What is the Seznam Index Checker extension?#

Seznam Index Checker is an extension that ensures your new products and pages appear in the Seznam.cz search engine as quickly as possible. Every day it automatically checks which URLs from your feed or sitemap are in the Seznam index and which are missing. It then submits the missing URLs for priority indexing on its own, without any manual work on your part. The extension connects to the Seznam Webmaster service via API and pulls indexation status data from it.

The extension is ideal for:

Online stores with a large number of products that need to be sure all pages are indexed and customers can actually find them in search results.
New online stores, where natural indexation on Seznam can take several months. The extension significantly speeds up this process.
Online stores with frequent content changes — adding new products, changes to meta descriptions, page titles, switching to HTTPS, or publishing blog posts.
Online stores with weak internal linking or low authority on Seznam, where Seznam naturally indexes fewer pages.
Blogs, magazines, and other websites — the extension can also work with sitemaps, so it is not exclusively for online stores.

Pricing and billing#

The extension price is:

EUR 7 per month with monthly billing,
EUR 5.60 per month with annual billing.

The price applies to one online store (in Mergado) and is fixed, regardless of the number of URLs checked.

Due to technical dependencies, the extension is billed in accordance with the billing frequency chosen in Mergado Editor. Different billing frequencies cannot be selected for individual services.

The Seznam Index Checker extension has a 10-day free trial.

Note: Complete indexation of an online store with thousands of subpages can take 2 to 3 weeks, so the trial period will provide only an initial glimpse of results, not a complete picture.

Requirements for running the Seznam Index Checker extension#

Register your online store in Seznam Webmaster and verify it.
Copy the API key from Seznam Webmaster and paste it into Seznam Index Checker in Mergado.
In Mergado Editor, create a project and connect an export from your product feed or your website’s sitemap.

Key features#

URL indexation status check — The extension verifies every day whether URLs from your feed or sitemap are correctly indexed and appear in search results on Seznam.cz.
Automatic submission of indexation requests — It detects how many URLs are missing from the Seznam index and submits them for priority indexing on its own. It can submit up to 500 requests per day.
Identification of technical issues — It alerts you to errors such as database outages or an unresponsive server that may be slowing down or preventing indexation, so you can address the issues straight away.
Clear charts and statistics — It displays the development of the number of indexed pages over time, how many requests were submitted, and the overall index status of your website.
Overview of erroneous and redirected URLs — It lists URLs where the Seznam bot has recorded an error or redirect, along with context for their correct interpretation.

How to activate the Seznam Index Checker extension#

Activate the extension in Mergado Store: I want to activate → select the online store for which you want to enable the extension → Enable.

Working with Seznam Index Checker#

After activation and successful connection with the API key from Seznam Webmaster, the extension starts working automatically. The first data from Seznam Webmaster usually appears within a few days.

What you will see in the interface#

Indexation development chart — Track how the number of indexed pages from your feed or sitemap changes over time.
Number of submitted indexation requests — An overview of how many URLs were submitted to Seznam for priority processing in a given period.
Overall index status — How many pages of your website Seznam currently indexes (data comes from the Seznam Webmaster connection).
List of erroneous and redirected URLs — URLs where the server did not respond or returned an error during the check, and URLs that lead to a redirect.

How to correctly interpret erroneous and redirected URLs#

If some URLs show an error, it does not automatically mean they are actually broken. Most commonly it is a brief server or database outage at the time the extension was checking the URL. Redirected URLs indicate that the product at the original address is no longer available and the page points elsewhere — typically after a product has been renamed. These URLs are not submitted for indexing, because search engines prefer direct links to product pages. For customers, however, redirects are not a problem — they happen automatically.

How long to keep the extension running#

It depends on how frequently you change content. For one-time indexation of an entire online store, 2–3 months is usually sufficient. If you regularly add products, publish articles, or update existing content, it is worth keeping the extension running permanently — that way Seznam always has the most up-to-date version of your pages.

FAQ#

What is Seznam Index Checker and what is it used for?#

Seznam Index Checker is a Mergado Editor extension that speeds up the indexation of your pages in the Seznam.cz search engine. Every day it automatically checks which URLs from your product feed or sitemap are in the Seznam index and which are missing. It then submits the missing URLs for priority indexing — without any manual work on your part. As a result, your new products, articles, or updated pages appear in search results faster.

How long does it take to see indexation results?#

You will see the first data from Seznam Webmaster within a few days. However, for an online store with several thousand subpages, full indexation can take approximately 2 to 3 weeks. Without Seznam Index Checker, indexation would take significantly longer.

What is needed to activate Seznam Index Checker?#

To use Seznam Index Checker, you need to register in the Seznam Webmaster service and verify your online store there. Then copy the API key from Seznam Webmaster into Seznam Index Checker. After that, simply connect the output feed from Mergado or a sitemap.

Is the extension suitable for websites that are not online stores?#

Yes. Although it is primarily designed for online stores and product feeds, it works just as well for blogs, magazines, or other websites. Simply import a sitemap into Mergado instead of a product feed and the extension will ensure fast indexation of new content.

What is the difference between running the extension on a product feed and on a sitemap?#

A product feed contains only the product pages of an online store. A sitemap, on the other hand, can cover a wider range of subpages — categories, articles, static pages, and products.

What should I do if no data appears after activating the extension?#

The first data from Seznam Webmaster usually appears within a few days of activation. If data does not appear after a longer period, check that the API key has been entered correctly and that your online store is properly verified in Seznam Webmaster.

Why do some URLs appear as erroneous even though the page works?#

An error status does not automatically mean the URL is actually broken. Most commonly it is a brief server or database outage at the moment the extension was checking the URL. If the page works normally when visited again, ignore the error in the extension.

Why are redirected URLs not submitted for indexing?#

Search engines prefer URLs that lead directly to the target page. A redirected URL usually means the product has been moved or renamed and is no longer at the original address. There is no point indexing such URLs, because Seznam should ideally know and index the current target address.

How long is it advisable to keep Seznam Index Checker running?#

It depends on how often you change content. For one-time checking and quick indexation of an entire online store, 2 to 3 months is usually sufficient. However, if you add new products, articles, or frequently update existing content, it is worth keeping it running continuously so that Seznam always shows the most up-to-date version of your pages.
