For a small Google rank tracker, start with Serper’s 2,500 free queries, then compare its prepaid cost with DataForSEO before paying. Serper is simpler for immediate Google requests, while DataForSEO is cheaper for large queued jobs at its standard rate of $0.60 per 1,000 SERPs. Prices checked November 11, 2026.
Your first task is to define the request, not pick a brand. Decide whether you need Google only, how many searches you will run, how quickly results must return, which location and device matter, and whether you need parsed JSON, HTML, CSV, Markdown or webhooks.
Key takeaways
- Use Serper for a small Google-only test, with 2,500 one-time free queries.
- Use DataForSEO when queued processing and low per-request cost matter more than immediate results.
- Compare billing units carefully because one Google request may cost several credits.
- Confirm
gl,hl,lr, country, city, ZIP code, coordinates and device settings before paying. - Check retention, failed-request billing, credit expiry, renewal and refund terms for the exact plan.
What do you need from a Google SERP API?
You need an API that removes the work of running browsers, proxies and parsers while returning the fields your site or rank tracker can use. A basic organic-rank request usually needs the keyword, Google country, language, location, device, result depth, destination URL and ranking position.
DataForSEO’s Google Organic endpoint defaults to 10 results and accepts language, location, device and depth parameters. It supports desktop and mobile results, plus standard, priority and live processing. Standard processing is cheaper but queued, while live processing costs more when you need an immediate answer.
Your choice changes with the job. One-time testing can use a free allowance. Nightly tracking needs predictable credits, stable pagination and a clear rule for whether a second page costs extra. Local SEO needs city, ZIP code or coordinates, and a search in a second language needs both a location and a language setting.
Before adding funds, write down these requirements:
- Google only, or Google plus Bing, YouTube, Maps, Shopping or other engines.
- Occasional lookups, nightly tracking or millions of searches.
- Immediate responses, a few seconds or queued batch processing.
- Country, language, city, ZIP code, coordinates and device.
- JSON, HTML, CSV, Markdown or webhooks.
Then run the same small query set through two or three free allowances. Compare the returned fields and confirm that the URLs resolve to the final destination. A November 2026 independent comparison reported that Google goto links were unresolved in many responses, with the share changing by provider, country and date. A rank tracker should check URL resolution instead of assuming every returned link is final.
Which providers cost least at small and large volumes?
If you are testing a few hundred queries, Serper is the most practical low-cost starting point. It advertises 2,500 free queries without a credit card. After that, its $50 Starter pack provides 50,000 credits, equal to $1 per 1,000 queries. The credits are prepaid, not monthly, and remain valid for six months.
DataForSEO starts with a $1 trial credit and a free sandbox. Its standard SERP rate is $0.60 per 1,000, so 100,000 standard SERPs cost $60. The minimum top-up is $50, there is no recurring subscription, and the balance does not expire. The tradeoff is timing. Standard work is asynchronous and can take about five minutes on average. Live processing costs more.
The main published paid terms are:
Prices and terms in the table were checked November 11, 2026. ScrapingBee is not directly comparable with per-search APIs because a Google request uses 10 credits in light mode or 15 credits in normal mode. Oxylabs also separates Google non-JavaScript and JavaScript pricing, with published starting rates of $1 and $1.35 per 1,000 results. Confirm the current subscription minimum, Google result definition and renewal amount with Oxylabs before purchase.
Bright Data advertises 5,000 free monthly requests and pay-as-you-go pricing from $1.50 per 1,000, with higher-volume rates from $1 per 1,000. ValueSERP gives 100 free searches, while SearchAPI gives 100 free requests. Zenserp lists 50 free searches per month. Google’s Custom Search JSON API is unavailable to new customers and is scheduled for discontinuation on January 1, 2027.
For a first trial, choose Serper if you want immediate Google results and can use the credits within six months. Choose DataForSEO if you can queue work and expect a large volume. Before funding either account, confirm the minimum balance and the exact Google endpoint you will call.
How do DataForSEO, Serper and SerpApi compare?
