KrispCall – Hyper-Local Landing Pages for Phone Numbers (Area Codes)

Cloud telephony startup KrispCall grew its organic traffic exponentially by leveraging programmatic SEO to create targeted landing pages for phone area codes and virtual numbers. This strategy allowed KrispCall to compete in search with a relatively new site by banking on highly specific queries:

Area Code Pages

In 2023, KrispCall rolled out 535 new pages focused on U.S. telephone area codes. Each page, like “Los Angeles 213 Area Code – Get a 213 Number”, was built from a template containing the area code’s location (city/region), history info, examples of numbers, and a call-to-action to purchase a virtual number in that area via KrispCall. By doing this for hundreds of area codes (covering 80% of all U.S. codes), KrispCall captured searchers looking for specific area code details or wanting a local business number.

This is classic long-tail SEO – few people search “get a 213 area code” compared to “business phone system”, but collectively the traffic is substantial and highly relevant.

Massive Traffic Growth

The impact was dramatic. After launching these pSEO pages, they comprised 82% of KrispCall’s US organic traffic in the following month. Overall, KrispCall’s site traffic surged from virtually zero in April 2021 (only ~154 visits at launch) to over 2 million visits by August 2023, largely thanks to programmatic pages like the area codes. That’s a 1,969% year-over-year increase in organic traffic according to one case study.

Essentially, pSEO gave KrispCall a shortcut to rank for hundreds of niche keywords that together brought in hundreds of thousands of visitors looking exactly for what KrispCall offers (local phone numbers).

Other Programmatic Pages

In addition to area codes, KrispCall likely applied similar tactics for country calling codes (e.g. “How to get a +44 UK number”) and feature pages (like pages for “virtual SMS numbers”, “call recording service” etc. that follow templates). The codeable.io guide notes that KrispCall’s programmatic pages also included non-area-code content – presumably they generated pages for major cities or countries, each with a standardized pitch for obtaining a number there.

By covering telephony-related queries exhaustively, KrispCall built itself into a comprehensive resource, which not only drew traffic but also signaled to users (and Google) that KrispCall is a telephony authority.

Leveraging AIOSEO & WordPress

Technically, KrispCall used tools like AIOSEO’s WordPress plugin to implement this at scale. They could prepare a CSV of area codes with metadata (city, state, code) and auto-generate pages via a WordPress import or custom code. The pages were optimized with schema (LocalBusiness markup, etc.) and internal linking to relevant sections of KrispCall’s site.

The high degree of on-page optimization combined with relatively low competition for these terms meant many of these pages quickly rose to page 1. The success was so notable that WordPress-centric SEO blogs now cite KrispCall as a prime example of pSEO in action. It demonstrates that even a startup in a competitive industry (business communications) can carve out a niche via programmatic content targeting underserved queries.

By capturing interest at the “area code” level, KrispCall not only got traffic but also educated potential customers on why they might need a virtual number – then conveniently offered them one. This strategy delivered both traffic quantity and lead quality, accelerating KrispCall’s growth path.
