Most websites lose over 90% of their visitors without ever capturing a single contact detail. Those visitors had questions, but no one was there to answer them at 2 a.m. on a Tuesday. A lead generation chatbot fixes that - and according to Tidio research, 60% of businesses report that AI chatbots have helped them generate more qualified leads.

This tutorial covers how to build a lead generation chatbot using SiteGPT - from creating an account to going live on a website. The result is a chatbot that answers visitor questions, qualifies interest, and collects contact details automatically, without requiring any third-party integrations or coding skills.

TL;DR: Create a free SiteGPT account, train the chatbot on the website's content, set the Sales Expert persona, add custom lead gen instructions, enable native lead collection, and paste one JavaScript snippet onto the site. Total setup time: 20-30 minutes, no coding required.

What You'll Build

By the end of this tutorial, readers will have:

A trained AI chatbot that answers questions using their website content and product information

Native lead collection that captures visitor names, emails, and custom fields - no Google Sheets or Zapier required

A deployed chatbot that works on WordPress, Shopify, Squarespace, Wix, Webflow, or any custom HTML site

Time to complete: 20-30 minutes

Difficulty: Beginner

What you'll need: A SiteGPT account (free trial available), access to the website's HTML or CMS

Why Lead Generation Chatbots Work

Lead generation chatbots outperform static contact forms because they engage visitors in conversation, answer questions in real time, and ask for contact details only after demonstrating value - a sequence that produces higher opt-in rates across most industries.

Higher Conversion Rates

Chatbot-led funnels convert at a higher rate than static web forms because the interaction is two-way. When a visitor asks a question, the chatbot responds with useful information and then asks for contact details in a natural, conversational way - answer first, ask second. This sequence performs better than a form that asks for personal information before providing anything in return. According to Tidio, 64% of businesses that adopted AI chatbots reported an increase in qualified leads, compared to their previous form-based capture methods.

24/7 Lead Capture Without Extra Headcount

A lead generation chatbot captures leads at all hours without requiring staff to be available. Sales teams are offline evenings, weekends, and across time zones - a chatbot running on the website means inquiries from those windows are captured rather than lost. For businesses running paid ad campaigns outside business hours, this is a direct revenue impact: every click that lands on a website after hours either converts or leaves.

Lower Cost Per Lead

A configured chatbot handles the same qualifying conversation repeatedly at no incremental cost per interaction. Unlike paid retargeting or manual outreach, the marginal cost of each additional conversation is zero. Once trained and deployed, the chatbot answers questions, collects contact information, and notifies the sales team continuously - without additional spend per lead captured.

Why SiteGPT Works Well for Lead Gen

SiteGPT is best suited for businesses that want a lead generation chatbot trained on their own content, with native lead capture, without connecting third-party tools.

The most relevant feature for lead generation is native lead collection. SiteGPT captures visitor names, emails, phone numbers, and custom fields directly inside the chat conversation - no Google Sheets, Zapier, or external CRM connection is required. When a lead is captured, the platform sends an email notification and can automatically hand off to a human agent. That entire workflow is built in.

SiteGPT also includes a built-in "Sales Expert" persona - described as "Persuasive and results-focused, great for converting visitors into leads." Combined with custom instructions that define the chatbot's specific goal, this persona shifts the chatbot's behavior from generic question-answering to active lead qualification.

The setup takes under 30 minutes and requires no technical background. As one verified G2 user put it:

"SiteGPT makes it easy & intuitive to get your chatbot setup & working in no time at all - anyone can do it." Verified User, G2

Step-by-Step: How to Build a Lead Generation Chatbot with SiteGPT

The full setup takes under 30 minutes and requires no coding. Each step below includes a time estimate and a screenshot of exactly what to click.

Step 1: Create Your SiteGPT Account and Chatbot (~2 min)

To start, create a free SiteGPT account and set up a new chatbot - no credit card required.

Go to SiteGPT and sign up for a free account

From the dashboard, click "Create Your Chatbot Now"

Give the chatbot a name - something recognizable like "Acme Sales Assistant" or "Get a Quote" works well for lead gen

Set a welcome message that matches the goal, for example: "Hi! I can answer your questions and help you find the right plan. What are you looking for?"

Pro tip: Use the welcome message to signal what the chatbot can do. A welcome message that says "I can answer questions about pricing, features, and plans" pre-qualifies visitors and gets more engagement than a generic "How can I help you?"

Step 2: Train Your Chatbot on Your Content (~5-10 min)

Training connects the chatbot to the business's actual content so it answers questions accurately instead of giving generic responses.

