How is traffic share calculated?
We keep the top 10,000 keywords from the contributor network and 10,000 keywords from scraping for each site and month. The contributor network data has visits per keyword.
When a user queries one month of keyword data, and the site has more than 10,000 keywords from the contributor network for that month, then the keyword data we have is not 100%.
Is the traffic share taken out of total search volume?
No. Volume is the number of times someone searched for a keyword; bear in mind, however, that not all searches lead to a click of a result: users might either refine their search or just find the information they were looking for within a SERP feature. Traffic Share is taken as a % of all traffic, i.e., every time someone clicked on a result following a search.
Why am I seeing keywords with 0% traffic share?
We complement search traffic per domain with keywords we crawl on the Google Search Engine Results Page (SERP). Even if we don't see traffic from a particular keyword to a domain in our anonymous behavioral data, if the site appears in Google results, we show this data with a traffic share of 0%. This provides our users with more keywords to discover per domain and provides new ideas to optimize their own search strategies.
Search traffic can be higher than search volume due to the fact that an individual can do a single search and then click multiple results.
Additionally, in general, we track traffic across all engines (Google, Yahoo, Bing, etc.), however, our volume metric is specific to Google volume. Therefore, another reason why we might be seeing traffic share data for a keyword, but minimal search volume, is due to the fact that the searches didn't come from Google.
How does Similarweb classify different types of Google search - Google Shopping, Google News, Google Images, Google Maps, Google Videos, etc.?
Google Shopping is classified as 100% Paid Search, while the other search types (News, Maps, Videos, Images) are 100% Organic.
When does keyword volume and cost per click (CPC) get updated?
Volume and CPC come from Google's Adwords API. Google usually releases the data for the previous month on a two-week delay. So you'll usually see the data refresh around the 14th of the following month.
Why do similar keywords have the exact same CPC?
You might find that similar keywords (plurals, for example, like nike vs. nikes) have the exact CPC. This is in line with how Google shares the data with us. They are known to sometimes aggregate certain keywords, but nobody knows the exact algorithm they use.
Why does a keyword’s destination URL change month to month? Is this URL the result of the most clicked on a keyword?
We collect SERP data frequently, so this URL is the most recent landing page we've seen with the highest position, not necessarily the most clicked on.
How is it possible that there are more keywords results when filtering by a specific country than by Worldwide?
We have data for the top 10,000 keyword results per month for each in our database (paid & organic combined) for both worldwide and each individual country. In some cases, the keywords that we show for a specific country that we don't show for worldwide had a lower traffic share, and therefore, they made the cut to be displayed for that country, but not worldwide.
Note: If you take away all filters (except for country) and filter by one month, you can see more than 10,000 results. Here's an explanation of why:
We show keywords (in addition to the original 10,000 from our database) for which we didn't actually see any traffic to the website. You can recognize these keywords because they will have a 0% traffic share.
Also, note that for the 10,000 keywords we do have data for (meaning we detected traffic from them to the website), this will not necessarily translate to exactly 10,000 keywords (with traffic share over 0%). This is because in our database, out of the 10,000 keywords we have data for, some may be duplicates. For example, if the keyword "books" sends traffic to amazon.com, it would appear once in the results. But in our database, it could be listed multiple times because it would be listed once as organic Google, once as PPC Google, once as organic Yahoo, etc. Meaning the keyword "books" would account for 3 out of the 10,000 results in our database but only be shown once.
Why is there a higher percentage of traffic share when summing up the total traffic share when filtering by a word in ‘Keywords’ than for that same word in Keyword Phrases?
In general, based on the methodologies, we would expect the two numbers to be quite close but not perfectly aligned. This is because there's something that can cause the number of Keywords to be higher than the one in Keyword Phrases.
For example, let's say we're analyzing uniqlo.com and looking at:
Filtering the keyword results to include all KWs that contain "shirt."
Looking at the Keyword Phrase "shirt."
Let's say these are all the keywords that we see for “shirt”:
Only the first 3 keywords will be part of the Keyword Phrase "shirt" because the logic which creates a Keyword Phrase looks for individual words; it doesn't look for the string of letters within other words.
Why is there no position ranking for certain organic keywords?
Our position data is a metric we provide to supplement our keyword traffic share data. Because the number of keywords we have data for is so large, we cannot pull the position data (which we get from public sources) for 100% of the keywords for which we have traffic share data. Thus, we have a system that prioritizes a list of keywords to collect position data for.
If you spot a keyword that is missing position data and you'd like us to prioritize this keyword for future months, feel free to add this keyword to a Keyword List, which will automatically add the keyword to our priority list for the coming months!
