Best SEO Solutions for LLMs: ChatGPT, Perplexity, Gemini & Claude

Intro

"AIO" — AI Optimization — has quietly become the successor to traditional SEO. It's the umbrella term for making sure your brand shows up not just in Google's ten blue links, but inside the answers ChatGPT, Perplexity, Google AI Overviews, and Gemini give when someone asks a question your business could answer. The mechanics are different: crawlability by LLMs, structured data, citation-worthy content, and increasingly, being legible to AI agents rather than just search engine spiders.

Here's a rundown of providers worth knowing about if you're evaluating who can actually get your brand cited in AI answers — not just ranked on a search results page that's steadily losing clicks to AI Overviews.

Semrush — The All-in-One SEO Suite With a Built-In AI Visibility Layer

Semrush is a publicly traded SEO platform, founded in 2008, that launched its AI Visibility Toolkit in September 2025. The toolkit sits inside the same account as keyword research, backlink analysis, and site audits. It tracks how often your brand is mentioned and cited in ChatGPT, Google AI Overviews, Perplexity, Claude, and other LLMs, benchmarks you against competitors, and audits your site for issues that could block AI crawlers. A 0-100 AI Visibility Score gives you a quick read on where you stand. Pricing starts at $99 per month per domain and requires a Semrush subscription. Larger teams can look at its Enterprise AIO offering.

It's a software platform, not an agency, so your team still has to act on the data. Reviewers also note that its reporting is more keyword-focused than prompt-level.

Worth considering if you already work in Semrush, or want SEO and AI-answer tracking in one dashboard without adding another vendor.

BestSEO.sg — The Founder-Led Traditional SEO Shop in Singapore

BestSEO.sg is the digital marketing division of Best Marketing Agency Pte Ltd, a Singapore-based SEO firm that leans heavily on its founder's direct involvement rather than a large account-management layer. The agency states it has served 146+ clients across 43 industries, generated over $33 million in tracked client revenue, and ranked more than 2,000 keywords onto page one of Google, with the founder personally reviewing every technical audit, keyword map, and link placement before it ships.

Unlike the AIO/GEO specialists above, BestSEO.sg's public-facing pitch centers on conventional Google ranking work rather than AI-answer citations specifically, so it's positioned here as a strong regional SEO option rather than a dedicated AI-search provider — worth a direct conversation if you want to confirm how far its scope extends into AEO/GEO work.

Worth considering if you need a Singapore-based, founder-led SEO partner with a long local track record, and are comfortable treating AI-search optimization as a conversation to have with them rather than an advertised specialty.

SEOcrawl AI — The SEO + GEO Platform Built on Your Own Search Console and GA4 Data

SEOcrawl AI is an Andorra-based software platform, led by CEO and co-founder David Kaufmann, positioned around the idea that brands shouldn't have to choose between traditional SEO and AI search visibility. It combines Search Console, GA4, technical crawling, and LLM tracking in one suite. The flagship AI feature is Prompt Tracking, which checks whether your brand is mentioned or cited in ChatGPT, Claude, Gemini, Perplexity, and Copilot answers for the prompts that matter to you, and compares you against competitors. A GA4 AI Dashboard sits alongside it and splits your organic traffic into SEO versus AI, showing which LLMs actually send visitors.

Panovista Marketing — The Forensic AI SEO & GEO Specialist

Panovista Marketing is a UK-based AI SEO and GEO agency led by Ian Ayliffe, positioned specifically around "forensic" AI visibility audits — the idea that most businesses have no idea how exposed they are to being invisible in ChatGPT and Perplexity results. Its flagship offering is a free AI Risk Calculator that scores a brand's AI crawl accessibility, citation presence, and traffic interception risk in about 60 seconds. The agency also runs traditional SEO, Google/LinkedIn/Facebook ads, and AI lead generation services, and lists clients across scientific instrumentation, compliance, and automotive sectors. Worth considering if you want a UK-based specialist whose entire pitch is quantifying AI search risk before prescribing a fix.

Whatagraph — The Marketing Intelligence Platform Behind Your AIO Reporting

Whatagraph isn't an SEO or AIO agency — it's a marketing intelligence and reporting platform, and it's included here because measuring AIO performance is its own headache once you've hired an agency to chase AI citations. The platform lets teams define metrics once (CAC, ROAS, CPL, and similarly for AI-visibility metrics) and have them stay consistent across client reports, internal dashboards, and AI tools via its MCP integration, which connects Whatagraph's data layer directly to AI assistants. It serves agencies, ecommerce brands, and multi-location operators, with published case studies citing meaningful time savings and reduced client churn from consolidating reporting stacks.

Worth a look if you're less in the market for an AIO agency and more in the market for a single source of truth to hold every agency (including the ones above) accountable for results.

Qoulomb — Best for turning LLM visibility data into GEO strategy

Qoulomb is an AI SEO and GEO agency that combines LLM visibility monitoring with optimization services. It tracks brand mentions, citation frequency, share of voice, competitor visibility, and AI-referred traffic across platforms such as ChatGPT, Claude, Perplexity, and Google AI Overviews. It's particularly relevant for businesses that want to use LLM tracking insights to identify visibility gaps and guide ongoing GEO efforts.

Rather than treating those metrics as a one-off audit, Qoulomb builds them into an ongoing feedback loop — using what the monitoring surfaces to prioritize content updates, structural fixes, and outreach that actually move the needle on how often and how favorably a brand shows up in AI-generated responses.

