Based on the fact that Google Ads accounts for only about 1/6 of the site traffic that SEO (organic) brings in, and since both traffic sources are targeting the same search terms on the same platform, it seems reasonable to expect that organic traffic would account for significantly more calls than Google Ads. However, since some organic searches my be for more informational terms, let’s conservatively extrapolate that organic leads are equal to leads from Google Ads.
If our (conservative) assumptions are correct, we’re looking at a campaign generating approximately 5-10 calls per month from Google Maps, 15 calls per month from Google Ads, and 15 calls per month from organic traffic for a total of 35-40 additional calls per month.