From the dashboard, click "+ Add Links"

Choose "Scrape Website" to pull the entire site automatically, or "Multiple Links" to add specific pages

Add the most important pages first - pricing, features, case studies, and the homepage

For lead generation, the chatbot should be trained on content that helps qualify interest and move visitors toward a decision. Pages with pricing, feature details, and case studies are the highest priority - these are the pages visitors read before they are ready to share their contact details.

What to include for lead gen:

Pricing page (visitors asking about price are often ready to buy)

Features or services pages (helps answer "is this right for me?" questions)

Case studies or testimonials (builds credibility before asking for contact info)

FAQ content (handles objections that might otherwise block conversion)

Step 3: Set the Chatbot Persona (~2 min)

The chatbot's persona determines its tone and approach. For lead generation, the persona should be focused on helping visitors move forward rather than simply answering and closing the conversation.

In the left sidebar, go to Customizations > Chatbot Persona

Select "Sales Expert" from the list of built-in personas

Review the persona description to confirm it matches the goal

The Sales Expert persona is described as "Persuasive and results-focused, great for converting visitors into leads." It keeps responses focused on helping visitors move forward, rather than simply answering questions and ending the conversation.

Step 4: Add Custom Instructions (~5 min)

Custom instructions define the chatbot's specific objective - in this case, to collect contact details from interested visitors. This is what distinguishes a lead generation chatbot from a general-purpose Q&A bot.

Go to Customizations > Chatbot Instructions

Click "Add Instruction"

Write instructions that reflect the business's tone and lead capture goal

Example instructions for lead generation (copy-paste ready):

You are a lead generation assistant for [Company Name]. Your goal is to understand
what the visitor is looking for, answer their questions about our products/services,
and collect their name and email so our team can follow up. Be friendly and helpful.
If a visitor seems interested, ask for their contact details to send them more
information or schedule a call. Never be pushy - focus on being genuinely helpful.

Adapt the company name and adjust the tone to fit the brand. The key elements are: understand the visitor's need, answer their questions, ask for contact details once interest is established.

Step 5: Enable Lead Collection (~5 min)

Lead collection is the core of this setup. SiteGPT handles lead capture natively - visitors submit their details inside the chat conversation itself, with no third-party integration required.

Go to Lead Collection in the left sidebar

Toggle lead collection to "On"

Choose when to collect leads - options include before the conversation starts, after the first message, or when the visitor asks a specific type of question

Select or customize the fields to collect (name, email, phone, company, custom fields)

Choose an industry template if applicable - SiteGPT includes pre-built templates for Dental Clinic, HVAC, Legal Services, Real Estate, SaaS/Software, E-commerce, Consulting, and more

After configuring the fields, set up email notifications so the team is alerted when a new lead is captured.

Go to Notifications and add the email address(es) that should receive lead alerts

Optionally enable auto-escalation - when a lead is captured, SiteGPT can automatically hand off to a human agent for immediate follow-up

Pro tip: Triggering lead collection after the first message - rather than before the conversation starts - typically produces higher opt-in rates. Visitors who have already asked a question are invested in getting an answer, which makes them more willing to share their contact details.

Step 6: Customize the Appearance (~3 min)

Matching the chatbot's appearance to the site's branding makes it look like a native part of the experience rather than a third-party widget.

Go to Customizations > Chat Interface Colors and set the primary color to match the brand

Upload a custom chat icon or choose from the available options

Set the chat widget position - bottom-right is the standard for most sites

Step 7: Deploy to Your Website (~2 min)

Deploying the chatbot requires pasting a single JavaScript snippet into the website's HTML. SiteGPT supports all major CMS platforms without additional plugins.

Go to Installation in the left sidebar

Copy the JavaScript embed code

Paste it into the website's HTML just before the closing `</body>` tag

SiteGPT supports WordPress, Shopify, Squarespace, Wix, Webflow, and any site that allows custom HTML. For WordPress, paste the code using a custom HTML block or the theme's footer settings. For Shopify, add it through the theme editor.

Once deployed, clear the browser cache and open the site in an incognito window to verify the chat icon appears. Test a few questions to confirm the chatbot answers correctly and the lead collection form appears as configured.

Pro tip: Use the JavaScript embed rather than the iFrame option. The JavaScript embed loads asynchronously and does not affect page speed scores.

Tips to Get More Leads from Your Chatbot

Deploying the chatbot is the starting point. These four adjustments consistently improve lead volume and quality after the initial setup.

