Receiving and handing over a website SEO project seems to be a good first step to save time and inherit results. But in reality, this is one of the most potentially risky periods for businesses. If you don't check carefully, you may have to "hold on" to bad legacies from the previous SEO team, leading to a drop in rankings, loss of traffic, and even affecting brand reputation.
In this article, we will analyze in detail the biggest risks when taking on an SEO project, along with practical case studies and solutions. This is also the perspective that Tan Phat Digital has drawn from the implementation process for many customers in the following industries: e-commerce, education, real estate and B2B services.
I. Why is the SEO project handover phase "sensitive"?
SEO is not like running ads, you can control it immediately by turning it off or on. SEO is a long-term cumulative process, including onpage, offpage and entity signals. When handing over the project, you not only receive a website, but also "inherit" the entire previous SEO history, from backlink profile, content, to technical configuration files.
This means:
If the previous SEO team did well → you have a foundation to develop faster.
If the previous SEO team did wrong → it will take you many months (or even years) to overcome the consequences.
Actual cases from the Vietnamese market show that many businesses lost 80% of their traffic after just 2 months of receiving the project because they did not check carefully at the handover stage.
II. 6 Common risks when receiving and handing over SEO projects
1. Website has been Penaltyed by Google but not declared
One of the most dangerous "ticking bombs" is a website that has been penalized before. There are two common types:
Manual Action (Manual Penalty): Due to the previous SEO team spamming backlinks, keyword stuffing, cloaking...
Algorithmic Penalty (Algorithmic Penalty): Due to core update, Penguin, Panda.
Many times the old SEO team does not say, or intentionally hides it. By the time you take over, site traffic has been inhibited.
Actual case:
A furniture company in Hanoi received the website from the old SEO agency. After 2 months, the main keyword dropped significantly from the top. Checking Google Search Console, we discovered that the site had been hit with Manual Action because of unnatural links. Removing and disavowing backlinks takes nearly 4 months to partially recover.
How to handle handover:
Request full Search Console permissions.
Check the Manual Action tab.
Compare traffic timeline in Google Analytics to see if there are any unusual fluctuations.
2. Poor quality backlink profile
Backlinks used to be the "backbone" of SEO, but were also the biggest risk when handing over the project. Many old SEO teams use PBNs, spam forums, and junk links to speed up rankings. When you take over, the website may:
Lose rankings after the core update.
Risk of receiving a penalty if Google reviews it.
Difficult to build new quality backlinks due to "bad foundation".
Practical example:
An e-commerce website in the fashion field when handed over to Tan Phat Digital Up to 70% of backlinks come from foreign junk sites, the anchor text is full of exact keywords. After the audit, the team disavowed nearly 500 domains and rebuilt the link building strategy with guest posts in industry newspapers and specialized blogs. After 6 months, organic traffic gradually recovered.
3. Duplicate or "spin" content
A common mistake is that SEO teams first mass-produce content by "spinning" (using a text rotation tool). Result:
Website has hundreds of similar articles, low value.
Google rates poor quality, affecting E-E-A-T.
Risk of being removed from the index.
Case study:
An educational enterprise takes over a website with 300 blog articles. After checking with Copyscape, it was discovered that more than 60% of the content was copy-pasted from other sites. After deleting and rewriting, traffic decreased sharply in the first 3 months, but after that the growth was more stable and sustainable.
Solution:
Audit all content.
Delete or noindex poor quality articles.
Invest in in-depth content with research value.
4. Missing critical data and access
A "headache" when handing over an SEO project is that the old team does not provide enough rights:
Google Analytics, Google Tag Manager.
Google Search Console.
Keyword research tools, rank tracking.
File robots.txt, sitemap.xml.
When data is lacking, you cannot analyze history. SEO, also not knowing the previous strategy.
For example:
When a real estate company takes over the website, it only receives a WordPress username. No analytics data, no GSC. Result: had to start tracking from scratch, completely losing data from the previous 2 years of SEO.
5. Technical issues are left open
SEO Technical is the "backbone" part but is often overlooked when handing over. Common errors:
Redirect chain (complex redirect chain).
Wrong Canonical → duplicate index.
Poor page loading speed, red Core Web Vitals.
Mobile UX errors but not yet fixed.
If you don't audit carefully, you can spend months just to fix the "legacy" this.
6. Brand and Entity Risk
Entity Building is increasingly important. But many old SEO teams do social entities out of sync, using incorrect information (wrong hotline, wrong address). This makes it difficult for Google to identify businesses, affecting TrustRank.
Actual case:
A customer in the tourism industry lost the Top Map Pack because NAP information (Name, Address, Phone) was inconsistent across more than 50 profiles. After resynchronizing all social + Google Business Profile, local search rankings recover.
III. Case study: Receiving SEO project from old agency - Practical lessons
Industry: E-commerce (household appliances).
Status at handover:
Traffic decreased by 70% in 6 months.
Backlink profile contains more than 1,000 spam links from PBN.
Content 40% is copied from another site.
Search Console reports an index error on more than 2,000 URLs.
Tan Phat Digital's actions:
Audit the entire website using Ahrefs + Screaming Frog.
Disavow bad backlinks, build guest posts from industry newspapers.
Delete 500 Spin content articles, rewritten according to topical map clusters.
Fix technical SEO: canonical, sitemap, loading speed.
Rebuild the social entity system in sync with the brand.
Results after 9 months:
Organic traffic increased by 320%.
20 main keywords returned to the top 3.
Online revenue increased 2.5 times compared to the pre-handover period.
IV. Checklist when receiving website SEO project
Requires full rights: Analytics, GSC, GTM, Hosting.
Audit backlink profile (Ahrefs, SEMrush).
Check duplicate content, thin content.
Evaluate technical SEO: speed, index, canonical.
Review entities, synchronize information NAP news.
Compare traffic data with Google updates.
Receiving and handing over the SEO website project is an extremely sensitive period, containing many potential risks. Businesses need to prepare a thorough audit process, do not rush to continue running the campaign without clearly understanding the "heritage" from the old SEO team.
Through practical case studies, it can be seen that: an SEO project when properly "troubleshooted" will recover and grow stronger. With many years of experience handling difficult projects, Tan Phat Digital recommends that all businesses consider the handover period as a "general examination" to promptly detect and handle all risks.
