Link Building Audit in Burgos — Discover Whether Your Links Help or Hurt You

A backlink audit collects the complete external link profile using multiple data sources (Ahrefs + Semrush for maximum coverage) and analyses: total number of backlinks and unique referring domains, authority and traffic of each linking domain, anchor text distribution, follow/nofollow ratio, profile growth velocity, and comparison with competitors ranking in the Top 3 for target keywords.

There are situations where a backlink audit is urgent: sudden drop in organic traffic coinciding with a Google spam-related update (SpamBrain updates), receipt of a manual penalty notice in Google Search Console, suspicion of a negative SEO attack where a competitor is pointing toxic backlinks at your website, or detection of over-optimised anchor text patterns in the profile. In these cases, acting quickly can minimise the damage.

The link building audit is the diagnosis: it analyses the current state of the backlink profile and identifies problems and opportunities. The link building strategy is the treatment: the action plan to build new quality backlinks and improve the profile. The audit necessarily precedes the strategy: without knowing the starting point, an efficient strategy cannot be designed nor realistic objectives established.

Toxic backlinks can arrive in three ways: as residue from low-quality link building strategies by previous SEO providers, as the result of a negative SEO attack where a competitor points thousands of spam backlinks at your website to trigger a penalty, or simply because your website is old and has accumulated links from websites that were once acceptable but have degraded in quality over time.

The clearest signs of a problematic backlink profile are: sudden drop in organic traffic without changes to the website, a high percentage of over-optimised anchor texts with exact keywords, many backlinks from domains with irrelevant languages or topics, a large number of backlinks from domains with very low DA and no real traffic, and many chained backlinks (website A links to website B which links to your website) rather than direct editorial links.

Google can react in two ways to artificial link profiles: through algorithmic penalty (SpamBrain and Penguin updates automatically devalue links it considers spam) or through manual penalty (a Google reviewer detects the problem and applies a sanction that appears in Search Console). Algorithmic penalties are harder to detect; manual ones are more severe but also clearer regarding the cause.

The first indicator to analyse is the number of unique referring domains pointing to the website: the diversity of sources is more important than the total volume of backlinks. A website with 50 backlinks from 50 different domains usually has a more solid profile than one with 500 backlinks from only 5 domains. We compare this figure with competitors in the Top 3 to identify the authority gap that explains the ranking difference.

We analyse the profile distribution by authority ranges (DA/DR 0–20, 20–40, 40–60, 60+) and by real editorial quality of the linking domain. A healthy profile has most backlinks on websites with DA/DR between 20 and 60 and a reasonable number of backlinks on high-authority websites. A profile that concentrates all backlinks on DA 0–20 websites is a sign of low-quality link building or very slow natural accumulation.

Follow backlinks transfer PageRank; nofollow ones, in principle, do not (though Google has acknowledged using them as signals in some cases). A completely artificial profile usually has an anomalous ratio of follow links, because spam creators configure all links as follow to maximise transferred link juice. A natural profile has a mix of follow and nofollow reflecting the diversity of contexts where the website is mentioned.

Anchor text distribution is one of the clearest indicators of whether a backlink profile is natural or artificial. A natural profile has most anchor texts using the brand name, direct URL or generic anchor text ("click here", "read more"). An over-optimised profile has a high percentage of anchor texts with exact keywords ("SEO agency Burgos", "web design Burgos") which clearly signals an artificial link building strategy.

Benchmarking against competitors ranking in the Top 3 for target keywords is the most action-oriented analysis of the entire audit. It shows exactly the authority gap to be closed, what types of domains competitors have that you do not, and what backlink opportunities you could exploit by being active in sectors related to your activity in Burgos.

The toxic backlink list classifies all medium and high-risk domains with their justification and the recommended action: keep, monitor or disavow. For high-risk backlinks, we prepare the disavow file ready to upload to Google Search Console, following the specific format the tool requires.

During the audit we identify backlinks pointing to URLs that no longer exist on your website (deleted pages, changed URLs) and generating 404 errors. These backlinks are losing the link juice they could transfer. The solution is to implement 301 redirects to the most relevant page on the current website to recover that value immediately.

The final benchmark of the report compares your backlink profile with that of the 3 direct competitors best ranked for your main keywords. This comparison clearly identifies the authority gap to close, the types of media where you have less presence than the competition, and specific backlink opportunities in sources your competitors have that you do not.

The report concludes with a specific link building action plan for the project: recommended monthly backlink volume, priority media types according to sector and competition in Burgos, recommended anchor text strategy to avoid over-optimisation, and implementation schedule. This plan serves as the basis for the monthly link building service if the client decides to continue it.