DataForSEO fits a rank tracker that can submit work in batches and wait for results. Its standard queue has the lowest published large-volume rate among these three, but live processing costs more. Search operators such as site: can multiply the base task price by five, so calculate the exact credit cost for the endpoint, depth and operators you plan to use.
Serper fits a developer who wants a direct Google request with structured JSON. Its free allowance is larger than SerpApi’s recurring free plan, and its paid entry pack costs $1 per 1,000 credits. Serper publishes throughput of 50 queries per second on Starter, 100 on Standard, 200 on Scale and 300 on Ultimate. Purchased credits expire after six months. Prices checked November 11, 2026.
SerpApi costs more at the entry level, but its product range is broader. It supports Google Search, Maps, Images, Shopping, News, Finance, Flights, Hotels, Scholar, Jobs, AI Mode and other engines and verticals. Its Starter plan is $25 per month for 1,000 searches, while the listed Cloud 1M plan is $3.75 per 1,000.
SerpApi counts one successful search whether the response contains 100 results or an empty result set. Cached, failed and errored searches do not count. It also provides a recurring 250-search free plan, a documented 31-day standard retention period and an Enterprise ZeroTrace option.
The conditional pick is straightforward. Choose Serper for Google-only synchronous requests and a low initial payment. Choose DataForSEO for queued rank tracking and low unit cost. Choose SerpApi when vertical coverage, recurring free usage or its documented legal protections justify the higher subscription.
For the wider decision, compare the DataForSEO and SerpApi costs for your search volume. If your real need is keyword volume, backlinks or competitive SEO data, compare pay-per-request SEO data with a monthly SEO tool.
What do free credits, minimum payments and renewals really cost?
Free credits are not the same as a free trial or a money-back window. Serper’s 2,500 queries are a one-time credit grant. SerpApi’s 250 searches renew monthly on its free plan. DataForSEO’s $1 credit and sandbox support testing. ScrapingBee’s 1,000 credits expire after one month and do not roll over. Prices checked November 11, 2026.
The payment model affects your risk. DataForSEO needs a $50 top-up but has no subscription and no balance expiry. Serper needs a $50 prepaid pack, and those credits expire after six months. SerpApi, ScrapingBee, Zenserp and SearchAPI renew automatically on their selected billing cycle. SearchAPI’s Developer plan is $40 per month for 10,000 searches, and its paid plans renew in advance.
Refund rules also differ. SerpApi allows a full refund within seven days unless more than 20% of searches have been used. Serper allows a full refund within seven days unless more than 20% of credits have been used. SearchAPI allows a full refund within 10 days unless more than 25% of searches have been used. SearchAPI cancellation stops the next renewal but does not prorate unused searches.
Before selecting annual billing or adding paid funds, confirm the renewal interval, renewal amount, minimum funded balance and refund policy for the exact plan. For ValueSERP, Zenserp, Oxylabs and ScrapingBee, request the current plan terms where the public price does not state the complete renewal or refund position.
How do location, language and SERP features change the choice?
A localized result is not created by changing one country code. You may need a country, language, document-language rule, city, ZIP code, coordinates, Google domain and device that match the audience you are measuring.
SerpApi supports hl=es, hl=es-419 and country-specific values such as es-us, es-mx, es-es, es-pr, es-ar, es-co and es-ve. It also supports country, city and coordinate targeting through gl, location, uule, lat, lon and radius.
DataForSEO accepts Google language codes and names, location codes, location names and coordinates. ValueSERP separates interface language through hl, document language through lr, country through gl, and Google domain controls. SearchAPI supports gl, hl, lr, canonical locations, ZIP codes, coordinates and Google domain controls.
For a US audience that searches in Spanish, start with a US location and a language parameter such as gl=us and hl=es-us or hl=es-419. Then compare the returned results with the audience, city and device you intend to measure. ScrapingBee supports the United States and Mexico, desktop or mobile selection, coordinates and radius, but its public Google documentation does not expose the same Spanish-language matrix as SerpApi or ValueSERP.
The endpoint matters as much as the locale. A standard rank tracker needs organic positions, URLs, pagination, location and device. A local SEO product may need Maps and place reviews. SerpApi, Bright Data, ScrapingBee, ValueSERP and Zenserp document several Google verticals, while DataForSEO’s strength is task-based SEO data.
