We connected SESTEK's Webflow forms not straight to the CRM but to a Webflow Cloud app on the site's domain; only this server layer talks to Microsoft Dynamics 365, and the browser never does. The forms are React code components managed from the Designer, on a bilingual CMS whose folder and item slugs are largely translated. [SESTEK: how we connected Webflow forms to Dynamics 365](https://www.roicool.com/en/case-studies/sestek-webflow-cloud-dynamics-365-integration) ### Modaltrans SEO case study: organic and AI visibility Modaltrans.

[MEP: A Premium Webflow Showcase for Turkey's Leading DMC](https://www.roicool.com/en/case-studies/mep-premium-webflow-showcase) ### Royal Hair: how did we split a $60,000 budget between two different jobs? Royal Hair. At Royal Hair, Google Ads captures demand that already exists while a multi-stage Meta funnel carries cold audiences toward a booking. A $60,000 monthly budget is balanced between those two jobs, and CAPI keeps conversion data clean at every stage. The published results: 14x average ROI, an 8% conversion rate and an $11 lead cost, which can vary seasonally. [Royal Hair: how did we split a $60,000 budget between two different jobs?](https://www.roicool.com/en/case-studies/google-meta-multi-stage-funnel) ### Performance marketing optimization: 150% increase in appointments Serkan Hezar. With our data-driven performance marketing strategy for our partner in the healthcare sector, Serkan Hezar Clinic, we maximized lead quality without increasing the advertising budget and increased the number of actual appointments by 150%. [Performance marketing optimization: 150% increase in appointments](https://www.roicool.com/en/case-studies/healthcare-appointment-optimization) ### How did we split campaigns in a clinic with a broad service range? EsteMoon Clinic. EsteMoon Clinic's services span hair transplants, dental work and aesthetic treatments; we split the campaigns to match that breadth, at service-line level. On the organic side, SEO runs in 10 languages. A $150,000 monthly budget is spread over that structure. [How did we split campaigns in a clinic with a broad service range?](https://www.roicool.com/en/case-studies/service-line-campaign-split) - [All case studies (9)](https://www.roicool.com/en/case-studies) ## Comparisons, the same criteria. ### Apollo.io vs Clay: which for B2B data and outbound? 8 min read. Apollo suits sales teams that want to pull lists from a ready database, send sequences from the same tool and keep a predictable per-user cost. Clay suits teams that combine several data providers, research accounts with AI and build custom workflows into the CRM, and have the GTM engineering capacity to run them. [Apollo.io vs Clay: which for B2B data and outbound?](https://www.roicool.com/en/comparisons/apollo-vs-clay) ### Apollo vs Lemlist: which one for outbound? 1 min read. Apollo suits sales teams that want a large B2B database, enrichment and sequences in one tool to build their target list. Lemlist suits teams whose list is largely ready and who focus on personalised, multichannel sequences. In both, deliverability depends on your sending infrastructure. [Apollo vs Lemlist: which one for outbound?](https://www.roicool.com/en/comparisons/apollo-vs-lemlist) ### GA4 vs Mixpanel: marketing or product analytics? 1 min read. GA4 fits marketing and acquisition analysis: traffic sources, campaign performance and the Google Ads integration. Mixpanel fits product analytics: what users do inside the product, cohorts and retention. Many SaaS companies use both side by side, with the same event names and user IDs in each tool. [GA4 vs Mixpanel: marketing or product analytics?](https://www.roicool.com/en/comparisons/ga4-vs-mixpanel) ### GEO vs SEO vs AEO: the differences and when to use each 2 min read. SEO gets a page ranking in search results; AEO structures the page so it answers a specific question directly; GEO aims to have the brand and the page chosen as a source in AI answers, off-site sources included. They are not alternatives: SEO is the foundation, and AEO and GEO build on it. Our GEO agency service runs all three. [GEO vs SEO vs AEO: the differences and when to use each](https://www.roicool.com/en/comparisons/geo-vs-seo-vs-aeo) ### Google Ads vs Meta Ads: which channel, and when? 1 min read. Google Ads fits when people already search for what you offer and you want to capture that demand. Meta Ads fits offers where demand does not exist yet, that can be shown visually and need to reach a broad audience. Most brands run both, and decide with qualified-lead and sales data from the CRM. [Google Ads vs Meta Ads: which channel, and when?](https://www.roicool.com/en/comparisons/google-ads-vs-meta-ads) ### Google Ads vs Microsoft Advertising: which one fits which business? 8 min read. For almost any business selling to customers in Türkiye, Google Ads is the main search channel. Microsoft Advertising makes sense as a second channel for B2B companies that already run well-measured Google campaigns, sell into markets such as the US or UK, and want extra search volume for little extra work by importing those campaigns. [Google Ads vs Microsoft Advertising: which one fits which business?](https://www.roicool.com/en/comparisons/google-ads-vs-microsoft-ads) - [All comparisons (16)](https://www.roicool.com/en/comparisons) ## Digital marketing glossary. ### What Is User Experience (UX)? The Complete A-to-Z Guide User experience (UX) is the sum of all the perceptions, emotions and experiences a person has when interacting with a product, system or service; it covers usefulness, efficiency and accessibility. UI is about how a product looks, while UX is about how it works and how it feels. It has a direct effect on customer loyalty, conversion rates and development costs. [What Is User Experience (UX)? The Complete A-to-Z Guide](https://www.roicool.com/en/glossary/user-experience-ux) ### What Is a Keyword and Why Does It Matter So Much? A keyword is the word or phrase a user types into a search engine; it can be a single word or a longer phrase of several words. These terms drive the targeting of both SEO content and PPC campaigns. Because keywords are grouped by length and user intent, choosing the right ones affects ad budget efficiency as much as visibility. [What Is a Keyword and Why Does It Matter So Much?](https://www.roicool.com/en/glossary/keyword) ### What is a Lead? The Concept of a Potential Customer and Its Importance in Marketing A lead is a potential customer who has shown interest in a business by sharing contact details or engaging in a way that signals future buying intent. Leads sit at the first stage of the sales funnel: they are not customers yet, and how they are qualified and followed up decides how many ever become one. [What is a Lead? The Concept of a Potential Customer and Its Importance in Marketing](https://www.roicool.com/en/glossary/lead) ### What is Call-to-Action (CTA)? Comprehensive CTA Guide to Increasing Your Conversion Rate A call to action is the element that tells a visitor exactly what to do next — buy, subscribe, download or get in touch. It is the bridge between interest and action, and it carries the whole weight of a page's conversion goal. A CTA can be a button, a link, a line of text or a form. [What is Call-to-Action (CTA)? Comprehensive CTA Guide to Increasing Your Conversion Rate](https://www.roicool.com/en/glossary/cta) ### What is ROI? The Ultimate Measure of Profitability Return on investment measures how much profit an investment produced relative to what it cost. Expressed as a percentage or ratio, it answers a single question: for every unit spent, how much came back as profit? Its simplicity is why it travels across departments, and also why it hides things worth knowing. [What is ROI? The Ultimate Measure of Profitability](https://www.roicool.com/en/glossary/roi) ### What is a Landing Page? A Guide to Creating High-Conversion Landing Pages A landing page is a standalone page built for one marketing campaign and one goal. Unlike a website, which invites exploration, a landing page removes choices so the visitor can only convert or leave. It is where paid traffic arrives, and its single-mindedness is the reason it converts better than a general page. [What is a Landing Page?