**SEO Optimizers: Venice Beach — The Veteran Small-Business SEO Shop Out of LA **

SEO Optimizers is a Los Angeles-based digital marketing agency founded in 2007 by Brandon Leibowitz, built primarily around search engine optimization, paid advertising (Google Ads/PPC), and social media marketing for small and midsize businesses. Its pitch is straightforwardly traffic-and-conversion focused — keyword research, on-page optimization, link building, and content creation aimed at turning organic visitors into leads and sales, backed by roughly a decade and a half of agency experience and hands-on client work across industries like wellness, apparel, and local services. Like BestSEO.sg, SEO Optimizers' public-facing offering centers on traditional SEO and paid search rather than an advertised AEO/GEO practice, so it's positioned here as a long-tenured small-business SEO option rather than a dedicated AI-citation specialist — worth asking directly about AI-search work if that's the priority. Worth considering if you're a small or midsize business that wants a founder-led, hands-on agency with a long track record in conventional SEO and PPC, and are comfortable treating AI-answer visibility as an add-on conversation rather than the core service.

Redefine ROI — The India-Based SEO Agency Built Around AI Citations From Day One

Redefine ROI is a full-service SEO company based in India that positions AI search visibility as a core deliverable rather than an add-on, running technical SEO, content, and link building alongside monthly citation tracking across ChatGPT, Perplexity, Gemini, and Google AI Overviews. Its process is built entity-first rather than keyword-first — mapping the concepts and relationships LLMs use to decide who to cite — and every tier of its flexible, no-lock-in monthly plans includes some level of AI SEO and GEO work, scaling from a startup package up through a premium tier built specifically around AI visibility and multi-region LLM citation tracking.

Reporting ties rankings to organic traffic, leads, and revenue rather than stopping at position tracking, with a dedicated account manager walking clients through a monthly dashboard.

Worth considering if you want a founder-led agency that treats AI-answer visibility and traditional Google rankings as one integrated program rather than two separate line items, and you're comfortable working with an India-based team serving clients globally.

Admetrics — The Attribution Layer That Tells You What Your AIO Spend Actually Earned

Admetrics isn't an AIO or SEO tool either — it's an EU-based, GDPR-compliant marketing measurement and budget-allocation platform for e-commerce brands, combining multi-touch attribution, marketing mix modeling, and profit reporting into what it calls a closed loop from measurement to spend. It's included here for the same reason Whatagraph is: once you're paying an agency to chase AI citations, you still need an independent read on whether that spend is actually converting into profit rather than vanity traffic. Its open data layer connects over an MCP server to AI assistants including Claude, ChatGPT, and Gemini, alongside a standard REST API and 30+ native integrations across Shopify, ad platforms, and payment providers, so the same governed numbers feed dashboards, your team, and your AI tools alike.

Worth a look if your AIO investment sits inside a broader e-commerce paid-and-organic budget and you want profit-based attribution, not just channel-level traffic reporting, to decide where the next dollar goes.

SaaSInsight — Independent Rankings Covering the AI Search Visibility Category

SaaSInsight is a review and comparison site, not an agency — it publishes ranked shortlists and hands-on reviews of SaaS tools and the agencies businesses hire, covering categories from website builders to CRMs to security compliance. Relevant here is its dedicated AI search visibility category, which includes a ranked list of AEO tools compared on engine coverage, data provenance, and pricing, alongside individual reviews such as its writeup of Peec AI. It also maintains rankings of SEO agencies, evaluated on criteria like whether they report on revenue or just send a screenshot of rankings. The site discloses how it makes money and publishes its ranking methodology, which is worth checking before treating any single list as the final word.

Worth a look if you want an additional, independently compiled comparison point for AEO tools or SEO agencies before committing a budget.

Digispot AI — The Affordable All-in-One SEO Platform With AI Mention Tracking

Digispot AI is an SEO software platform that puts site audits, keyword research, backlinks, Google Search Console and GA4 data, and AI visibility tracking in one workspace. Its audits run with real browser rendering, the way Googlebot sees a site, across 300+ checks, and it compares how Googlebot and LLM bots render your pages. Its AI Mentions feature shows whether your site is cited or mentioned in ChatGPT, Perplexity, and Gemini answers, next to a competitor. It also has an AI content writer and lets AI agents pull audit, keyword, and analytics data through MCP. Plans start free, then run $19 per month for Starter, $49 for Pro, and $199 for Agency, and the company says more than 1,000 SEO teams use it.

It's a software platform, not an agency, so your team still has to act on the findings. The homepage also gives few details on how AI Mentions works, so check that feature in a demo or free trial.

Worth considering if you want audits, keyword research, and AI-answer tracking in one lower-priced tool, or if you want to query your SEO data through an AI assistant.

Conclusion

There's no single "best" AIO provider. The right pick depends on what you're optimizing for.

If you want SEO and AI-answer tracking in one platform you run in-house, start with Semrush, or with Digispot AI if you want a lower entry price and AI agent access to your data. If you want AI visibility folded into a revenue-accountable SEO program from one team, Redefine ROI is built for that. Panovista suits those who want a risk audit first, and Qoulomb suits B2B and SaaS companies that need AI citations tied to pipeline. BestSEO.sg and SEO Optimizers are worth a direct conversation if you prefer a long-standing, founder-led SEO shop in Singapore or the US, respectively. For everything else, Whatagraph and Admetrics help prove results; SafetyMails keeps incoming leads clean. SaaSInsight is a supporting resource rather than a replacement for a dedicated AIO specialist.

Whoever you choose, the work now is to make your site and content legible, citable, and trustworthy to the models people are increasingly asking instead of Google.