Confirm the exact gl, hl, lr, country, city, ZIP code and device combination in the provider’s location documentation before purchase.
How do billing units, limits and failed requests affect the bill?
A request, result, record, credit and gigabyte are different billing units. ScrapingBee charges 10 credits for a light Google request and 15 for a normal request. JavaScript rendering, premium proxies and AI extraction can raise the credit cost. A cheaper headline rate may therefore cost more for the response your application needs.
DataForSEO charges according to task type and result depth. SerpApi charges one search regardless of result count, while Serper deducts credits after successful responses and stops requests when the balance reaches zero. Bright Data, ValueSERP, Zenserp and SearchAPI describe successful-request billing. SearchAPI also limits use to 20% of plan credits per hour.
ScrapingBee says monthly credits expire and do not roll over. Its successful 200, 404 and 410 responses are charged, while failed responses are not. Oxylabs says system errors returning 5xx or 6xx are not charged, while 2xx and 4xx attempts count as successful.
Make a small cost sheet before launch. Include result depth, second-page requests, rendering mode, retry behavior and failed-request rules. Calculate the exact credit cost for the requested Google endpoint and rendering mode, then compare it with the provider’s minimum payment.
What legal and data-retention questions should you answer before launch?
Automated Google access has a policy question separate from the API price. Google Search Central says automated queries for rank checking and other automated access without express permission violate its spam policies and Terms of Service. SerpApi advertises a US Legal Shield for scraping and parsing search-engine data, subject to exclusions, but that does not transfer responsibility for your use of the returned data.
Retention also affects your design. DataForSEO retains standard JSON results for 30 days, does not store live JSON results, and stores HTML results for seven days. SerpApi retains standard search data for 31 days and offers ZeroTrace for Enterprise. SearchAPI offers zero retention as an Enterprise option.
Before subscribing, obtain the provider’s current terms and privacy commitments for the exact endpoint and plan. Confirm whether queries, HTML, JSON, personal data and result URLs are retained, whether commercial use is allowed, and whether the provider’s terms permit your intended use. Confirm those terms before adding paid funds.
Which provider should you try next, and why?
Try Serper first if your test is Google-only, synchronous and under a few thousand queries. Its free allowance makes it easy to compare fields without a card, but plan around the six-month credit expiry.
Try DataForSEO next if your work can run in a queue or you expect 100,000 or more standard SERPs. Its $50 minimum top-up and $0.60 per 1,000 standard rate are attractive, but live work and deeper results change the cost. The DataForSEO pay-as-you-go review is the next useful step before funding an account. Prices checked November 11, 2026.
Choose SerpApi when you need many Google verticals, recurring free usage or a documented ZeroTrace option. Choose SearchAPI when its $40 monthly entry plan, successful-request billing and Google fields fit your application. In every case, compare the exact endpoint and returned fields for the intended query before committing to a provider.

Why is Google suing SerpApi?
Google filed suit in December 2025, alleging that SerpApi bypassed SearchGuard and scraped copyrighted material appearing in Google Search results. Google’s announcement says the alleged conduct involved bypassing technical protections and reselling content licensed from other parties.
What are good alternatives to DataForSEO?
Serper fits Google-only synchronous requests, Bright Data fits broad geographic targeting and multiple engines, and SerpApi fits Google verticals and non-Google engines. ValueSERP and SearchAPI are simpler Google-focused choices, while Oxylabs and ScrapingBee use result- or credit-based billing across broader scraping products.
Do failed SERP requests cost credits?
Many providers document successful-request billing. SerpApi, Serper, Bright Data, ValueSERP, Zenserp, SearchAPI and DataForSEO say failed or unreturned work is not charged under their stated rules. ScrapingBee and Oxylabs use specific response-code rules, so confirm the exact endpoint before estimating retries.
Do SERP API credits expire?

Can a SERP API return Spanish results for a US city?
Yes, several providers support separate country and language parameters. A US Spanish-language request may use gl=us with hl=es-us or hl=es-419, plus a city, ZIP code or coordinate setting when supported. Confirm the exact location and device combination in the provider’s documentation.
