Changing SEO agency should not mean losing the rankings you have already achieved. The risk arises when the change is combined with technical modifications, lost access, content removal, URL changes or rushed decisions without first documenting what is working.
At Ventia Group, an SEO agency in Barcelona specialising in business-focused SEO strategies, we take on projects from other providers and always start with the same premise: before changing anything, you need to understand what is worth keeping. The transition is not about deleting the previous work and starting from scratch, but about auditing it, protecting useful assets and building a better strategy on that foundation.
If you want to change SEO agency without losing rankings: regain control of all your accounts, document the URLs and queries already generating traffic, review redirects and technical configuration, retain historical data, request the strategy and actions carried out, and avoid large-scale changes during the first few days. At Ventia Group, we use this information to design an orderly transition before implementing new actions.
Will changing SEO agency cause a drop in Google?
Not necessarily.
Are you thinking about changing SEO agency but worried about losing everything you have built in Google? At Ventia Group, we analyse your current situation and design a secure transition, with no unpleasant surprises or traffic drops.
Google does not know, nor does it need to know, which agency manages a website. The search engine responds to changes made to the site, its URLs, content, links, technical availability and other signals.
Therefore, changing provider while properly maintaining the website and its assets should not in itself cause a loss of rankings.
The problem arises when changing agency coincides with actions such as:
- Changing URLs without correctly mapping their destinations.
- Removing pages that generated traffic or links.
- Modifying titles, content or architecture without analysing previous performance.
- Losing robots, canonical, hreflang or structured data configurations.
- Removing existing redirects without understanding their purpose.
- Losing access to Search Console, Analytics, Business Profile, domain or hosting.
At Ventia Group, we treat an agency change as a transition of knowledge and control, not as a technical migration unless the website, domain, hosting or URLs are actually going to be changed.
When it makes sense to change SEO agency
There is no three-, six- or twelve-month period that automatically determines whether an agency is working well or poorly.
A website may go through periods of stability or decline due to competition, technical changes, seasonality, demand, Google updates or internal business decisions.
What should concern you is being unable to get a reasoned explanation.
Signs that justify reviewing the relationship
- You do not know what strategy is being implemented.
- You do not have sufficient access to your own tools and assets.
- Reports show metrics, but no one explains what they mean for the business.
- Content is published without a clear architecture or search intent.
- Major technical changes are made without documentation.
- The agency promises specific rankings that it cannot control.
- Data shows problems and the strategy does not adapt.
- There is no connection between the SEO work and the services you want to sell.
At Ventia Group, we analyse these points before recommending an immediate break. Sometimes the problem is communication or measurement; other times, the project genuinely needs a new strategy.
Step 1: create an SEO snapshot before touching anything
Before the handover, it is advisable to document how the website is performing at that point.
There is no need to turn this phase into an endless report. The important thing is to retain the data that will make it possible to distinguish normal performance changes from a problem caused by later changes.
What we recommend saving
- Main queries in Google Search Console.
- Landing pages with the most organic clicks and impressions.
- Relevant conversions and analytics events.
- URLs capturing important commercial searches.
- Indexing status.
- Existing redirects.
- Canonicals, robots and sitemaps.
- Relevant backlinks and referring domains.
- Content map and service pages.
- Business Profile configuration if local SEO is involved.
At Ventia Group, we use this snapshot as a baseline to identify which assets should not be put at risk and which areas require a more in-depth review.
Step 2: regain control of accounts and assets
The business should avoid being permanently dependent on a provider's personal account to access its essential assets.
In Search Console, owners and users have different permission levels. An owner has control to add or remove users and manage the property.
For this reason, we recommend checking that the business retains an appropriate level of access and is not exclusively dependent on the outgoing agency's account.
Access checklist
| Asset | What to check |
|---|---|
| Search Console | That the business has ownership or sufficient access and knows how the domain is verified |
| Google Analytics | That there is a corporate account with the necessary administrative permissions |
| Business Profile | That the business retains ownership and can manage owners/managers |
| Domain | Access to the registrar and ownership details |
| DNS | Access to the platform managing the DNS zone |
| Hosting | Credentials and contractual control |
| CMS | Its own administrator user account |
| Tag Manager | Sufficient permissions for the business |
| SEO tools | Useful exports or historical data where they belong to the project |
We do not recommend asking for “the agency's passwords”. Where a platform allows owners, users, administrators or roles, the transition should be handled through permissions and access transfer, avoiding the sharing of personal credentials.
