Why is Search 3.0 different from other search datasets?

We believe that our data is more reliable, robust, and fresh than any other SEO tool out there because:

  1. We provide traffic estimations for every traffic-driving URL on every keyword every day. This is enabled by our proprietary Daily Search Volume that derives the most granular traffic estimations available.
  2. Our keyword database is continually expanding. While quantity is incredibly important, the amount of keywords available is meaningless without the quality of keyword data that SEO and Paid Search Marketers need. Search 3.0 data powers our tools to provide more targeted, precise keywords - not just every single keyword that has ever been searched (you don’t need ‘best laptop 2017’ as a keyword for your SEO strategy), or duplicate keywords you have to manually sort through yourself (a problem we hear about other tools all too often).
  3. Similarweb is the only tool that provides data for the "last 28 days." You can see what’s trending, and what’s performing to stay one step ahead. Even evergreen content should be backed up by the most up-to-date search terms and search volume.
  4. Our Advanced Clicks and Search Volume metrics provide a more accurate picture of what’s happening on the SERPs

How do we calculate our search metrics?

Similarweb aligns with the SEO industry standard for search metrics, measuring "Search Volume" and "Clicks" based on keyword, country, and URL. "Clicks" represent individual instances of a link being clicked from the SERP, while "Search Volume" reflects the number of searches for a specific keyword on Google. 
Our models precisely predict the CTR (click-through-rate) for every URL, and we can estimate how many clicks were made with the Search Volume of a keyword.

Additional metric definitions:

  • Volume is based on comprehensive data from our contributory network and the real searches they are making. Further modeling is applied that enables us to predict the ration between mobile and desktop volumes as well. 
  • Click-Through-Rate (CTR) is based on our data from our contributory network, Google Ads, and Google Search Console. Further modeling provides a prediction for the CTR for every URL in the SERP, and is updated every day so that you get a real-time CTR.
  • Clicks is a hybrid module combining the clicks data from our contributory network and our CTR model, providing estimations to a wide coverage of clicks overall keyword-url pairs.
  • Paid Competition - "Competition" is a Google Ads metric that indicates how competitive ad placement is for a particular keyword. It is determined by the number of advertisers bidding on each keyword. In essence, a higher competition score suggests that more advertisers are competing for ad placement using that keyword.

Where can I use Search 3.0 data?

The features that currently use Search 3.0 data are: 

In Website Keywords and Keyword Analysis you’ll benefit from a much larger selection of keywords to analyze per domain, which is great for analysis of longtail keywords driving clicks. This includes mobile keywords, as well as a much greater level of search volume accuracy for each keyword, right up to the present day.

You’ll also get a combined mobile and desktop view called ‘All traffic’ as well as the option to view them separately. You will also see a new ‘Last 28 days’ timeframe that allows you to view the freshest, trending keywords as well as a daily, weekly and monthly traffic trend per keyword group and site.

You can switch views from Organic to Paid traffic insights for the chosen website, keyword or keyword list on both these feature pages. 

In Landing Pages you’ll also benefit from the same increase in keyword and URL coverage, as well as the absolute numbers for clicks and click trends for any URL. 

The Keyword Generator tool has been running on Search 3.0 data already, benefiting from the huge boost in longtail coverage, giving those conducting keyword research even great depth to analyze.

  Note: These are only the initial features that are running on the new Search 3.0 dataset. Over the coming months, we will be ensuring our whole suite of SEO tools are running on the Search 3.0 dataset and providing  new levels of insight accuracy.

  Note: The original Keyword Analysis, Landing Pages (Organic Pages) and Website Keywords features will remain live in the platform, running on our older dataset for the time being, but eventually these will be sunsetted. 


Q: How far back can Search 3.0 data be applied?

A: The data is available from January 1st, 2023, and will continue to be added as we move further in time.

Q: What is the granularity available with the Search 3.0 dataset?

A: The Search 3.0 dataset offers  daily, weekly, and monthly volume and clicks per keyword URL for both desktop and mobile. This means that the data is updated daily, providing near real-time keyword analysis.

Q: What countries will be accessible during the Search 3.0 BETA?

A: Search 3.0 is available for all countries supported on Similarweb. Each user can access the country filters associated with their account.

Q: For which search engines do you provide estimates?

A: Volume data is based solely on Google searches, which is the standard in the industry. When it comes to traffic estimation, our main focus is on Google. However, for desktop, we also estimate clicks for all search engines available.

Q: What are “Clicks,” and how do they differ from “Visits” that we have in the platform today?

A: Visits, also known as sessions, represent the number of times a site was visited within a 30-minute session. Clicks, on the other hand, indicate the number of times users searched and then clicked to go to a site. In the case of multiple searches within a visit, each click from Google to the site is counted as a separate click. 

Q: Why is keyword traffic different between the previous keyword data and Search 3.0?

A: Each of the new pages is built on a different infrastructure, using a different data methodology. The new Search 3.0 dataset, which collects data from the SERP, combines it with real user behavior from Similarweb's largest contributory network  and utilizes a machine learning algorithm to create estimations at the keyword level per URL. This change enables us to deliver the freshest data with greater granularity and expand our coverage. Note that in the new Search 3.0 pages, the metric you are seeing traffic for is Clicks, while on the old Keywords pages, the metric was Visits

Q: Why are Total Clicks not aligned with MMX Search Visits? 

A: The MMX represents the entire site search traffic, while Total Organic Clicks only represent traffic for identified keywords. There are cases where we estimate organic traffic but cannot identify the specific keywords that contribute to it. 

Q: Will the transition to Search 3.0 impact my existing keyword lists, dashboards and reports?
A: No, your existing keyword lists, dashboards and reports will remain intact during the  Search 3.0 BETA. The new dataset will only affect the new features explicitly mentioned.

Q: Will the transition affect my account settings or configurations?
A: No, the transition to Search 3.0 will not impact your account settings or configurations. You can continue to use the platform as usual, and any changes will be seamlessly integrated into the existing framework.

Q: Can I still access the old keyword data using the old dataset?
A: Yes, old dataset will remain accessible in the platform for now. However, for the most up-to-date and accurate information, we recommend utilizing the Search 3.0 dataset.

Q: How often is the Search 3.0 dataset updated?
The Search 3.0 dataset undergoes updates on a daily basis, aligning with our SLA of 72 hours. While it's not truly real-time, our updates ensure that users receive timely data, revealing search behavior from up to two days ago. This frequency enables users to stay informed about the latest trends and developments on the search engine results pages (SERPs), empowering them to make informed decisions based on recent data.

Q: Are there any additional features planned for Search 3.0 in the future?
A: Yes, as we progress through the year, we plan to extend the use of the Search 3.0 dataset to other features within the platform. Keep an eye on our updates for announcements regarding new features and improvements.

Q: Will Search 3.0 include paid clicks? If so, when?
A: Absolutely. Paid data will be gradually added to all pages throughout Q2-Q3 2024.
