Duplicate content analysis
We find duplicates and near-duplicates on your site: pages with the same content due to parameters, http/https and www versions, print versions, tags and pagination, repeated product descriptions, identical titles and meta — and give a plan for how to consolidate or remove them. Honestly — there is no separate Google "penalty" for duplicates, as people often fear, but they do hurt: they dilute signals, confuse the search engine about which version to rank, and waste crawl budget.
Duplicate content analysis — overview
A duplicate content analysis is a one-time check of where content repeats on the site and what to do about it: internal technical duplicates (one page available at different URLs due to parameters, sorting, http/https, www and non-www, slashes, print versions), near-duplicates (pages differing by just a couple of words, boilerplate text, thin variations), product description duplication (especially standard manufacturer descriptions on many cards), repeated or empty titles and meta descriptions, duplicates from tags, filters and pagination, and external duplication (your content copied, or, conversely, you copying others). We will work out how to consolidate duplicates correctly — via canonical, a 301 redirect or noindex, depending on the case. The goal is for the search engine to understand which version is the main one and not dilute signals. Honestly about the main point: this is diagnosis, not implementation and not a guarantee of ranking growth. And let us dispel a myth right away: there is no separate "duplicate content penalty" at Google — the problem is not punishment but that duplicates dilute link and behavioral signals between copies, the engine may show the wrong version, and crawl budget is spent on copies instead of the needed pages. So removing duplicates is useful, but it is not a "magic growth button" — rankings depend on many factors. We only identify the duplicates and give recommendations; implementation and any improvements are a separate task. It is a snapshot in time. Access to the code/CMS or the ability to crawl the site is needed; without such access the analysis is more superficial and some duplicates may go unrecorded. External duplication is checked by available data and third-party services — these are estimates with error margins, visible only within the tools' coverage and not always reflecting the real picture in Google and Yandex. What you get: a report with a map of duplicates by priority and recommendations on what and how to consolidate (canonical / 301 / noindex / rewrite); implementation is separate work. If the site is small and unique (for example, a 10-page business-card site with unique descriptions), we will honestly say the analysis is excessive — the duplicate risk is minimal. Picture this: instead of "everything seems unique" you learn that each product is available at 4 URLs with parameters, 200 cards have the same manufacturer description, and half the titles repeat. The base price starts from 9,000 ₽; it depends on the site and catalog size.
Problems we solve
- You suspect duplicate pages but do not know the scale or what to do.
- The wrong version of a page appears in search results.
- A catalog with filters and parameters multiplies copies.
- Product descriptions are copied from the manufacturer or repeat.
What's included in the Duplicate content analysis service
- Internal technical duplicates (parameters, http/https, www, slashes, print versions)
- Near-duplicates and boilerplate content with thin differences
- Duplication of product and category descriptions
- Repeated and empty titles and meta descriptions
- Duplicates from tags, filters and pagination
- External duplication (copies of your content or others on yours) — by available data
- Consolidation recommendations: canonical, 301, noindex or rewrite
- A prioritized report with a map of duplicates
What you get
- A clear, real picture of the duplicates and their scale
- Priorities: what to consolidate, what to block, what to rewrite
- A consolidation plan for each duplicate type (implementation is separate)
- Understanding that duplicates hurt via signals and budget, not a "penalty"
How the work goes: steps
- We clarify the structure and duplicate sources and collect access (code/CMS — where possible)
- We crawl the site, look for technical and content duplicates and check external ones
- We prepare a report with a map and a consolidation plan and review it with you

- Report and recommendations in plain language — clear without a technical background.
- In touch at every step and answering questions about the result.
FAQ
Do Google and Yandex penalize duplicates?
There is no separate "duplicate penalty" at Google — that is a common myth. The problem is different: duplicates dilute signals between copies, the engine may show the wrong version, and crawl budget is wasted. Removing them is useful, but it is not a guarantee of ranking growth.
Will you fix and rewrite everything yourselves?
The audit is diagnosis and a consolidation plan. Implementation (canonical, redirects, noindex) and rewriting descriptions are separate work: we can do the technical part, copywriting separately. We honestly separate what is included.
How is this different from a canonical audit and a thin content analysis?
A canonical audit is about the tag mechanism itself; a thin content analysis is about weak and empty pages; a duplicate analysis is about repeated content and how to consolidate it. They overlap (canonical is one of the solution tools), but the focus differs.
