Most agencies arrive at their proxy setup by accident. The SEO team bought something for rank tracking. The paid media team found something else for checking ads. A strategist signed up for a third tool to pull competitor pricing for a pitch. Three vendors, three integrations, three sets of location codes, three invoices, and no way to answer a simple client question: when our SEO report and our ad report both say “Madrid”, do they mean the same thing?
This is the case for consolidating onto one network. Not because one tool is cheaper, although it often is, but because the three workloads are asking the same underlying question, what does a real user in this market see, and they should be answering it the same way.
Three workloads, three shapes of traffic
The workloads share a need for local vantage points and differ in almost everything else. Understanding the differences is what makes one network work for all three.
SEO monitoring is high volume and lightweight. Many independent queries, each small, each needing a precise location and a device profile, and each one independent of the last. It wants rotation on every request and city-level targeting, because local results change at a granularity finer than a country. The mechanics are in geo-targeted SERP APIs for local SEO.
Ad verification is low volume and heavy. Fewer checks, each a multi-step journey from impression to landing page, often rendered in a browser, and each needing consistent locale signals from start to finish. It wants sticky sessions and coherent device and language settings. The programme design is in verifying ad placements at scale.
Competitive intelligence sits in between. Category walks, paginated result sets, landing pages and offers, each needing internal consistency across a sequence of requests. It wants sticky sessions per walk and modest, steady cadence. Covered in competitive campaign intelligence.
| Workload | Session pattern | Weight per check | Targeting that matters |
|---|---|---|---|
| SEO monitoring | Rotate per request | Light | City and device |
| Ad verification | Sticky per journey | Heavy, often rendered | Country, city, locale consistency |
| Competitive intel | Sticky per walk | Medium | Country, sometimes city |
Why one network beats three
One targeting model. When all three workloads express location the same way, a finding about a client in Madrid means the same thing in the SEO report, the ad report and the competitive deck. With three vendors you are reconciling three definitions of “Madrid” that may not agree, and a client who notices will ask why.
One integration to maintain. Every vendor is a credential format, an error vocabulary, a set of targeting codes and a support relationship. Consolidating removes the work that nobody bills for.
Comparable vantage points. When the SEO team sees a local competitor rising and the paid team sees the same competitor bidding harder in the same city, the two observations came from comparable exits, so they can be put side by side rather than argued over.
One place to understand spend. Residential bandwidth is the cost driver, and it is far easier to forecast when all three workloads are measured in the same unit on the same dashboard. The method is in forecasting residential proxy bandwidth.
With the Shifter gateway, all three workloads use the same endpoint, p.shifter.io:443, and express their differences entirely in the credentials:
# SEO: rotate every request, city-level
customer-USERNAME-country-es-city-madrid:PASSWORD
# Ad verification: one exit for the whole journey
customer-USERNAME-country-es-city-madrid-sid-adv-221-ttl-600:PASSWORD
# Competitive intel: one exit per category walk
customer-USERNAME-country-es-sid-ci-walk-09-ttl-600:PASSWORDOmitting sid gives per-request rotation. Adding it holds one exit, and ttl sets how long. That single difference is what lets one network serve all three shapes of traffic without three configurations.
For the SEO workload specifically, the SERP API is worth considering as an alternative to managing the requests yourself, since it returns structured results with location and device already handled.
Keep clients apart
Consolidating workloads is right. Consolidating clients into one undifferentiated pot is not, for three reasons.
Cost attribution. Clients are billed for work. If every client’s collection runs through one plan, you cannot say what each one cost, and margin by client becomes a guess.
Budget containment. One client’s campaign spike should not consume the allowance another client’s reporting depends on.
Clean offboarding. When a client leaves, their access, their plan and their history should leave with them, without disturbing anyone else’s.
Shifter handles this with Team Workspaces: each client can have its own workspace with its own plans, wallet and invoices, and the agency’s account leads are added as members with one login and a switcher in the sidebar. Plans never cross workspaces, so traffic is never co-mingled. The setup is walked through in sub-accounts and usage tracking for multiple clients, and the feature itself in introducing Team Workspaces.
Record the vantage point in every client deliverable
The practical benefit of one network only lands if the reports show it. Every observation that reaches a client deck should carry the market, the city where relevant, the device profile and the timestamp. Then the three disciplines can be cross-referenced in one conversation, and a disputed number can be traced back to exactly where it was observed.
This is also what separates an agency that reports data from one that can defend it. A client who asks “where did you see that?” should get an answer in seconds.
FAQ
Will one client’s heavy crawling affect another client’s results?
Exits rotate across the pool rather than being assigned to one client, so there is no fixed set of addresses one client can use up. What is shared is conduct: an address pushed too hard against a target is worse for whoever draws it next, so keep every client’s request rates ordinary. Budget is the other shared resource, which is why each client should have its own plan.
Is one network enough for every client in every market?
For most agencies, yes, provided it covers the countries and cities your clients operate in at the granularity your SEO work needs. Check city-level coverage in your top markets before consolidating.
Should the SEO team use proxies or the SERP API?
If the team wants structured results and no request management, the SERP API. If it needs to observe pages the API does not cover, or wants full control, proxies. Many agencies use both.
How do we bill clients for collection?
Give each client its own plan, and bill from that plan’s usage. Usage is tracked per plan in the panel, which is the unit that makes client-level attribution clean.
The bottom line
Agencies run three collection workloads that differ in session pattern, weight and targeting, and share one question: what does a real user in this market see. Answering it with one network and one targeting model makes the three disciplines comparable, removes two integrations, and puts spend in one unit.
Consolidate the workloads, not the clients. Keep each client in its own plan and workspace, record the vantage point in every deliverable, and let the credentials, not the vendor, express the difference between an SEO check and an ad journey. The product itself is on the residential proxies page, with rates on the pricing page.
