waste crawl resources, and increase the chance that a search engine stops following before it reaches the final page. A redirect loop is worse: two or more URLs point back at each other, so the request never resolves and the page becomes unreachable.

An SEO company audits redirects to flatten chains, updating each old URL so it points directly to its final destination in a single hop. It checks for loops and fixes them as a priority, since a loop is a hard failure rather than a slow inconvenience. This kind of cleanup is part of ongoing maintenance, because routine CMS or hosting changes can introduce new chains over time.

Mapping redirects during migrations

Migrations, such as moving to a new domain, changing a URL structure, or replatforming, are where redirects matter most. Before launch, an SEO company builds a complete inventory of existing URLs by combining a site crawl with XML sitemaps, top landing pages from analytics, paid campaign destinations, and any redirects already living in the CMS or content delivery network. Every legacy URL is then assigned an intentional destination.

The provider tests these mappings against a staging environment, confirming that each old URL returns a 301 to the correct final page in one hop. After launch, it monitors crawl reports and Search Console for redirect-related errors and verifies that important pages keep their visibility.

Fixing redirects to or from broken URLs

An SEO company also reviews existing redirects that point to URLs that no longer work, since a redirect leading to a 404 page leaves the visitor stranded. It repoints those redirects to a working page and corrects internal links so they reference the final URL directly instead of relying on a redirect at all. Treating redirect health as a recurring check, rather than a one-time fix, keeps the site clean as it grows and changes.

An SEO company measures content performance by looking at each individual page rather than the site as a whole. A blog post, a service page, and a location page all serve different purposes, so they are not judged by the same numbers. The goal is to answer a practical question for every piece: is this page found, is it useful, and does it contribute to the business? To get there, an SEO company combines data from Google Search Console, an analytics tool such as GA4, and rank tracking, and reviews it page by page on a regular schedule.

Visibility: traffic and impressions per page

The starting point is how much organic traffic and how many impressions each page earns. Search Console reports both at the page level, so the team can see which posts pull search visibility and which sit unseen. A useful detail in 2026 is the gap between impressions and clicks. A page can hold steady or growing impressions while its actual visits slip, which often points to a click-through problem in the title and meta description rather than a ranking problem. Tracking the two figures separately keeps the diagnosis honest.

Keyword coverage and rankings

Next, the SEO company checks which queries a page actually appears for and where it ranks. Search Console shows the full list of queries driving impressions to a single URL, not just the keyword the page was written to target. This reveals two things: the keywords the page already covers well, and the related searches it ranks for on page two or three, where small improvements can move it into reach. It also flags keyword overlap, where several pages compete for the same query and split their potential.

Engagement on the page

Traffic alone does not show whether visitors found the content helpful. Engagement signals fill that gap. SEO companies look at how long people stay, how far they scroll, and whether they move on to another page or leave immediately. Scroll depth and time on page are commonly tracked with behavior tools, and a healthy return visitor rate suggests the content is building a repeat audience rather than collecting one-time clicks. Weak engagement on a page that gets steady traffic is a clear signal the content needs work.

Conversions and assisted conversions

The most important question is whether a page contributes to business results. Direct conversions, such as a form submission or a sale that happens on or right after a visit, are tracked in the analytics tool and tied to the entry page. Many visitors do not convert on the first visit, though. They discover a brand through a search result, leave, and return later through a direct visit or another channel. Assisted conversions credit content for that earlier role, so an SEO company uses attribution reporting to see which pages start journeys that finish elsewhere. A page can be valuable even when it rarely closes the sale itself.

Content decay over time

Content rarely performs at a fixed level. A page often reaches a peak, plateaus, and then slowly declines in clicks and rankings as competitors publish fresher material and search results shift. This pattern is called content decay. SEO companies catch it by comparing a recent period against an earlier one, for example the last 28 days against the previous 28, or the last several months against the same span a year earlier. Pages with a clear downward trend in clicks, impressions, or click-through rate are flagged for attention.

Deciding what to update, prune, or expand

The measurement only matters when it leads to a decision. After reviewing the data, an SEO company sorts pages into a few groups. Pages that once performed well but are now decaying are candidates to update with current information and stronger coverage. Pages ranking just below the top results are candidates to expand, since they are close to a meaningful gain. Pages with almost no traffic, no rankings, and no conversions after a fair period may be pruned or merged, which removes weak content that can drag on the rest of the site.

A reliable SEO company reports these findings clearly and ties each recommendation back to the numbers behind it. Content performance is not a single score. It is an ongoing review of visibility, engagement, and contribution for each page, and a steady process of acting on what that review shows.
