Proxies for Key Collector from a datacenter pool of IPv4 and SOCKS5 for keyword research. Rotation spreads queries to Yandex and Google across the proxy pool, so collection stays stable. Unlimited traffic, 200+ countries. Free trial up to 2 hours.
Key Collector is a tool for building a semantic core: keywords and their frequencies from Yandex Wordstat, search suggestions and results. It is a core tool for SEO specialists and site owners preparing semantics.
The problem is that with queries from a single IP the search engine quickly applies rate limits and shows a captcha, collection stops within the first hundred queries. Proxies spread queries across different addresses, so collection is not capped by one IP.
Datacenter proxies fit this optimally: collecting frequencies and suggestions is technical parsing. The more addresses in use, the higher the speed and the lower the rate per IP.
Key Collector accepts proxy lists in its settings:
The more proxy addresses are used, the more stable the collection and the fewer captchas appear.
| Parameter | Value |
|---|---|
| List format | IP:PORT is the main one, as a proxy list in the field. IP:PORT:LOGIN:PASS is the second option |
| Where to paste | Key Collector settings, the network and proxy section |
| Protocol | SOCKS5 or HTTP, picked in the same place |
| Check before collection | Switched on in the same Key Collector settings |
| Frequency collection | The more addresses in play, the steadier Wordstat pulls run |
| Phrase volume | Unlimited traffic: large lists and regular rank tracking are not metered |
| Addresses live | 12,000 IPs, rotation runs automatically inside the proxy pool |
| Connection | Bind your IP in the dashboard for the IP:PORT format |
| Try before paying | Free test up to 2 hours |
A pool of 12,000 addresses spreads Wordstat and suggestion requests across different IPs.
It is easier to count from the number of search engine requests than from the number of phrases. Pulling frequencies, parsing suggestions and collecting results are different requests, and one phrase can produce several calls.
Then the rate limit comes in. Search engines react to the density of requests from a proxy address, so the ceiling is set by the safe rhythm per IP. Total speed comes from multiplying that rhythm by the number of proxy addresses in the proxy pool.
The practical order: find the rate at which checks do not appear, then divide the volume you need by that rate to get the number of addresses. Raising threads inside Key Collector only makes sense once the proxy pool can serve them.
A proxy connection refusal almost always comes down to four causes, and checking them in this order saves time. First: the wrong proxy type is selected, HTTP where SOCKS5 is needed or the other way round. Second: the port does not match the one issued.
The third cause sits in the format. If the proxy list is issued as IP:PORT with no login, access works by binding, and requests only go through from the proxy address you registered. Changing machine, network or outbound interface returns a refusal on a perfectly working list.
Fourth: a typo in the login or password, most often a trailing space picked up when copying the string. Check separately that Key Collector actually routes traffic through the proxy: a connection is confirmed by the source address on an IP test service.
Address switching is configured in two places and mixing them up causes trouble. The first is the proxy pool side: the proxy address changes on its own by schedule or per request, and Key Collector needs to do nothing. The second is the software side: you feed different strings from the proxy list to different tasks yourself.
The first option suits uniform work where no state is held between requests. The list is connected once and new proxy addresses arrive automatically, with no intervention needed.
The second option is what you need when collection runs in long queues and the rate to the search engine has to stay controlled. The address is then pinned explicitly and you decide when to change it: after a cycle finishes, after a number of processed items, or on a timer.
Running both modes on one task is usually harmful. If the proxy pool rotates on its own while the software cycles through the proxy list in parallel, behaviour becomes unpredictable and some requests leave from addresses you did not intend.
The base rule: load has to fall evenly across the proxy pool, otherwise some addresses burn out ahead of the rest. So it is better to assign projects to addresses deliberately than to let the software grab whichever comes first.
When tasks differ in weight, count by intensity. One heavy process can produce more requests than five light ones, and it makes sense to give it dedicated addresses so it does not crowd the others.
Keeping a small reserve of addresses that are not permanently occupied pays off. It comes in useful when part of the proxy pool starts meeting checks: you move the affected tasks onto fresh proxy addresses without stopping everything.
And finally, record which task ran from which address. Without that, when refusals appear there is no way to tell whether the cause is a specific address, the task settings or the platform itself.
Proxies for Key Collector are needed at almost every stage of semantic work:
A datacenter pool is exactly what you need here: this is technical data collection, and datacenter proxies fit it best.
The datacenter pool means stable fast addresses and automatic rotation: queries spread across 12,000 IPs, the rate per address is lower, and captchas appear less often.
Traffic is unlimited on all packages, important on large semantic projects with tens or hundreds of thousands of phrases. The pool covers 200+ countries if you collect regional frequencies.
SOCKS5 and HTTP are in the package, with login/password or IP authorization. Key Collector works with both without extra setup.
I collect semantics in batches of 50-100k phrases. On my own IP I drowned in captcha, on the proxy pool it runs smoothly. Exactly what I needed.
Took the trial before paying and ran my Key Collector project, the speed was fine. Unlimited traffic for frequencies is just right.
I track positions and frequencies regularly. Stable, no surprises, support is on Telegram.
Before you pay we offer a free trial up to 2 hours. Run your Key Collector project on the proxy pool and check the speed of frequency collection.
From a single IP the search engine applies rate limits and a captcha within the first hundred queries. Proxies spread queries across the proxy pool, so keyword collection stays stable.
The more addresses, the higher the speed and the lower the query rate per IP. The package gives access to a proxy pool of 12,000 addresses with rotation.
They fit optimally. Collecting frequencies and suggestions is technical parsing, and a datacenter pool fits it best.
Key Collector works over HTTP and SOCKS5, both are in the package, switch in settings.
The pool covers 200+ countries, so you can pick addresses for the region you collect.
No, traffic is unlimited on all packages, the volume of collected semantics is not capped.
A free trial is available up to 2 hours. Run your Key Collector project on the proxy pool and check collection speed before you pay.
