Career history

Where Gaurav Singh Mehra has worked

Gaurav Singh Mehra has spent over 10 years in organic marketing and SEO roles across five industries, rising from sales executive to Growth Manager and Digital Marketing Team Lead, alongside five years of parallel freelance consulting covering 200+ client engagements.

Most SEO people come from one environment. I've worked in a software company, a marketing agency, an e‑commerce group, a bank and a media business, which means I've had to make organic growth work under completely different constraints: engineering‑led roadmaps, client billability, thin retail margins, compliance sign‑off, and campaign‑cycle thinking. That range is the reason I can walk into a new setup and know within a week where the real bottleneck sits.

Digital Marketing Team Lead · Apptunix

AI‑powered software development & digital transformation

Led the digital marketing function for a technical B2B product and services business, owning organic growth end to end and directing the team delivering it. Worked directly with engineering and product on site architecture, technical SEO and release‑cycle requirements, and built the channel for long, multi‑stakeholder enterprise buying cycles where the reader is technical and the decision is never impulsive. Also where my AEO and GEO work started, because AI‑native buyers were the first group to move their research into AI assistants.

3 years

Team Lead · Deftsoft

Digital marketing agency

Led a team running SEO and organic strategy across a portfolio of client accounts simultaneously, spanning industries and markets. Agency work is where you learn to diagnose fast, prioritise ruthlessly under a billable hour, and present to clients who need the commercial case rather than the audit. It is also where I moved from doing the work myself to being accountable for other people's output: briefing, reviewing, and answering to the client when it slipped.

2 years

Growth Manager · Group of e‑commerce companies

Multi‑brand online retail

Owned growth across multiple retail brands in one group, with organic as the primary channel and paid, email and CRO run alongside it. Category and product taxonomy at scale, faceted navigation and index control, feed and content quality, seasonal demand planning, and conversion work on revenue‑critical templates. Retail is unforgiving: margin is thin and every ranking change shows up in revenue within days, which is the fastest feedback loop I have worked in.

1 year

Sales Executive · ICICI Bank

Retail banking

Front‑line sales in a regulated financial environment, before I moved into marketing. Two things from it still shape how I work. First, I have heard the actual objections customers raise at the point of decision, which is why I write for intent rather than for keywords. Second, financial services is where nothing goes out without compliance sign‑off, so approval chains and YMYL‑grade scrutiny are constraints I learned to work inside rather than complain about.

2 years

Digital Marketing Executive

Media & advertising

My first marketing role, on the publishing and advertising side: content at high volume, editorial SEO, audience growth, and the commercial relationship between traffic and ad revenue. Publishing runs at a speed most brands never experience, and learning content operations there is why large content programmes do not intimidate me now.

5 years, parallel

Independent consulting

200+ engagements · 15+ markets

Alongside those roles I've consulted independently for clients across SaaS, e‑commerce, real estate, healthcare, finance, legal and professional services, in the US, UK, Gulf, Europe and Asia‑Pacific. A selection is documented in the work section below.

Scope & accountability

The scope Gaurav Singh Mehra takes accountability for

Whether it's a role or a mandate, this is what sits with me. Not tasks I can perform, outcomes I answer for.

Channel strategy & ownership

I own the organic roadmap end to end: where the opportunity is, what gets built in what order, what we deliberately don't do, and what the channel is forecast to return. Leadership gets one accountable owner instead of a set of suppliers to coordinate.

The commercial number

Sessions are an input, not a result. We define the metric the channel is judged on at the start, whether that's qualified pipeline, signups, bookings or revenue, and I report against that number every cycle whether it's good news or not.

Cross‑functional execution

Most SEO fails at the handoff, not the strategy. I write specs engineers accept, briefs writers can use, and tickets that survive sprint planning. I work inside your backlog rather than emailing PDFs at it.

Team & vendor direction

If you have in‑house marketers, I direct and upskill them. If you have agencies or freelancers, I manage them, set scope, and hold them to it. Either way you stop being the person coordinating SEO.

Stakeholder communication

I present organic performance to founders, boards and non‑marketing leadership in language they can act on. No dashboard handed over without interpretation, and no metric on a slide that nobody can make a decision from.

Risk management

Migrations, replatforms, algorithm updates, penalties, negative SEO. The downside cases are where a senior hire earns the cost, and I've handled all of them in live revenue environments.