It gives October 2026 pricing for HubSpot, Zoho CRM, Salesforce, Bitrix24 and Pipedrive as each vendor's own page states it, and follows a CRM project in order, from needs analysis to migration and adoption. There is no "best CRM" pick and no unsourced statistic. [Choosing and migrating a CRM: HubSpot, Zoho, Salesforce, Bitrix24, Pipedrive](https://www.roicool.com/en/ebook/crm-selection-and-migration-guide) ### Google Ads account audit: a 40-point checklist A step-by-step audit workbook for businesses that run their own Google Ads account.

Every rule is sourced to the Google Ads Help Center. [Google Ads account audit: a 40-point checklist](https://www.roicool.com/en/ebook/google-ads-account-audit-checklist) ### Medical tourism digital marketing guide (with Türkiye's 2026 advertising rules) A guide for the marketing teams of clinics and hospitals that treat patients from abroad, bringing Türkiye's health rules, the ad platforms' policies and patients' expectations into one way of working. The rules are read from the Official Gazette text, with article numbers; the platform rules come from Google's and Meta's own policy pages. It is not legal advice and promises no results. [Medical tourism digital marketing guide (with Türkiye's 2026 advertising rules)](https://www.roicool.com/en/ebook/medical-tourism-digital-marketing-guide) ### New era in SEO: what is AEO and what to do Are you tired of hearing the phrase “SEO is dead”? Let's focus on the real question: What are the new rules? With the rise of artificial intelligence (AI) search engines (AEO): Which old SEO tactics no longer work? What needs to be done to look “expert” and “trustworthy”? Who should we write our content by now: Human or AI? “Is backlink important?” Read our research in which we examine all these questions one by one. [New era in SEO: what is AEO and what to do](https://www.roicool.com/en/ebook/new-era-in-seo-what-is-aeo) ### AI visibility: a guide to measuring and improving it Buyers now start their supplier research in ChatGPT, Gemini, Claude, Perplexity and Google's AI answers. This guide shows how to measure, with a repeatable method, whether your brand is mentioned in those answers, and how to close the gaps the measurement reveals, in order.
