What the Yandex IKS score is and how it is calculated
IKS stands for the site quality index in Russian. Yandex calculates it on its own and shows it to site owners inside Webmaster. It replaced an older citation index that relied mostly on links, a metric that lost its meaning once link trading took over. IKS is built differently: Yandex describes it as a measure of how useful a site is to users.
The exact formula is not published. What is known is that audience size, user satisfaction and trust in the site are taken into account, with data drawn not only from search but also from other Yandex services such as maps and the business directory. So IKS is not a grade for your design or copywriting. It is closer to a picture of how visible and trusted your company is within the Yandex ecosystem.
Where to find the score and how to read changes
In Webmaster the score appears in the site summary and in a separate section with its history. Yandex also offers a public check, so you can look up a competitor without access to their account. The index is refreshed periodically rather than daily, so a small dip between two updates is not a reason to worry.
Typical reasons for movement are fairly ordinary:
Never draw conclusions from a single update. Compare several months of dynamics against traffic and leads. If traffic is steady but the score fell, check your company profile on Yandex Maps first.
- seasonal changes in demand and visits;
- your activity in maps and the directory;
- a change in the calculation method on Yandex’s side;
- a shift in how users behave on your site.
Does IKS affect search rankings?
No. Yandex states directly that IKS is not used in ranking. It is an indicator, not a lever. A site with a lower score can easily rank higher for a specific query if its page answers the question better. A rising score is a consequence of audience and trust growing, not the cause.
That gives you a simple rule: a contractor who promises to raise your IKS deserves some suspicion. Faking traffic or behavioural signals breaks Yandex rules and risks penalties, and those hit your rankings, not just the number.
IKS for Uzbekistan sites: adjust for the market
For most local companies, search traffic comes mainly from Google, and the Yandex audience is noticeably smaller. A modest score for a Tashkent online shop, clinic or training centre is therefore normal, and comparing it with Russian sites makes no sense.
Even two local competitors can differ simply because of audience mix: one site is opened more often from Yandex, the other from Google, Instagram and Telegram. So a competitor’s IKS will not tell you how many customers they have. For that you need other sources and cautious estimates.
How to use IKS sensibly, and how not to
IKS works for three jobs: a rough comparison of scale against competitors, a quarterly note of long-term dynamics, and a background line in a report. It should not be used like this:
When choosing a site for an article or an ad placement, look first at topical fit, a living audience and whether the placement brings real people. A small niche site with a precise audience is often worth more than a big portal that has nothing to do with your field.
- making IKS growth the goal of an SEO contractor;
- judging a link donor site by IKS alone;
- comparing sites of different size and topic head to head;
- buying “IKS boosting” or traffic inflation.
What actually moves the score
There are no special tricks, and no separate budget is needed. The score follows the health of your online business: a useful site with a growing audience, a complete Yandex Maps profile with reviews and current details, speed, convenience and no rule violations.
Everything starts with the site itself: clear structure, fast loading on mobile, pages that answer real customer questions, working request forms and payment through Click or Payme. At markdev we build turnkey websites on exactly this logic: the business goal and incoming enquiries first, metrics second.
In an SEO report, put visibility for target queries, clicks from search, traffic and leads first, and keep IKS as background. If you want to discuss your website or work out which numbers matter for your case, get in touch with markdev.
FAQ
What is the Yandex IKS score in simple terms?
It is Yandex’s site quality index. It reflects audience size, user satisfaction and trust in the site. The formula is not disclosed, and the value is updated periodically.
Does a high IKS help a site rank higher?
No. Yandex says IKS is not used in ranking. It is an indicator that follows audience and trust growth, not a cause of good positions.
Why did my IKS drop when nothing changed?
The cause may be seasonality, changes in other Yandex services, a new calculation method or user behaviour. One update proves nothing: compare the trend with traffic and check your Yandex Maps profile.
Should IKS be a KPI for an SEO contractor?
It is better not to. Judge the work by visibility for target queries, clicks, traffic and leads. IKS can be shown as extra background.