Tip 1: Place the chatbot on high-intent pages first

Not all pages produce the same lead volume. Pricing pages, demo request pages, and product comparison pages attract visitors who are actively evaluating - these are the highest-converting locations for a lead generation chatbot. Starting there, measuring results, and then expanding to other pages gives clearer data on what works.

Tip 2: Review conversation logs weekly

SiteGPT logs every conversation. Reviewing them weekly surfaces the questions visitors ask most often, the objections that come up before they share contact details, and the points where conversations drop off. Those patterns inform updates to the custom instructions and training content.

Tip 3: Match lead form timing to visitor behavior

The default timing works well for most sites, but testing different trigger points can change capture rates. For e-commerce or SaaS sites, triggering lead capture after a visitor asks about pricing tends to produce higher opt-in rates than triggering it at conversation start. For high-consideration services such as legal or medical, offering to send more information before asking for contact details often performs better than an immediate ask.

Tip 4: Follow up within the first hour

A Harvard Business Review study of 2.24 million sales leads found that firms contacting leads within an hour were nearly seven times more likely to qualify those leads than firms that waited longer. SiteGPT's email notifications include the visitor's contact details and the full conversation transcript, giving the sales team the context to send a relevant, personalized follow-up rather than a generic outreach message.

Frequently Asked Questions

Does SiteGPT offer a free trial for lead generation?

Yes. SiteGPT offers a free trial that allows users to build, train, and test a chatbot before choosing a paid plan. The free trial includes access to lead collection features, so it's possible to run the complete lead generation setup and see results before committing to a subscription.

How does SiteGPT collect leads without a third-party integration?

SiteGPT has native lead collection built directly into the platform. Visitors fill in a form embedded inside the chat conversation - no Google Sheets, Zapier, or external CRM connection is needed to capture names and emails. Leads are stored in the SiteGPT dashboard and delivered via email notifications to the team. For CRM syncing, Zapier integrations are available as an optional add-on.

What information can the lead generation chatbot collect?

The lead collection form can be configured to collect any combination of name, email, phone number, company name, and custom fields specific to the business. Industry templates for Real Estate, SaaS, Legal Services, E-commerce, HVAC, Dental Clinic, and Consulting include pre-built field sets tailored to those industries.

How long does it take to set up a lead generation chatbot with SiteGPT?

Most users complete the full setup - account creation, training, persona and instructions configuration, lead collection setup, appearance customization, and deployment - in 20 to 30 minutes. Training time varies based on content volume, but for a typical website with 20-50 pages the process completes in a few minutes.

Can the chatbot qualify leads before collecting their contact details?

Yes. Custom instructions in SiteGPT can direct the chatbot to ask qualifying questions - budget, timeline, use case, company size - before presenting the lead collection form. This approach produces fewer leads but higher-quality ones, which is a better trade-off for businesses with long sales cycles or high-value contracts.

What happens after a lead is captured?

SiteGPT sends an email notification to the configured addresses with the lead's contact details and the full conversation transcript. The auto-escalation option can hand the conversation off to a human agent in real time, enabling live follow-up for high-value leads immediately after capture.

Will the lead generation chatbot slow down my website?

No. The JavaScript embed code loads asynchronously, meaning it does not block the rest of the page from loading. The chatbot widget appears after the main page content has loaded and has no impact on Core Web Vitals or page speed scores.

How do I know if the chatbot is actually generating leads?

The SiteGPT dashboard shows all captured leads alongside their conversation transcripts. Email notifications arrive immediately when a new lead is captured. Conversation volume, lead capture rate, and frequently asked questions are visible in the analytics section of the dashboard.

Can the chatbot handle lead generation in multiple languages?

Yes. SiteGPT supports multilingual conversations. The chatbot detects the visitor's language and responds accordingly, based on the training content provided. Businesses targeting international audiences can train the chatbot on content in multiple languages to improve accuracy across markets.

Is SiteGPT suitable for lead generation in regulated industries like real estate or legal services?

Yes. SiteGPT includes industry-specific lead collection templates for Real Estate and Legal Services, with field sets appropriate to those industries. Custom instructions can be written to keep the chatbot within appropriate boundaries - for example, directing a legal services chatbot to collect contact details and schedule consultations rather than providing legal advice.

Conclusion

A SiteGPT lead generation chatbot trained on the business's content, set to the Sales Expert persona, with custom instructions and native lead collection enabled, captures qualified leads automatically on every page it's deployed on.

SiteGPT starts at $39/month for a single chatbot with 4,000 messages per month. The highest-return starting point is deploying on the pricing page first - visitors there are already evaluating and are more likely to share their contact details in exchange for answers.