Step 3: retrieve documentation from the previous work
Not everything an agency has done will be visible in Search Console.
Before ending the relationship, it is advisable to request, where available:
- Keyword map.
- Content plan.
- Previous technical audits.
- List of implemented changes.
- Redirect map.
- Migration documentation.
- Links acquired or off-page actions carried out.
- Historical reports.
- Backlog of pending tasks.
- Relevant technical decisions and their rationale.
Ownership and delivery of materials should be reviewed in accordance with the existing contract. It is not correct to assume that every internal agency document or asset automatically belongs to the client.
At Ventia Group, we recommend that future contracts make clear from the outset which assets, content, accounts and deliverables belong to each party.
Step 4: audit before making changes
A new agency needs to resist the temptation to demonstrate activity by changing everything during the first week.
Before implementation, at Ventia Group we review three areas.
What is working
URLs generating business, content with visibility, relevant links, pages capturing transactional searches and useful technical configurations.
What is limiting growth
Cannibalisation, architecture, insufficient content, indexing, technical issues, incorrect search intent or the absence of required pages.
What can be improved without putting established assets at risk
We prioritise actions according to expected impact and risk. A high-performing URL is not “off limits” forever, but any modification must have a reason and be measured afterwards.
Step 5: take care with URL changes
This is one of the most sensitive points.
Google recommends preparing a mapping between old URLs and their new destinations when there is a site move or structural change, and using redirects to indicate the new location.
If a URL changes without an appropriate solution, users and Google may encounter an error or a page other than the one expected.
Before changing slugs or architecture
- Export the current URLs.
- Identify those receiving traffic and links.
- Define an equivalent destination where one exists.
- Prepare the redirect map.
- Update internal links.
- Review canonicals and sitemap.
- Monitor errors after the change.
At Ventia Group, we do not change URLs simply because we “like” another version better. The expected benefit must justify the risk and cost of the change.
Step 6: do not remove content simply because it has low traffic
A URL with few clicks may serve other purposes within the site: internal linking, covering a specific intent, supporting a commercial page or attracting highly specific queries.
Before removing, consolidating or redirecting content, we review:
- Impressions and queries.
- External links.
- Internal links.
- Conversions.
- Search intent.
- Overlap with other pages.
- Content freshness and usefulness.
We then decide whether to retain, update, merge, redirect or remove it.
Step 7: review link building without fearing “toxic links”
Changing agency is a good time to review which off-page actions have been carried out.
Google considers link spam to be practices created mainly to manipulate rankings, including certain exchanges, automated activity or buying and selling links for that purpose.
However, we do not recommend turning every low-quality link into a crisis. First, its origin, pattern and relevance need to be understood.
At Ventia Group, we review the link profile as part of the overall diagnosis and prioritise an authority strategy aligned with the sector and project.
Step 8: protect local SEO during the agency change
If your business depends on local customers, the Google Business Profile is a critical asset.
Every day you postpone the change is another day your competitors keep moving ahead. Tell us where you are now and we will show you how to get where you want to be, with a personalised SEO strategy and without risking your current rankings.
Google allows owners and managers to be managed, and primary ownership to be transferred to another owner or manager when the profile requirements are met.
Before ending the relationship with the previous agency, check:
- Who is listed as the primary owner.
- Which owners and managers exist.
- That the business's corporate account retains access.
- That the address, phone number, opening hours and categories are correct.
- That reviews and historical information remain on the profile.
At Ventia Group, we review this as part of client transitions involving a local strategy in Barcelona or other cities.
Is it necessary to overlap the two agencies?
It can be useful, but there is no universal duration.
For some projects, a well-organised documentary handover will be enough. For others, especially where there are ongoing developments, migrations, content campaigns or many technical dependencies, it may be advisable for both providers to overlap for a limited period.
What matters is not whether it is exactly two or three weeks. What matters is that the new agency has the necessary information before taking on critical tasks.
How long does SEO take to stabilise after changing agency?
If only the provider changes and the website remains technically the same, there does not need to be any “recovery” period.
If the new strategy introduces changes, Google may need time to crawl, process and reflect them in its systems. This time varies depending on the type of change, the site and crawl frequency.
This is why we avoid promising fixed scenarios such as “one month if it goes well” or “six months if it goes badly”.
At Ventia Group, we pay particular attention to:
- Clicks and impressions.
- Priority queries.
- Commercial URLs.
- Indexing.
- Crawl errors.
- Organic conversions.
