SEO and keyword research toolkit

Should you build your own Semrush?

Switch to Mangools. It costs $26 a month against Semrush’s $117, and Google Search Console is free.

SWITCH

Short answer

Semrush’s SEO plan is $117.33 a month on annual billing ($139.95 monthly), about $4,200 over three years for one user. Mangools gives you keyword research, rank tracking and backlink checks for $26.35 a month. Ahrefs Free and Google Search Console audit your own site for $0. You can’t realistically build this yourself, because search volumes and rankings come from paid data providers.

What you’d build

  • A rank tracker for your keywords using a SERP data API
  • A crawler that flags broken links, missing titles and slow pages
  • Search Console data pulled into one dashboard
  • A keyword list with search volumes from a data provider

Our estimate for a SERP data API and hosting. Keyword and ranking data is billed per request.

What you’d give up

  • Large keyword and backlink databases
  • Competitor traffic and ad research
  • Site audits at scale and content tools
  • AI search and brand visibility tracking

Risks the price doesn’t show

Search dataHigh

Search volumes, rankings and backlinks come from paid data providers, so you rent the data.

Scraping limitsMedium

Scraping Google breaks its terms and gets blocked, and APIs charge per query.

UpkeepMedium

Crawlers and rank trackers need constant tuning as search results change.

When the verdict flips

Switch to BUY if you run SEO for several clients or need deep competitor and backlink research. That’s where Semrush’s databases earn their price.
