Features and specs

What each product offers, as listed by its team.

IsItIndexed 3 features
Modular JavaScript 5 features
  • User-Friendly Interface
    IsItIndexed offers a clean and simple interface that makes it easy for users to quickly check whether a webpage is indexed by search engines. This accessibility ensures that even those with limited technical knowledge can use the tool effectively.
  • Fast Results
    The tool provides rapid results, allowing users to instantly know the indexing status of their pages without having to wait for long processing times.
  • Multiple URL Checks
    IsItIndexed allows users to check multiple URLs in a single session, streamlining the process for those who need to check the indexing status of several pages at once.

Possible disadvantages

  • Limited Search Engine Support
    The tool may only support a limited number of search engines, potentially excluding smaller or regional search engines, which could be a drawback for users targeting a broader audience.
  • No Additional SEO Insights
    IsItIndexed is primarily focused on checking the indexing status, without providing additional SEO insights or recommendations, which could be a limitation for users seeking comprehensive SEO analysis.
  • Dependence on API Availability
    The accuracy and reliability of IsItIndexed depend on the availability and stability of external search engine APIs, which could occasionally lead to inconsistencies or downtime.
  • Improved Code Organization
    Modular JavaScript allows developers to break down code into smaller, manageable modules. This enhances code readability and maintainability by organizing related functionality together.
  • Code Reusability
    Modules encourage reusability by allowing the same piece of code to be used across different projects or multiple areas of the same application, reducing redundancy.
  • Scalability
    As the application grows, managing code becomes easier with modular JavaScript. Each module can be developed, tested, and maintained independently, making the codebase more scalable.
  • Encapsulation
    Modules provide encapsulation, preventing variables and functions from polluting the global namespace. This reduces the risk of naming conflicts and bugs.
  • Improved Testing
    With code organized into discrete modules, writing unit tests becomes more straightforward. Each module can be tested individually, leading to more reliable and maintainable tests.

Possible disadvantages

  • Increased Complexity
    Introducing modularity can add complexity to the build process, as it often requires module loaders or bundlers (like Webpack or Browserify) to manage dependencies.
  • Overhead
    For smaller projects, using a modular approach might be overkill, introducing unnecessary overhead in terms of setup, configuration, and code management.
  • Learning Curve
    Developers unfamiliar with modular JavaScript may face a learning curve, especially when dealing with module patterns, loaders, and bundlers.
  • Dependency Management
    Relying on multiple modules can lead to complex dependency chains, making it challenging to track and resolve dependencies across different modules.
  • Performance Overhead
    Modular JavaScript can introduce performance overhead if not managed properly, such as loading many small modules individually, leading to increased HTTP requests.

Questions & Answers

As answered by people managing IsItIndexed and Modular JavaScript.

What makes your product unique?

IsItIndexed's answer

Most SEO tools tell you whether a page is indexed. That's a yes/no answer, and if you already know your page isn't indexed, it tells you nothing. IsItIndexed runs 13 diagnostic checks to figure out why Google won't index your page and what to fix first. It also checks whether AI platforms like ChatGPT, Claude, and Perplexity can find and cite your content. No other single-URL tool combines Google indexability diagnostics with AI visibility checks.

Why should a person choose your product over its competitors?

IsItIndexed's answer

  • No account, no signup, no monthly subscription
  • Paste a URL and get a prioritized report in seconds
  • Free scan covers 4 technical checks
  • Full report is a one-time $4.99 and covers content quality, structured data, page speed, sitemaps, and three AI visibility checks that no competing tool offers
  • SEO agencies charge $500+ for audits covering similar ground
  • The cheapest monthly tools start at $50

How would you describe the primary audience of your product?

IsItIndexed's answer

Site owners, solo founders, bloggers, and freelance SEOs who are stuck in "Crawled, currently not indexed" limbo in Google Search Console. People who know something is wrong but don't have an SEO team to diagnose it. Also useful for anyone who wants to check whether AI search engines can actually find their content.

What's the story behind your product?

IsItIndexed's answer

Google's June 2025 core update pruned an estimated 15-20% of the index. More pages than ever are stuck in "crawled but not indexed" and existing tools only check whether you're indexed, not why. At the same time, AI crawlers showed up and nobody had tooling to check visibility across those platforms either. I built IsItIndexed to close both gaps in one scan.

Which are the primary technologies used for building your product?

IsItIndexed's answer

  • Next.js and TypeScript on the frontend
  • Cheerio for HTML parsing
  • All 13 diagnostic checks are rule-based with no LLM anywhere in the pipeline
  • Supabase for report storage
  • Stripe for payments
  • Hosted on Vercel
