An SEO company handles privacy regulations by treating data collection as a constrained activity rather than an unlimited one. Search engine optimization depends on analytics, conversion tracking, and sometimes advertising tags, and all of those touch user data. A competent SEO company configures those tools so they collect what is needed for measurement while respecting consent rules, and it coordinates with your legal advisors rather than acting as one.

Which rules apply

The two most discussed frameworks are the EU General Data Protection Regulation (GDPR) and California’s privacy law, the CCPA as amended by the CPRA. GDPR applies when you handle the personal data of people in the EU, and the related ePrivacy Directive governs the use of cookies and similar technologies. In the United States, a growing number of states have their own comprehensive privacy laws, so the obligations that apply to your site depend on where your visitors are and what data you collect. An SEO company should help you identify which tools on your site collect data, but the determination of which laws apply to your business is something your legal team confirms.

Consent and cookie banners

Most analytics and advertising tags set cookies or use similar identifiers, and under the ePrivacy Directive those generally require opt-in consent before they load. A Consent Management Platform (CMP) displays a cookie banner, records each visitor’s choice, and passes that choice to your tracking tools. An SEO company typically helps select and configure a CMP, places the banner so it loads before tracking tags fire, and verifies that rejecting cookies actually blocks the relevant tags. The wording of the banner and the categories of consent offered are areas where legal review matters, so the SEO company implements the technical side and defers to counsel on the language.

Google Consent Mode

For sites using Google tools, Google Consent Mode is the mechanism that tells Google tags whether a visitor has consented to analytics and advertising data. It works alongside a CMP, not instead of one. An SEO company can set the default consent states, connect Consent Mode to your banner so consent updates are passed through, and test that the signals behave correctly. Consent Mode does not replace the need for a banner or for valid consent; it governs how Google tags respond once consent is or is not given.

Privacy-respecting analytics configuration

Beyond consent, an SEO company configures analytics to limit unnecessary data collection. Google Analytics 4, for example, anonymizes IP addresses automatically; it uses them briefly to estimate location and then discards them rather than storing them. The SEO company can also set shorter data retention periods, avoid sending personal data such as names or email addresses into analytics, turn off features that are not needed, and disable or restrict data sharing settings. Where appropriate, some businesses choose privacy-focused analytics platforms that collect less data by design. These choices reduce the amount of personal data your SEO activity touches in the first place.

What an SEO company should and should not do

An SEO company should map the tracking tools on your site, configure them to honor consent, document how they are set up, and test that the setup works. It should not draft your privacy policy, decide your lawful basis for processing, or tell you that a configuration makes you compliant. Compliance is a legal conclusion, and technical setup is only one input to it.

Coordination, not legal advice

The practical answer is that an SEO company manages the technical layer and works with whoever owns privacy at your organization. Analytics and advertising setup should match what your privacy policy says and what your CMP offers, and that alignment only happens when SEO, marketing, and legal review the same plan. When you ask how an SEO company handles privacy regulations, expect a partner who builds and tests a consent-aware tracking setup, explains the trade-offs in measurement, and points you to legal counsel for the questions that are genuinely legal ones.

Some can, but many general SEO companies cannot, or do not offer it as a core service. Baidu optimization is its own discipline. It serves businesses that want visibility with users in mainland China, where Baidu is the leading search engine and Google has very limited reach because it is largely inaccessible behind China’s content filtering. If reaching Chinese consumers is part of your goals, ask any prospective agency directly whether Baidu work is something they actually do, rather than assuming that general SEO skills transfer.

Why Baidu is a separate discipline

Optimizing for Baidu is not the same as adjusting a Google strategy. The platform has different technical requirements, ranking behavior, and compliance rules. An agency that is strong at Google SEO may have little or no practical experience with any of these.

The most significant difference is regulatory. To rank well on Baidu, a website typically needs an ICP filing, which is a registration that ties the site to a responsible legal entity in China. Foreign companies generally cannot file for this directly and need a Chinese business entity or an authorized local partner. The filing process takes time and involves paperwork most Western agencies are not set up to handle.

Hosting is the next major factor. Baidu favors websites hosted on servers inside mainland China, or at least delivered through infrastructure close to the country. Sites hosted only overseas tend to load slowly for Chinese users, get crawled less often, and can rank lower as a result. Moving or duplicating hosting into China is usually tied to the ICP requirement above.

Content also has to be built for the market. Baidu prioritizes content written in simplified Chinese, and it tends to favor Chinese-language pages even for some queries that are not in Chinese. The content needs to read as though a native speaker wrote it. Machine translation generally does not perform well. This means real localization, not a quick translation pass.

