While these two metrics may seem similar, they differ in once key aspect.
Share of Search uses the total search volume of the selected keywords and shows a domain's estimated traffic as percentage of the total search volume.
Share of Visibility uses the total estimated traffic of the tracked domains for the selected keywords and shows a domain's estimated traffic as a percentage of the total traffic.
Here is an example:
Keyword | Rank | Domain | Search Volume | CTR% | Est. Clicks |
keyword1 | 1 | 1000 | 37 | 370 | |
keyword1 | 2 | 1000 | 18 | 180 | |
|
|
|
|
|
|
keyword2 | 1 | 800 | 37 | 296 | |
keyword2 | 2 | 800 | 18 | 144 |
Total search volume for these 2 keywords is 1800, while the sum of the estimated traffic is 987.516
Share of Search:
Domain | Total Est. Clicks | Share of Total Search Volume | Share of Search % |
514 | 514 / 1800 = | 29 | |
476 | 476 / 1800 = | 26 |
Visibility Share:
Domain | Total Est. Clicks | Share of Total Clicks (Visibility Share) | Share of Visibility % |
1.com | 514 | 514 / 990 = | 52 |
2.com | 476 | 476 / 990 = | 48 |
