### SE Ranking

Your Search Ecosystem, Finally in One Place Search has fundamentally changed. The rankings, AI-generated answers, local visibility, brand mentions, and social signals that shape your digital performance no longer operate in isolation — and your data should not either. SE Ranking gives you a connected view of your search ecosystem so you can understand what is actually driving results, adapt as the landscape shifts, and walk into stakeholder conversations with clarity rather than approximations. Ecosystem-Level Insights Across Every Channel That Matters Your core SEO workflow is here: keyword research, technical site audits, backlink analysis, competitive intelligence, local SEO, and content marketing tools — accurate and built for teams that depend on them to make decisions, not just to report metrics. But where SE Ranking goes further is in connecting those SEO foundations to the wider channels now shaping your brand visibility. Your GA4 data flows in without friction, adding traffic context and user behavior data to how you read search and AI visibility signals — so you are not interpreting ranking movements in isolation from what is actually happening to your audience. SE Visible, an extension of SE Ranking, lets you look at that same data from a different perspective by adding brand and AI search visibility as an additional layer. Planable completes the picture on the content side with a collaborative social media management environment where teams plan, schedule, approve & publish across channels with multi approval workflows, and content calendar tools built for the way teams actually work. Together, these layers of data allow you to draw the kind of cross-channel correlations your leadership and clients are starting to ask for by name — and to see them in concrete terms. When your brand mentions in LLMs increase, does branded search traffic follow? Does social engagement move with your AI visibility? Those are the questions that separate LLM visibility that has genuine business impact from visibility that is simply vanity. SE Ranking gives you the data correlation layer to tell the difference, and to communicate that difference to the stakeholders who need to act on it. A Platform That Grows as Your Work Grows As AI reshapes how your audience finds you, your visibility tracking keeps pace. The AI Search Toolkit tracks your brand and domain visibility across AI Overviews, AI Mode, ChatGPT, Perplexity, and Gemini. You can benchmark against competitors, follow how your share of visibility shifts over time, and set up daily tracking to catch changes as they happen — not after the fact. When your workflows move beyond dashboards, the SE Ranking API moves with you — feeding your custom reporting pipelines, your BI environment, and whatever data infrastructure your team has built. And as AI-powered workflows become more central to how modern marketing teams operate, MCP (Model Context Protocol) support means your live keyword, backlink, competitor, and LLM visibility data is available directly inside AI assistants like ChatGPT, Claude, and Gemini — without manual export steps in between. The underlying datasets and algorithms are continuously refined. What you are looking at reflects the real and current state of search, not a lagging approximation. The Infrastructure to Navigate Complexity — and Prove Value of Your Work The hardest part of marketing in this environment is not just doing the work. It is making the complexity legible to the people who need to act on it — clients, executives, and boards who want to understand what LLM visibility is actually worth and where the ROI lies. SE Ranking gives you the reporting infrastructure to answer those questions with data rather than assertions. Your performance reviews become faster to run and easier to defend. Your strategic recommendations connect search and AI visibility to business outcomes, not just traffic numbers. White Label reporting, collaborative project management, and the Agency Pack's extended client seat and reporting capabilities give your operational foundation room to scale without scaling your overhead at the same rate. The search ecosystem is more complex than it has ever been. SE Ranking — together with SE Visible and Planable — is the platform that makes it legible, connected, and actionable, built for the teams responsible for making sense of it.

### [DiffHook](https://www.g2.com/products/diffhook/reviews)

DiffHook is a web monitoring tool that automatically watches any website for you and sends you an alert the moment something changes. Whether it is a competitor updating their prices, a government page publishing new regulations, or a product coming back in stock or even an RSS feed, DiffHook catches it right away so you never miss what matters. You simply tell DiffHook what to watch and how often to check it. It runs quietly in the background, comparing each new version of the page to the previous one. When it spots a difference, it notifies you through the channels you already use: email, Slack, Discord, Telegram, or any other tool in your workflow. DiffHook is used by businesses, researchers, and teams of all sizes to stay on top of external changes without having to manually check websites themselves. It saves time, reduces the risk of missing critical updates, and turns the open web into a reliable source of real-time information for your team.

### [Thieves](https://www.g2.com/products/thieves/reviews)

Thieves is an AI website tracking agent. Just enter the URL of the website you want to track, your natural language condition such as "alert me when there is a research article involving both AI and agents", and the checking frequency. Once your condition is met receive an alert via email, Telegram, Discord or webhooks. Potential Applications currently are • Waiting for the price of a product to go down • Looking for a new property to rent or buy • Looking for a new job • Waiting for the best deal from multiple suppliers • Tariffs announcements • New product release and or price change from competitors • New AI paper in specific sub field and specific application • New model released on Hugging Face • Accommodation deals • Financial update from a company you have a stake in • News relevant to your particular needs • And on and on …….. The Core Problem We Are Solving Each of these above activities currently means you have to actively click, type, tap, load websites, navigate websites, focus out the noise (such as advertisements) and spend significant amount of time just to get the knowledge of what you waiting for has happened or not. You do this multiple times and tomorrow you do it all again. Consistently looking and navigating websites multiples times per day cost time and focus which also equals money!!! Not doing the manual checking each day means you miss out on opportunities. People make trade offs with the amount of time they are willing to actively periodically search websites and the best opportunity. The Solution Thieves AI agents automatically monitors websites periodically for you, looking for your natural language conditions, alerting you when your condition is met. AI agents can check more times per day than you can getting valuable information you may have missed with manual checking. You can take action on new information released on websites straight away. We are also allowing users to automate actions once their conditions are met with our REST API and webhooks.