The technical and on-page approach differs too. Baidu has its own webmaster tools for submitting URLs, monitoring crawl activity, and managing indexing, and registering an account often requires a mainland Chinese phone number. Baidu still gives weight to signals that Google has largely moved away from, such as meta keywords and exact-match, keyword-aligned title tags. Page speed on mobile matters a great deal. Baidu also tends to surface its own properties and content from Chinese platforms such as Baidu Tieba and Zhihu, so visibility strategies often extend beyond your own website.

Finally, content on Baidu must comply with Chinese government regulations on what can be published. This is a meaningful difference from Google and requires care to avoid material that would be filtered or removed.

What to ask an SEO company

Treat Baidu as a specialist request. When you talk to an agency, ask whether they have done Baidu projects before and what those projects involved. Ask how they would handle the ICP filing, whether they have a local partner in China, and how they would manage in-China or nearby hosting. Ask who would write and review the simplified Chinese content, since a native-level writer or editor is important here. Ask how they work with Baidu’s own webmaster tools and how they keep content within Chinese compliance rules.

A general SEO company may take on this work in one of three ways. Some have built genuine in-house China-market capability. Some partner with a specialist agency or local team and coordinate the project for you. Others do not offer it at all and will tell you so. Any of the first two can work, but only if the people doing the actual Baidu work have real experience with the market.

The practical takeaway

Baidu optimization is achievable and worth considering if mainland China is a target market for your business. It is not, however, a routine add-on to a standard SEO engagement. Confirm that the company either has direct Baidu experience or a clear, named arrangement with China-market specialists. If an agency promises Baidu results but cannot explain ICP filing, China hosting, or simplified Chinese content, treat that as a sign they are not equipped for the work.

The short answer is no, not in the way many business owners hope. An SEO company cannot simply delete a genuine negative review you received from a real customer. No agency has a back-door button for that, and any company that promises to make real reviews disappear is making a claim it cannot keep. Reviews on platforms like Google and Yelp belong to the platform and the person who wrote them, not to your business or your agency.

What a legitimate SEO or reputation company can do is work within the rules each platform sets. That is a meaningful difference, and it is worth understanding before you hire anyone to help.

What a company can legitimately do

The first legitimate option is flagging reviews that break platform rules. Google and Yelp both remove reviews that violate their content policies, but they do not remove a review just because it is negative, harsh, or old. A review qualifies for removal only when it breaks specific rules. On Google, that includes reviews not based on a real experience, paid or incentivized reviews, reviews posted from multiple accounts by one person, reviews left by a competitor to damage your business, and spam or off-topic content. Yelp applies similar standards and also removes reviews that contain hate speech, threats, or harassment.

When a review appears to break these rules, a company can flag it through the platform’s reporting tools and select the violation category. The platform then decides. It may remove the review, leave it in place, or escalate the case. Typical review times run a few business days, and there is no guarantee of removal. The agency’s role here is to identify genuine violations and submit a clear report, not to control the outcome.

The second legitimate option is responding to reviews professionally. A calm, specific, public reply to a negative review shows future customers that you take feedback seriously. This does not remove the review, but it changes how readers interpret it.

The third option is encouraging more genuine reviews from satisfied customers. A single one-star review carries far less weight when it sits among many honest, positive ones. Note that platforms have tightened the rules here. Google now prohibits practices such as review gating, where you only ask happy customers for reviews, along with review kiosks at reception and staff review quotas. A trustworthy company will ask every customer fairly and will never buy or incentivize reviews, since fake or paid reviews are exactly what platforms remove.

The fourth and most important option is addressing the root issues. If several reviews mention the same problem, the lasting fix is to correct that problem in your business. Reputation work that ignores the underlying cause only delays the next negative review.

Watch for these red flags

Be cautious of any company that guarantees it can erase real negative reviews, claims a special relationship with Google or Yelp that lets it delete content, or offers to pay the platform for removal. Yelp does not allow businesses or partners to pay for review removal, and Google does not either. Some operators use manipulative tactics such as mass-flagging legitimate reviews with false violation reports. This can backfire. Platforms can restrict a business profile for repeated abuse, which may limit your ability to respond to reviews or place a consumer alert on your listing.

You should also avoid any company that pressures or pays the original reviewer to take a review down. Both platforms forbid this, and it can damage trust if it becomes public.

The honest takeaway

An SEO or reputation company cannot delete genuine negative reviews, and it should never claim otherwise. What it can do is flag rule-breaking reviews for the platform to judge, help you respond well, support a steady flow of honest reviews, and guide you in fixing the problems behind the complaints. Hire a company that explains these limits clearly. The ones that promise to erase your reviews are the ones to walk away from.
