DetailsVisit site

Social Blade is a social-channel analytics site and API for tracking public creator statistics across YouTube, TikTok, Twitch, Instagram, Facebook, and X/Twitter. It has large branded and YouTube analytics demand, making it useful as alternative data for creator-economy, media, advertising, influencer, and platform research. Free profiles are useful for quick checks, while Premium and Business API tiers expand history, favorites, top lists, report cards, exports, and API credits. It is not a source of private platform data, company fundamentals, portfolio analytics, broker execution, or investment recommendations.

Similarweb is a digital intelligence and website traffic analytics platform for researching web traffic, app usage, keywords, referrals, competitors, companies, technologies, and online market share. For investors, it provides alternative data for digital businesses such as marketplaces, ecommerce, SaaS, media, travel, and consumer internet, not reported financials. Meaningful API, history, exports, integrations, and enterprise workflows are paid or custom. It is not a broker, portfolio tracker, valuation model, fundamentals terminal, or direct source of company revenue.

Public charts and app lookup tools support lightweight discovery; commercial workflows use Sensor Tower Connect, APIs, scheduled feeds, Snowflake, Salesforce, Slack, and custom alerts. It is not a stock screener, fundamentals database, portfolio tracker, broker, or direct source of reported company revenue.

TickerTrends is an alternative-data and KPI-forecasting platform for public-company investors, analysts, quant teams, hedge funds, and institutions. It combines search, web traffic, app usage, social, reviews, news, transcripts, financial data, consensus, and proprietary trend signals, but those signals are noisy proxies that require validation before investment use.

Semrush

Semrush is an SEO, marketing intelligence, website traffic analytics, and AI search visibility platform that investors can use as alternative data for search-dependent companies, publishers, agencies, ecommerce, SaaS, and consumer brands. It supports keyword demand, competitor visibility, traffic proxies, and channel analysis; these modeled signals require validation against filings and first-party metrics. It is a marketing platform rather than investing software, not a broker, portfolio tracker, valuation model, official fundamentals provider, or direct measure of company revenue.

It fits users searching for a free stock screener or alternative data screener, especially when they want nontraditional signals before checking filings and fundamentals. Optional sign-in adds personalized feeds and alerts, and the site offers embeddable earnings-calendar widgets. It is not a broker, portfolio accounting product, enterprise data feed, or source with verified SLA and freshness guarantees.
