OK | NOT Check Findings

Are there bad link patterns?

Search for the site in Ahrefs Site Explorer, with "include subdomains" selected.

We'll use this data for the next many checks.

Start compiling a spreadsheet of all bad links, which we'll disavow at the end.

Ahrefs is recommended because they have the largest pool of backlink data. Majestic or Moz OSE also work; but provide less data. All other tools use one of these sources; usually Majestic or Moz.

Are there sudden gains in linking domains?

On the timeline of linking domains, are there apparently instant spikes greater than 5% upwards?

If so, review links acquired in that date range under Linking Domains > New.

For each, ask: is there a reason for these links that can be related to real marketing?

If not, add to your list of bad links. Log an issue for each until a disavow is approved (we'll cover that at the end).

This is so effective at revealing spammy link schemes, Google has suggested that it works for them too.

Are there rapid drops in linking domains?

On the same graph as above, are there any apparently drops of greater than 5% of linking domains?

This is never a natural pattern for natural, editorially-acquired links. More detail.

IF RAPID LOSS: Review Lost Links

If we identified a rapid loss of backlinks the next step is to dump a CSV of all lost links from the report: Linking Domains > Lost in Ahrefs.

Before marking this resolved, do three things:

  1. Verify that this sort of thing has ceased entirely (stop spamming).
  2. Look for patterns in these links that could help to identify more.
  3. Export a CSV of these problem links for disavow, as well as any others.

Why also disavow links that are already lost? Because Ahrefs and Google run completely different crawlers and databases. They'll be similar but never identical.

Long-Term Link Trend

Does the # of linking domains increase or decrease over a long time horizon?

Losing backlinks over time should be an obvious bad signal: be it a direct or indirect ranking factor. Mark any such trend as an issue and don't mark it resolved until we've reversed the flow of new linking domains.

> 10% Anchor Text

Does anchor text for a word or phrase exceed 10%?

This can be viewed lower on the Ahrefs Site Explorer dashboard. If so, it's extremely likely that the site is already being penalized in relation to the Penguin algorithm. More on this problem.

Very Low Authority

Does the domain have low authority?

For this step, you may actually want to check Moz Open Site Explorer instead of Ahrefs (free for checking just one domain). Remember: Moz tracks less links, but their link metrics have been historically more sophisticated.

The level of authority needed to be competitive will vary based on ranking goals, but in general, a Domain Authority less than 50 will be a problem for almost any site.

Top Referring TLDs

Are more than 25% of the referring sites on a TLD that isn't associated with our primary target country?

You can check this in the "Top Referring TLDs" report in Ahrefs (on the lower half of the Site Explorer dashboard). You want to see >50% of your backlinks from either a generic TLD, like .com or .org, or a ccTLD in the same country (like .ca for Canada).

Too many links from a different country than you are targeting may establish your site as only being relevant to that audience. Worse, in extreme instances, it may serve as a webspam signal.

Where have most of their links come from?

Problem Links

Navigate to Inbound Links > Links on the left menu in Ahrefs, and filter by 01 Backlink/Domain (top of page).

This will show us all linking domains to the site, as well as where on the site the links appeared. It also removes the clutter that we'd otherwise deal with from frequent/sitewide links on domains where we've already achieved links.

We'll use this information to perform the next many checks.

In DMOZ?

Is dmoz.org included?

If no, we recommend submissions every six months until listed. Be sure to carefully follow guidelines (especially surrounding objective language) and check bottom of the category you're submitting to confirm that an editor is active for that section.

For the most part, link building is outside the scope of this audit, but for whatever reason, a backlink from DMOZ still carries absurd amounts of value for a site's rankings in Google. And it can be obnoxiously difficult to obtain, so be persistent.

UGC Link Wheeling

Do any links have anchor text that is just completely unrelated/nonsensical?

Most commonly, this occurs when a portion of our site is being spammed/exploited, such as through a comments, user profiles, or a URL shortener feature. Black hat SEOs will then use this to build a larger link wheel whereby the spam more black hat links from other sites at those particular pages.

This is a very bad signal - these links should more often be disavowed, and any site features that were exploited to place the offending links should usually be removed.

Purchased Links

Do any links appear to both #1 purchased and #2 without the "nofollow" directive?

The most obvious indicator of such will be links that are literally positioned besides text that says "advertisers" or "sponsors".

That will be followed by links in a sidebar/footer that are there for no apparent reason.

WordPress Theme Links

Are there any backlinks from sponsored WordPress themes?

You can recognize these as links in the footer of every page of a site, usually without any context outside of a "Designed by:" or "Theme sponsored by:" designation.

Private Network Links

Do any links appear to come a content farm?

You can spot a content farm by masses of low-quality posts, each littered with oddly-positioned anchor text backlinks to irrelevant home pages, on varying topics that are of no clear value to humans.

Generic Directories

Are there backlinks from generic web directories that approve all submissions?

The problem here is that these sites typically have little-to-no editorial discretion. That means you're sharing real estate besides all varieties black hat spam, porn, gambling, and so forth. This inevitably equates to what Google defines as a "bad neighborhood".

You can usually spot these as having a homepage of website categories, that beings "Arts & Humanities" and ends in "Zoology". Exception is made when there is:

1. Requirement of a certain niche (like the AllTop blog directory or address-verifying business directories)
2. Other editorial discretion - like DMOZ or the Yahoo! directory - which are somewhat diffcult to get into in spite of being generic

Free for all Links

Are there backlinks from free-for-all link sites?
These are very similar to generic directories, but will appear a bit differently. You can usually spot them by having names like "a1bestfreelinks.com" and other such sites.

What are their most linked to pages?

OSE: Top Pages tabMajestic: Pages tab
GWT: Traffic > Links to Your Site > Your most linked content

Does that coordinate with top organic pages?

GA: Traffic Sources > Sources > Search > Organic > Landing Page