- Significant changes in visibility.
Which tools are really needed during the handover
There is no list of software that every agency must use.
Google Search Console is particularly valuable because it provides direct data from Google Search and makes it possible to review performance and indexing.
From there, analytics, crawling, rank-tracking or link-analysis tools can be used depending on the project.
At Ventia Group, we prefer each tool to answer a specific question. More software does not necessarily mean better decisions.
Core Web Vitals during an SEO transition
It is advisable to record performance before and after major technical changes to detect regressions.
Core Web Vitals are part of the signals related to page experience, but they should not be treated as an isolated score capable of explaining a rise or fall on its own.
At Ventia Group, we review them when they are relevant to the project, especially if the provider change coincides with template, hosting, JavaScript or infrastructure modifications.
How to communicate your departure to the previous agency
A professional transition starts by reviewing the contract and respecting the agreed terms and notice periods.
Communication can be direct and straightforward: notify them of the end of the relationship, request the handover schedule and ask for the relevant access and deliverables.
It is advisable to centralise the following in writing:
- End date.
- People responsible on each side.
- Access that needs to be transferred.
- Outstanding documentation.
- Work in progress.
- Invoices or commitments linked to external actions.
What a good new SEO agency should do during onboarding
Onboarding a client coming from another agency should be more cautious than onboarding a project starting from scratch.
| Phase | Objective | What we do at Ventia Group |
|---|---|---|
| Control | Ensure access | We review accounts, permissions and assets |
| Initial snapshot | Retain a baseline | We document performance, URLs and configuration |
| Audit | Understand the previous work | We separate what works from what is limiting the project |
| Risk | Avoid unnecessary losses | We identify critical URLs, redirects and configurations |
| Strategy | Define priorities | We design a roadmap based on business and opportunity |
| Measurement | Validate the change | We track visibility, clicks and conversions |
Why choose Ventia Group when changing SEO agency
At Ventia Group, we do not see a change of provider as an excuse to rebuild the entire project.
Our initial priority is to understand what the business has built so far, which assets generate results and which decisions can improve growth without unnecessarily destroying value.
As an SEO agency in Barcelona, we work on local projects and strategies for businesses across Spain, combining:
- SEO audit.
- Technical SEO.
- Website architecture.
- Keyword research.
- Transactional and informational content.
- Local SEO.
- Authority strategy.
- Measurement and monitoring.
If you are looking for a new agency because the project has stalled, because you do not understand what your current provider is doing or because you need a strategy more focused on lead generation, at Ventia Group we can start by analysing the situation before you make irreversible decisions.
Frequently asked questions about changing SEO agency
Can I change SEO agency without losing rankings?
Yes. Changing provider does not in itself cause a loss of rankings. The risk arises if URLs, content, redirects, configurations or assets are changed during the transition without first analysing their function and performance.
Changing SEO agency does not have to be a leap into the unknown. At Ventia Group, we audit your website, review what is already working and build on that foundation so the change becomes an opportunity for growth, not a risk.
What should I ask my SEO agency for before leaving?
It is advisable to recover the access and deliverables that apply under the contract: accounts, strategy documentation, reports, keyword maps, content, redirects, technical work and external actions relevant to the continuity of the project.
Should I give my passwords to the new agency?
Whenever the platform allows it, it is preferable to use users, roles and permissions rather than share personal passwords. Search Console and Google Business Profile, for example, allow owners and users to be managed.
How long does SEO take to stabilise after changing agency?
If only the provider changes and the website remains the same, there does not need to be a recovery period. If technical or content changes are made, Google may take a variable amount of time to crawl and process them.
Is it mandatory to overlap the previous and new agencies?
No. It can be useful for complex projects, but there is no standard duration. What matters is that the new agency has the access, documentation and context needed before taking on critical tasks.
What happens if I want to change URLs during the transition?
A map between old and new URLs should be prepared, the necessary redirects implemented, and internal links, canonicals and sitemap reviewed. Google recommends planning these changes to minimise their impact on Search.
Can Ventia Group review my SEO before I cancel with my agency?
Yes. At Ventia Group, we can analyse the project's current status and help you identify what is working, what risks exist and what strategy we would propose before making changes to the website.
Why choose Ventia Group as your new SEO agency?
At Ventia Group, we approach the transition through auditing, asset protection, technical review, content strategy, local SEO, authority and measurement. Our aim is to retain what already generates value and build a roadmap more focused on qualified visibility and lead generation.
