How much does keyword gap analysis software cost per month?

Keyword gap analysis tools range from free to about $150 per month, depending on how many sites you track and how many competitors you compare against.

Sohocheq pricing: Free ($0, 1 site), Premium ($29/month, 3 sites, 1 competitor per site), Pro ($79/month, 10 sites, 3 competitors per site), Agency ($149/month, 25 sites, 5 competitors per site). Additional sites are $9/month each, on any plan.

What determines the price?

Three things: how many sites you track, how many competitors you compare per site, and how much history you keep. Sohocheq's free plan includes 7-day history. Premium gets 90 days. Pro gets 1 year. Agency gets unlimited.

Why is some software $99+ and some free?

The expensive tools bundle in a licensed keyword database — search volumes, difficulty scores, CPC estimates. They pay for that data, so you do. Free or low-cost tools (like Sohocheq) skip the licensed database and read public signals instead, which is enough for gap analysis but not for volume forecasting.