Revenue & outcomes

The numbers Gaurav Singh Mehra has been accountable for

Organic is only worth what it returns. These are the outcome measures I have owned as a Digital Marketing Team Lead, Team Lead and Growth Manager, rather than the activity metrics that are easy to make look good.

$25M+

Revenue influenced

Attributable revenue driven through organic and integrated growth work across in‑house roles and client engagements. The number I lead with, because it is the one leadership actually asks about.

40%

Of inbound pipeline from organic

Share of qualified inbound that organic contributed at its peak in a B2B setting. Getting organic from a cost line to a named share of pipeline is what moves the channel into board conversations.

12

People led

Marketers, writers, designers and developers directed across SEO, content and paid, plus external agencies and freelancers held to scope. Output through other people, not just my own hours.

60%

Lower CAC than paid

Cost of acquisition through organic versus paid on comparable buying intent. The comparison that decides where the next marketing pound or dollar goes.

3 of 3

AI engines citing the brand

A client surfaced as a recommended option in ChatGPT, Gemini and Perplexity for target prompts. AI visibility tracked as its own channel with its own reporting, not as a side note.

200+

Engagements across 15+ markets

Delivered across SaaS, e‑commerce, real estate, healthcare, finance, legal and professional services in the US, UK, Gulf, Europe and Asia‑Pacific. Breadth is why new constraints are rarely new.

Happy to walk through the data behind any of these, with account access, on a call.
Expertise

What Gaurav Singh Mehra works across

Gaurav Singh Mehra works across the full organic and growth stack, from technical SEO and AI search visibility to paid media, reputation and brand. Search is one part of a discovery and conversion system now, so these domains get run as one strategy rather than twelve separate services.

Technical SEO & Site Architecture

The foundation everything else depends on. Crawl budget, index control, architecture and speed, diagnosed at log‑file level rather than from a tool score.

  • Crawl & index control
  • Site architecture & internal linking
  • Core Web Vitals remediation
  • Migrations & replatform recovery

AEO & GEO: AI Search Visibility

Buyers now shortlist inside ChatGPT, Gemini and Perplexity before they ever see a blue link. Either your brand is in that answer or it doesn't exist.

  • Entity & knowledge graph clarity
  • Structured data & schema strategy
  • Citation‑ready content structure
  • AI share‑of‑voice tracking

Content Strategy & Editorial Ops

Volume without a system produces expensive noise. Topical authority built deliberately, with the editorial process that holds quality as output scales.

  • Topical authority mapping
  • Intent‑led briefs & guidelines
  • Refresh & consolidation programmes
  • Editorial QA at scale

Digital PR & Authority Building

Links earned by work that deserves coverage, not bought from a vendor list. Plus the unglamorous defensive side most people skip entirely.

  • Data studies & expert commentary
  • Journalist & publisher outreach
  • Toxic backlink audits
  • Penalty recovery & disavow

Paid Media & Channel Integration

Paid and organic run as one funnel, not two silos with separate reports. Paid tests intent in days, organic compounds whatever proves out.

  • Paid search & shopping
  • Paid social & retargeting
  • Organic‑paid keyword arbitrage
  • Blended CAC & budget allocation

Conversion Rate Optimisation

Traffic that doesn't convert is a cost centre with good‑looking charts. Find where intent leaks out of the funnel, then fix it with evidence.

  • Landing page architecture
  • Funnel & drop‑off diagnosis
  • Hypothesis‑driven A/B testing
  • Form & checkout friction

Reputation & Review Management

Search results are the first impression, and page one for your brand name is the highest‑intent moment you have. It shouldn't be left to chance.

  • Review generation systems
  • Sentiment monitoring & alerts
  • Negative result suppression
  • Crisis response playbooks

Brand, Positioning & Narrative

Branded search volume is the most durable asset in organic and the only one competitors can't copy. It gets built on purpose, not by accident.

  • Category positioning
  • Messaging architecture
  • Branded demand generation
  • Thought leadership programmes

Local & Multi‑Location Visibility

For service and retail businesses the Map Pack is the market. Won location by location, not with one national strategy applied everywhere.

  • Google Business Profile optimisation
  • Location page architecture
  • Citation & NAP hygiene
  • Proximity & Map Pack tracking

Analytics, Attribution & Forecasting

Most organic reporting answers questions nobody asked. Measurement configured so decisions actually get made from it.

