To choose an SEO company in Kolkata, start with what Google itself tells business owners: no one can guarantee a #1 ranking, a good SEO explains every change they make, and you should be wary of anyone who claims a special relationship with Google or talks about link schemes. Then ask practical questions about reporting, access, contracts and who owns the work. This guide gives you both: Google's red flags and a checklist you can use in your next agency meeting.
This post is only about hiring for search engine optimisation. If you're comparing agencies that also run ads, social media and websites, read our guide on how to choose a digital marketing agency in Kolkata.
What an SEO company should actually do for you
Google's Search Central page "Do you need an SEO?" lists the kind of work a legitimate SEO provides:
- a review of your site's content and structure;
- technical advice on development, such as hosting, redirects, error pages and use of JavaScript;
- content development;
- keyword research;
- SEO training for your team.
The same page says a great time to hire is when you're planning a site redesign, and the earlier the better. That matters for many Kolkata businesses that rebuild their website every few years: bringing SEO in after launch often means fixing redirects and lost pages that could have been planned for.
Notice what isn't on that list: buying links, submitting your site to "thousands of search engines" or any secret method. If a proposal is built around those, treat it as a warning.
Google's red flags, in plain English
Google is unusually direct about this. Here are the warnings from its official guidance and what they look like in real sales pitches.
| What Google says | What you might hear |
|---|---|
| "No one can guarantee a #1 ranking on Google." | "Page one in 30 days or your money back." |
| Beware of SEOs that allege a "special relationship" with Google or advertise a "priority submit". | "We're a Google partner, so we can get your site indexed faster." |
| Avoid SEOs that talk about link popularity schemes or submitting your site to thousands of search engines. | "We'll build 500 backlinks a month." |
| "You should never have to link to an SEO." | A contract that requires a "designed by" or "SEO by" link in your footer. |
| Be careful if a company is secretive or won't clearly explain what they intend to do. | "Our method is proprietary, just trust the process." |
| Be wary of SEO firms that email you out of the blue. | A cold email saying your site "has 47 critical errors" with a ready-made package price. |
One clarification on the second row: Google also states that advertising with Google won't affect your site's presence in organic results, and that Google never accepts money to include or rank sites there. An agency's Google Ads credentials say something about its ads work. They don't give it any pull in organic search.
Google also reminds site owners that "ultimately, you are responsible for the actions of any companies you hire." Its spam policies list the tactics that can push a site down or out of results, and buying or selling links for ranking purposes is one of them. If an agency's shortcuts get your site demoted, it's your site that suffers.
Questions to ask before you sign
Google suggests a set of questions to ask any SEO. We've grouped them with the practical ones that tend to cause disputes later.
About their approach
- Can you show examples of previous work? Google suggests asking for examples and success stories, and talking to past clients about whether the service was useful. Ask for references you can call, not just logos on a slide.
- Do you follow Google Search Essentials? The answer should be a clear yes, with an explanation of what that means for your site.
- What results do you expect, in what timeframe, and how will you measure success? A good answer is specific about measures (enquiries from organic search, visibility for service pages, calls from your Business Profile) and honest about uncertainty.
- What do you need to know about my business? Google notes that a good SEO asks what makes your business unique and who your competitors are. If they quote before asking anything, they're selling a package, not a plan.
About transparency and reporting
- Will you tell me every change you make to my site? Google lists this as a question to ask. Get the answer in writing.
- What will the monthly report contain? Ask to see a sample. Useful reports explain what was done, what changed in Search Console and analytics, and what's planned next. A list of keyword positions alone tells you very little.
- Who will actually work on my account? In a small agency it may be the founder. In a large one it may be a junior executive. Both can work, but you should know.
About access and ownership
- Search Console and analytics stay in your name. Create the accounts yourself and add the agency as a user. For an initial audit, Google's advice is to grant only read access to Search Console, not write access.
- Who owns the content? Blog posts, service pages and images written for your site should belong to you, in writing, including after the contract ends.
- Who controls the domain, hosting and Google Business Profile? These should be registered to your business. Agencies can be managers, not owners.
- What happens if we stop? Ask about notice periods, handover of logins and whether any work (links, pages, tracking) gets removed when you leave.
About the contract
- Is the scope written down? "Monthly SEO" is not a scope. A deliverables list (pages per month, technical fixes, Business Profile updates, reporting) is.
- Is there a lock-in? SEO usually takes months, so a minimum term can be reasonable. A long lock-in with no exit for poor service is not.
- Are third-party costs separate? Tools, content writers, photography or development time may be billed on top. Ask now, not on the first invoice.

What a good first audit looks like
Most agencies start with an audit. Google says an audit should give you "realistic estimates of improvement, and an estimate of the work involved." In practice a useful audit:
- is about your site, with your actual URLs and Search Console data, not a generic tool export;
- separates serious problems (pages that can't be indexed, broken redirects after a redesign) from cosmetic ones;
- puts fixes in priority order with rough effort for each;
- explains things in language you can follow.
Be careful with audits built entirely from third-party tool scores. Google states that it doesn't evaluate or endorse third-party SEO tools, that those tools don't have access to its internal ranking data, and that you should be wary of tools claiming to be "approved" by Google Search. Tools are useful for spotting issues. A score from one isn't a Google verdict.
Local factors for Kolkata businesses
A few points come up often when a Kolkata business is choosing an SEO partner. These are practical suggestions, not rules:
- Ask about local search specifically. If your customers find you on Google Maps, your Business Profile matters as much as your website. Google's help page says there's no way to pay for a better local ranking, so the agency's job is accurate information and genuine prominence. Our local SEO guide covers the basics.
- Ask about Bengali content if your customers search in Bengali. Many Kolkata customers search in English, some in Bengali and some in a mix. The agency should ask which applies to your customers rather than assume.
- Meet the people. Being in the same city makes it easier to visit your shop or clinic, take real photos and understand which neighbourhoods you actually serve.
- Check regulated industries. Clinics and doctors have advertising restrictions. If that's you, ask how the agency handles them and read our NMC 2026 checklist.
A quick scoring checklist
Use this after each meeting. Any "no" deserves a follow-up question.
- They didn't promise a specific ranking or position.
- They explained what they'll do, in terms you understood.
- They asked about your business, customers and competitors.
- They'll share every change made to your site.
- You keep ownership of Search Console, analytics, domain, hosting and Business Profile.
- Content they create belongs to you.
- No link packages, no required footer link, no "thousands of directories".
- You've seen a sample report and spoken to a past client.
- The contract has a written scope and a fair exit.
