As an IT professional who is responsible for the support, security and SEO ranking of your website, I feel it necessary to inform you that a home-made engine from a programmer without a rating cannot be used. This can be a big problem in the long term.
Security and Stability (Highest Risk)
| Risk | Description |
|---|---|
| Critical Vulnerabilities | Home-written code rarely passes an independent security audit. Probability of presence hidden "holes" (SQL injections, XSS attacks) is very high, which makes the site an easy target for hacking. |
| Lack of Updates | Popular CMS regularly release security patches in response to new threats. An unknown developer will not do this. Your site will **quickly become outdated** and vulnerable. |
| Dependence on one person | If the programmer disappears or asks for an exorbitant fee, you will find yourself in a **dead end**. No one else will want (or be able to quickly) understand unique, poorly documented code. |
Support and Development (High Costs)
- Dear Support: Any new specialist will spend much more time and money to study an unfamiliar architecture than to work with a well-known CMS (WordPress, OpenCart, etc.).
- Slow Development: Adding new, standard functions (for example, integration with CRM, online payment, mailing services) will require expensive development from scratch, while for popular systems there are ready-made, tested plugins.
- Difficulties with Hiring: Finding a new developer who will take on a “legacy” self-written engine is **extremely difficult** and expensive. The market is oversaturated with specialists in popular technologies.
SEO Problems (Loss of Clients)
- Poor Performance: Loading speed is a key ranking factor (Core Web Vitals). Unoptimized home-written code is often works slowly, which worsens the user experience and **reduces rankings** in Google. [Image of Core Web Vitals performance metrics]
- Lack of SEO tools: You will have to improve basic functions such as managing meta tags, creating clean URLs, setting up a sitemap $sitemap.xml$ and robots.txt. In standard CMSs this is **built-in or easily added**.
- Problems with Indexing: Incorrect structure or errors in the code may prevent Google and Yandex search robots from correctly reading and indexing your content.
Quick Summary: False Economy
Using a custom engine is trap. You save a little initially, but you overpay many times over in the long term for:
- **Constant risk of hacking** and data loss.
- **Exorbitantly expensive** and difficult to support.
- **Loss of traffic** due to poor SEO and slow performance.
We must build the site on a **proven, secure and scalable** platform.