  • GA4 & Search Console configuration
  • Server‑side & event tracking
  • Opportunity forecasting & modelling
  • Executive reporting frameworks

Web Performance & Dev Oversight

SEO built into the architecture instead of retrofitted after launch, which is where most of the cost quietly hides.

  • SEO‑first site architecture
  • Developer‑ready technical specs
  • Schema implementation
  • WordPress, Shopify, Webflow, headless

Team Building & Enablement

The measure of a good engagement is whether the channel keeps running after I stop. That takes process and trained people, not documents.

  • SEO hiring & interview frameworks
  • Onboarding & training programmes
  • Documented workflow & QA gates
  • Agency & vendor management

Not sure which of these you actually need?

Tell me the gap you're trying to fill and I'll tell you which of these matters for your situation, which doesn't, and what I'd do in the first thirty days. If it isn't me you need, I'll say that too.

Onboarding plan

What the first 90 days looks like

No discovery phase that eats a month. This is the sequence, and it barely changes whether I'm in a role or on a mandate.

Days 1–30

Diagnose and prove

Full technical, content and authority audit. Analytics and Search Console validated first, so we're not building on numbers that are wrong. Competitor and AI‑visibility baseline set. Quick wins shipped inside the first fortnight, because momentum matters and because it proves I can move work through your process. You get a prioritised roadmap with forecast impact, not a 90‑page document nobody opens.

Days 31–60

Build the engine

Technical remediation in flight with engineering. Content briefing process live and producing. Entity and structured data foundation in place for AI search. Measurement framework agreed with leadership so everyone is judging the channel by the same number. Team and vendor scope clarified and documented.

Days 61–90

Compound and scale

Content and authority programmes running at cadence. First full reporting cycle against the commercial metric. Roadmap re‑forecast on real data instead of opening assumptions. What works gets more resource, what doesn't gets cut without ceremony.

How I work

A clear operating process, not a black box

Once the channel is running, this is the loop it runs on. You always know what's happening, why, and what it's moving.

Diagnose

Technical, content and authority reviewed on a cycle. I map where you rank, where traffic leaks, and the fastest path to commercial impact.

Prioritise

Opportunities clustered by intent and sized by forecast return, so the roadmap is ordered by commercial impact rather than audit severity.

Spec

Work written as tickets engineers accept and briefs writers can use, sized to fit your sprint and your approval chain.

Ship

Technical, content, authority and AI‑search work implemented, directly or through your team and vendors, with clean handoffs at every step.

Report & re‑forecast

Reporting against the agreed commercial metric, weekly or monthly. The forecast gets corrected on real data, then resource follows what works.

Accountability

How to judge whether I'm working

Rankings are a leading indicator, not a result. Set the target with me on day one and hold me to it.

The problem

Invisible in the Map Pack across most service areas, while paying for search ads in the same postcodes. Local demand existed and was being handed to competitors.

The problem

Negative results ranking on page one for brand queries, costing conversions at the highest‑intent moment in the funnel: the point where a buyer checks who they're dealing with.

The problem

Buyers were shortlisting vendors inside ChatGPT and Perplexity before reaching Google, and the brand appeared in none of those answers. Ranking well was no longer enough to be considered.

Why work with me

Why You Should Hire Gaurav Singh Mehra

10+ years across in‑house, agency and independent work, now focused entirely on owning organic growth as a commercial channel.

One accountable owner

You're not briefing a team and hoping it lands. One senior person owns strategy and execution and answers for the result.

Commercial before technical

Perfect technical SEO is worthless if nobody can tie it to revenue. Every roadmap is sequenced by commercial impact, not audit severity score.

Five industries, not one

Software, e‑commerce, banking, media and agency. Engineering constraints, thin margins, compliance review and billability are situations I've worked in, not read about.

Built for how discovery works now

Google is one surface. AI answer engines are treated as a measured channel with their own reporting, not a trend slide at the end of a deck.

Work that actually ships

Specs engineers accept and briefs writers can use. Recommendations dying unshipped in a document is the most common way SEO fails.

Leaves capability behind

Documented process, trained people, systems that keep running. If you eventually don't need me, that was a good engagement, not a lost account.

