Does Google really evaluate all content on a page the same way for ranking purposes?

What does it really mean when we say 'all content is considered as a whole'?

When Martin Splitt talks about 'all content', he is not getting into specifics. Main text, user comments, rating widgets, ad blocks, pop-ups, overloaded footers — Google evaluates the page as a whole. There’s no distinction between what you lovingly wrote and that terrible forum you integrated three years ago.

This holistic approach isn't new, but it clarifies an often overlooked point: the perceived quality of a page dilutes if you let entire areas fall apart. A brilliant article drowned in a sea of user spam won't be saved by its intrinsic quality — the algorithm sees the whole, and the whole stinks.

Why is this statement critical for UGC sites?

Platforms relying on User-Generated Content (forums, marketplaces, review sites) are directly in the crosshairs. If your users post mediocre, duplicated, or spammy link-filled content, it's your site that suffers in ranking. No get-out-of-jail-free card just because 'it's not us, it's the users.'

The problem becomes acute when you have thousands of pages with unmoderated contributions. Google is not going to distinguish between the 12% of relevant comments and the 88% of junk — it assesses the overall quality signal, and if that signal is weak, your positions will collapse. We've seen historic forums lose 60-70% of traffic after Core Updates, simply because no one was cleaning up old discussions.

Is hidden or less visible content also affected?

Splitt doesn't specify, but field experience suggests that the weight of content varies based on its visibility. A footer block with 200 poorly placed internal links will have less impact than a spam block right in the middle of the article. But be careful: 'less impact' doesn't mean 'no impact.'

Accordion, tab, or lazy-loaded content is generally indexed and taken into account — Google has always said it considers the complete DOM. So if you hide mediocre text behind a 'Customer Reviews' tab to make it pretty, that text still counts. The real question is: how much does it weigh in the final calculation? We don't have a numerical answer, just fuzzy correlations.

• All visible content is evaluated: main text, UGC, widgets, ads, footers.
• No distinction between content created by you or your users — you are responsible for everything.
• The overall quality of a page dilutes or strengthens the ranking signal — a good article can be sunk by poor auxiliary content.
• Hidden contents (accordions, tabs) remain indexed and count in the algorithmic evaluation.
• UGC sites must actively moderate to avoid degrading the quality signal perceived by Google.

Is this statement consistent with what we observe in the field?

Yes, and it's even a confirmation of what many suspected. Sites that have heavily cleaned their poor UGC have often seen traffic rebounds post-Core Update. Conversely, platforms with unmoderated user content have taken algorithmic hits without understanding why their 'quality editorial content' was no longer sufficient.

The catch is that Google remains willingly vague about weightings. How much does a 3-line spam comment weigh against a well-crafted 2000-word article? No public data. We’re flying blind, testing hypotheses on our own sites or those of clients. [To be verified]: the exact weighting between main content and auxiliary content remains a black box.

What are the blind spots of this statement?

Splitt says nothing about dynamic or personalized content. If your site displays different blocks based on geolocation, user history, or A/B testing, which version does Google evaluate? Theoretically, the one that Googlebot sees — but if you serve a degraded version to the bot for performance reasons, you're shooting yourself in the foot.

Another point not addressed: display ads and third-party scripts. We know that Core Web Vitals penalize heavy ads, but does the text of ad slots (often duplicated across thousands of sites) also degrade the unique content signal? Nobody states this clearly. [To be verified]: actual impact of ad content on text ranking, beyond UX.

In what cases could this rule be nuanced?

Google has already admitted that certain 'technical' contents (legal mentions, T&Cs, standard footers) are probably less weighted in quality assessment. But there has never been an exhaustive list. If you have a forum with 10,000 old discussions and 500 recent quality discussions, is Google going to average them all or favor freshness? Observations suggest a mix of both, with a time bias — but nothing official.

Another nuance: sites with sealed sections (professional blog vs community forum) sometimes seem to fare better if the two sections do not have the same quality level. As if Google segmented the evaluation slightly by page typology. But this is a working hypothesis, not a proven fact. [To be verified]: is there internal segmentation by content type within the same domain?

How do I audit the auxiliary content on my site?

Start by identifying all content sources: comments, user reviews, forums, social widgets, heavy footers, sidebars with auto-generated text. Crawl your site with Screaming Frog or Oncrawl and export the visible text / HTML code ratio — if you fall below 10-15% on strategic pages, you have a dilution problem.

Then, manually review a sample of your most important pages. Ask yourself: If I were an average user, would I find this content useful or polluting? Auto-generated 'Similar Articles' blocks that are irrelevant, 2012 comments talking about an outdated version of your product, flashing ads — all of this sends a signal of mediocrity.

What concrete steps can I take to improve the overall signal?

For unmoderated UGC: implement a post-moderation system (automated + human). Nofollow outgoing links in comments, ban recurring spam keywords, remove or hide low-value contributions. Some sites have deindexed their old forum discussions — radical, but effective if they drag down overall ranking.

Regarding technical content and footers, lighten them as much as possible. You don’t need 50 internal links in every page footer — 10-15 are more than enough. Pass legal mentions, T&Cs, and similar pages to noindex if they don’t bring any organic traffic. The same goes for 'date archive' or 'tag archive' pages that dilute content without SEO value.

What mistakes should I absolutely avoid?

Don't fall into the trap of over-cleaning. Deleting all comments at once can kill your freshness and engagement signals. Google also values diversity in formats and contributors — a 100% editorial site without interaction loses some of its ranking potential on complex informational queries.

Also, avoid hiding mediocre content hoping Google won't see it. Accordions, tabs, and lazy-loading do not prevent indexing — they sometimes delay it, but the content always gets evaluated in the end. If you don't want it to be taken into account, remove it or set it to noindex via meta robots or X-Robots-Tag (for entire sections).

• Audit the text/code ratio of your strategic pages and identify dilution areas.
• Actively moderate UGC: remove or hide spam, old, or off-topic contributions.
• Lighten footers and sidebars: limit to 10-15 links, remove auto-generated content of no value.
• Nofollow outgoing UGC links to avoid passing PageRank to dubious destinations.
• Deindex or noindex technical pages without SEO value (archives, tags, T&Cs if they don't drive traffic).
• Do not blindly delete all user content — keep what brings freshness and engagement.
