Web scraping: Automated extraction of structured data from web pages. Livescraper does this against Google Maps, Google Search and arbitrary websites — without you writing scrapers.
Data extraction: Pulling specific fields out of unstructured pages (HTML, PDF, JSON) and normalising them into rows. The job all six Livescraper tools do.
Google Maps scraper: A tool that returns business listings from Google Maps as CSV/JSON — names, addresses, phones, ratings, reviews, websites. Livescraper's flagship product.
Google Maps Place ID: Google's stable identifier for a place (e.g. ChIJN1t_…). Independent of language and address changes — the right key to dedupe places across exports.
Google Business Profile: The free Google product (formerly Google My Business) that lets a business control its Maps/Search listing. The data shown on a GBP listing is what scrapers pull.
SERP: Search Engine Results Page. The page Google returns for a query — organic results, ads, map pack, knowledge panel. Scraping SERPs is how rank-trackers work.
Lead generation: The process of finding potential customers (leads) and capturing their contact info. Livescraper's most common use case.
B2B lead generation: Lead gen specifically targeting businesses (not consumers). Pulling all dentists in Chicago with email + phone is B2B lead gen.
Lead scoring: Assigning a numeric value to each lead based on fit and intent. Helps sales focus on the leads most likely to convert.
Cold email: Outbound email to someone who hasn't opted in. Legal in most jurisdictions if relevant + has a clear unsubscribe; deliverability requires careful list hygiene.
Cold outreach: Any unsolicited contact to a prospect — email, LinkedIn, phone. Cold email is a subset.
Email scraping: Pulling email addresses from websites or Google Maps listings. Livescraper's email tool finds and verifies them.
Email validation: Checking that an email address is real and deliverable — syntax, MX, mailbox ping, catch-all detection. Cuts your bounce rate.
Data enrichment: Adding missing fields to existing records — phone numbers, social profiles, employee count, technology stack. Turns thin lists into rich ones.
Data cleaning: Fixing formatting, removing duplicates, standardising fields. Dirty data ruins outreach; cleaning is non-negotiable before sending.
CSV: Comma-Separated Values. The simplest tabular format — one row per line, columns separated by commas. Livescraper exports default to CSV.
JSON: JavaScript Object Notation. The standard format for API responses. Livescraper's API returns JSON; the dashboard converts to CSV.
API: Application Programming Interface — a structured way for software to talk to software. Livescraper exposes a REST API so you can run scrapes from your own code.
API endpoint: A specific URL inside an API that performs one operation, e.g. POST /v1/scrape/maps. Each endpoint has its own parameters and response schema.
Rate limiting: A cap on how many requests you can make per second/minute. Protects servers from abuse; means scrapers must pace themselves. Livescraper handles this for you.
Proxy: An intermediate server that forwards requests on your behalf — masks your IP and rotates locations. Used by every serious scraper to avoid blocks.
Pagination: Splitting a large result set across multiple pages. Scrapers must follow page links (or scroll) to capture every record.
Review scraping: Pulling every review for a business — text, rating, author, date, owner reply. Livescraper bypasses Google's 5-review limit.
Sentiment analysis: Automatically classifying text as positive/negative/neutral. Useful for review monitoring at scale.
Geocoding: Converting an address into latitude/longitude. Essential for plotting leads on a map or filtering by radius.
Reverse geocoding: The inverse — turning coordinates back into a human-readable address.
CRM: Customer Relationship Management software (Salesforce, HubSpot, Pipedrive). Where leads live after you scrape them. Livescraper exports map cleanly.
Firmographics: Company-level attributes used to segment B2B markets — industry, size, revenue, location, tech stack. The B2B equivalent of demographics.
Data quality: How accurate, complete, fresh and consistent a dataset is. Bad data quality wastes outreach budget; Livescraper's verification stack protects it.
Webhook: An HTTP callback your server receives when an event happens. Livescraper fires a webhook the moment a scrape job finishes — no polling needed.