What the people Gaurav Singh Mehra has worked with say

We were a local business that couldn't be found online, and we had been through two agencies before Gaurav. The difference was that he treated it as a business problem rather than a checklist. He restructured how our locations were set up, fixed our Google Business Profiles properly, and put in a review process our own team could keep running. Within a few months we had a steady flow of qualified enquiries from our service area, and we understood why, because he explained every decision in terms we could actually follow.
William
WilliamGrowth Marketing Manager
Gaurav came in when our organic channel had gone flat and nobody internally could work out why. What stood out was that he arrived without a template. He spent the first weeks understanding our marketplace dynamics and our margins before proposing anything, and the strategy he built was specific to how our buyers actually search. He is the rare consultant who is comfortable in a leadership conversation and a technical one on the same day.
Amanda T
Amanda TCEO, Marketplace VVC
Hiring Gaurav changed how we think about organic growth. He took full ownership of the channel, worked with our developers directly instead of routing everything through me, and reported in a format our board could act on. He was also straight with us about what would not work, which I valued more than the wins. By the end our team had the process and documentation to carry on independently.
Mark S
Mark SCEO, WIK Networks
One of the best decisions we made. Gaurav's technical depth is genuinely senior, but what set him apart was prioritisation. He was ruthless about sequencing work by commercial impact instead of handing us a 200‑item audit and walking away. We hit top positions for our target commercial keywords and, unusually, I could explain to my CEO exactly why. He operated as part of our team, not as a supplier.

FAQ

Questions before we talk

Three things that are checkable rather than claimed. First, range: 10+ years across an AI software company, a digital marketing agency, an e‑commerce group, a bank and a media business, which means organic growth under engineering constraints, thin retail margins, compliance review and agency billability are situations I have already worked in rather than read about. Second, ownership: I run organic as a channel with a commercial number attached, and I direct engineers, writers, agencies and in‑house teams to get work shipped, rather than producing recommendations and leaving. Third, current relevance: I work on AI search visibility across ChatGPT, Gemini and Perplexity as a measured channel, which is where a growing share of high‑intent research now happens. Ask me for the data behind any of it and you'll get it.
Message me and we'll cover your situation, the gap you're filling, and which model fits. For fractional and mandate work I can typically start within one to two weeks. For a full‑time role I follow your standard hiring process and am available for interviews immediately.
It depends on whether you're missing strategy, execution, or both. If organic is core to your business and there's enough volume for a permanent role, hire full‑time; a good senior hire beats any external arrangement. If you need broad fulfilment capacity across many channels, an agency makes sense. If you have people who can ship but nobody senior setting direction, an embedded lead is the efficient answer. I'll tell you honestly which one your situation calls for, including when it isn't me.
It depends on the model and scope. Advisory is hourly, fractional is a day rate or monthly retainer, mandates are fixed scope. For context, senior independent consultants generally price above agency hourly rates and well below the true annual cost of a comparable full‑time hire once salary, benefits, tooling and overhead are counted. Ask me directly and you get a number, not a discovery call.
Yes. A migration, an audit, a penalty recovery or an AI‑visibility build‑out all work as defined mandates with fixed scope and an end date. I'll tell you if the problem you've described actually needs ongoing ownership instead of a project, because that's a common reason projects don't stick.
Yes. Enterprise work is less about site size and more about coordination: multiple stakeholders, engineering constraints, legal and brand approval chains, multi‑market and multi‑language setups, and migration risk on revenue‑critical properties. My time in banking and inside an enterprise software business is directly relevant to all of it.
Answer Engine Optimisation and Generative Engine Optimisation are about appearing inside AI‑generated answers rather than in a list of links. When a buyer asks ChatGPT or Perplexity to recommend options in your category, your brand is either in that answer or it isn't, and there's no second page to be on. The work is entity clarity, structured data, content built to be cited, and presence across the sources these systems draw from. I run it as a measured channel with its own reporting, not as an add‑on.
Technical and foundational fixes can move things within weeks. Content and authority programmes compound over three to six months, and competitive markets take longer. In the first month you get a validated diagnosis, a forecast and shipped quick wins, so you can judge direction well before the full curve arrives.
No, and anyone who does is either misinformed or lying, because nobody controls a search algorithm. What I commit to is a transparent process, a forecast I'll defend, reporting against an agreed commercial metric, and telling you early when something isn't working.
Yes, and it's often the highest‑leverage part of the engagement. I direct in‑house marketers, manage external agencies and freelancers, set their scope, review output, and run hiring and interviewing when you're building the team out.
Yes. Gaurav Singh Mehra is open to senior and leadership organic marketing and SEO roles, and is available for interviews now. Message me and we can go through the role, the scope and my background in detail.
