Features and specs

What each product offers, as listed by its team.

SubmitDirs 5 features
ALTCHA 9 features
  • Directory Submission Service
    SubmitDirs offers a streamlined service for submitting websites to multiple web directories, saving users the time and effort of manually submitting to each directory individually.
  • SEO Backlink Building
    The service helps website owners build backlinks through directory submissions, which can contribute to improving search engine rankings and domain authority over time.
  • Time-Saving Automation
    Rather than manually finding and submitting to directories one by one, SubmitDirs automates or simplifies the process, making it much more efficient for webmasters and SEO professionals.
  • Affordable Pricing
    Compared to hiring an SEO specialist or agency for link-building campaigns, directory submission services like SubmitDirs tend to be relatively affordable and accessible for small businesses and individuals.
  • Easy to Use
    The platform is designed to be straightforward, allowing users without extensive SEO knowledge to submit their websites to directories with minimal technical expertise required.

Possible disadvantages

  • Limited SEO Impact
    Directory submissions are considered a low-value SEO tactic in modern search engine optimization. Google and other search engines have significantly devalued directory links, meaning the SEO benefit may be minimal.
  • Risk of Low-Quality Directories
    Some directories included in submission services may be low-quality or spammy, which could potentially harm a website's SEO rather than help it if search engines view them as manipulative link schemes.
  • Relatively Unknown Service
    SubmitDirs is not a widely recognized or heavily reviewed platform, making it difficult to verify the quality and reliability of the service before committing to it.
  • Outdated SEO Strategy
    Mass directory submission was a popular SEO tactic in the early 2000s but is now considered largely outdated. Modern SEO strategies focus more on content marketing, quality backlinks, and user experience.
  • Limited Transparency
    It can be difficult to know exactly which directories your site will be submitted to, the quality of those directories, and whether the submissions will actually be approved and result in live backlinks.
  • Privacy-friendly, GDPR compliant
    No cookies, no tracking, no external servers.
  • Frustration-free
    No visual puzzles. PoW Captcha is better for people.
  • Spam Filtering
    Employs machine learning to categorize submitted data and identify unwanted messages.
  • Open-source
    Free to use, free to modify. MIT licensed.
  • End-to-End Encryption
    The Encryption Shield mitigates data breaches by encrypting data with asymmetric end-to-end encryption.
  • Digital e-Signatures
    e-Signatures made easy with eIDAS-compliant simple and advanced signatures - qualified digital certificates and DigiDoc.
  • Visual Form Builder
    Create custom forms effortlessly with the visual form builder, empowering users to design tailored solutions without any coding expertise.
  • File Attachments
    Safely request and securely store file attachments with end-to-end encryption, ensuring the utmost protection for your data.
  • Send to Email or Webhook
    Configure forms to seamlessly send data to email, APIs, or webhooks using processors, facilitating efficient data handling and integration with your workflows.
