When was the last time you searched online for your website? Since it is likely the first thing your prospective customer will do, it will set the tone for their experience. Imagine if the first thing they saw was “Warning: Visiting this site may harm your computer”?
Your website may completely function, but website search engines have identified potential problems. What should you do? This is a job for your website administrator, since it likely involves the low level details of your website.
What would they do? They’d first visit a diagnostic page – a report on specifically what the search engine detected as a problem. Based on the report, they’d likely disable some “infected” parts of the website (areas that a hacker has modified), carefully remove all the “damaged” parts (if you don’t remove all the infection, the problem will reoccur), and reinstall “clean” (non-infected) tools. They may change your passwords. It may take minutes or days depending on the severity of the problem.
Finally, when it appears to be fixed, they would notify the website search engine(s) that the problem is fixed. If their software no longer detects the problem, they will remove the “Warning: Visiting this site may harm your computer” message.
You want your prospective client’s experience to be: “Warning: Not buying from this website will harm your life”!
