DataForSEO vs SerpApi: price, engines, AI Overview and speed

DataForSEO costs less per Google search: $0.60 per 1,000 in its standard queue, where results take minutes, and $2.00 live. SerpApi costs $25 to $3.75 per 1,000 on its plans up to a million searches a month, covers more engines, answers synchronously and serves repeated searches from a free cache. Every fact below comes from the two vendors’ own pages, linked and checked 2026-11-11.

Side by side

All cells checked 2026-11-11.

Pricing model

DataForSEO bills per SERP of up to 10 results from a deposited balance. Google Organic is $0.0006 per SERP in the standard queue, $0.0012 priority and $0.002 live (pricing). A depth above 10 bills each further SERP of 10 results (task_post docs). The $50 minimum is a top-up, not a monthly fee.

SerpApi sells a monthly allowance. The rate per 1,000 falls with plan size: $25 on Starter, $15 on Developer, $10 on Production, $7.25 on Searcher, $3.75 on Cloud 1M (pricing). Unused searches are the cost of a plan sized for your peak. A search served from SerpApi’s one-hour cache costs nothing, so workloads that repeat identical searches pay less than the list rate. All checked 2026-11-11.

Engines and verticals

SerpApi’s directory runs to well over a hundred APIs: dozens of Google verticals (Flights, Hotels, Scholar, Patents, Lens, Trends), Yandex, DuckDuckGo, marketplaces and app stores (directory). DataForSEO covers seven search engines with Google types including Organic, Maps, News, Images, AI Mode and Finance, and sells keyword, backlink and on-page data on the same account (SERP API, pricing).

If you need Yandex, Amazon or app stores, SerpApi. If you need SEO datasets next to SERPs, DataForSEO.

AI Overview, AI Mode and assistants

Both return the AI Overview, with different follow-ups for overviews that Google loads after the page:

• SerpApi puts the overview in ai_overview. When Google loads it separately, you get a page_token and must call the Google AI Overview API within 1 minute (AI Overview docs). The page does not say whether that call counts as a search.
• DataForSEO returns an ai_overview item. Without load_async_ai_overview only cached overviews come back; with it, the task costs $0.0006 more, refunded when no overview is present (task_post docs).

For AI Mode, DataForSEO lists $1.20 per 1,000 in the standard queue and $4.00 live (AI Mode pricing). SerpApi’s google_ai_mode engine takes location, uule, gl and hl (AI Mode docs).

Assistants split the two further. DataForSEO’s LLM Scraper says “only ChatGPT and Gemini are supported”, at $1.20 per 1,000 in a standard queue of up to 45 minutes (LLM Scraper pricing). SerpApi lists a Google Gemini API, with no location parameter documented, and a Bing Copilot API (Gemini docs). Neither lists Grok, and SerpApi lists no ChatGPT or Perplexity. All checked 2026-11-11.

Speed: synchronous calls vs queues

SerpApi holds the connection open until the results arrive. async=true returns at once, and you collect the result from the Searches Archive API; its docs mention no webhooks. Ludicrous Speed costs 2x the base price and Ludicrous Speed Max 4x (pricing, Search API docs). Each plan also caps searches per hour, from 200 on Starter to 20,000 on Searcher.

DataForSEO prices speed directly. A Google Organic SERP takes about 5 minutes on average in the standard queue, up to 1 minute in priority and up to 6 seconds live (SERP API). Queued tasks go 100 to a POST and come back by postback_url (gzip-compressed) or a pingback_url notice (task_post docs). All checked 2026-11-11.

A nightly rank run suits DataForSEO’s standard queue. An interactive lookup suits SerpApi or DataForSEO live.

Free tier

SerpApi’s free plan is 250 searches a month at 50 an hour. DataForSEO gives new accounts a $1 credit and no card is required; at $0.0006 per standard SERP that is about 1,666 Google SERPs (SERP API). Checked 2026-11-11.

Which to pick

• Bulk rank tracking that can wait minutes: DataForSEO standard queue.
• Interactive lookups across many engines and verticals: SerpApi.
• Keyword and backlink data on the same bill: DataForSEO.
• Repeated identical searches within an hour: SerpApi, for the free cache.
• ChatGPT answers next to Google results: DataForSEO, of these two.

Where AnswerLine fits

Of the two, only DataForSEO returns ChatGPT answers, and neither lists Grok or the answer perplexity.ai shows. AnswerLine returns what people see in ChatGPT, Gemini, Perplexity, Copilot and Grok, plus Google Search with the AI Overview, Google AI Mode and Google News, under one key and one prepaid balance topped up from $1. A synchronous call and an async task cost the same, and batches of up to 500 tasks report to signed webhooks. Google Search is $1.00–$1.50 per 1,000 across tiers, plus $0.71 per 1,000 for an AI Overview when Google shows one.

It covers fewer search engines than either: no Bing, Yahoo, Baidu or Yandex, and no SEO datasets. Its one-to-one comparisons are DataForSEO vs AnswerLine and SerpApi vs AnswerLine. For more vendors, see DataForSEO alternatives and SerpApi alternatives.
