I want to ask those who have ever encountered or may be aware of such a situation.
We are operating since 1998 and our decent size of business comes from web inquiries (request for quotation forms and contact us forms) due to good ranking in google pages. But recently we are facing a big drop in web inquiries and this is to the tune of a 90% drop in some months. Strange thing is that our website traffic has not dropped (only 10-20% drop in some months but recovered in other months). Please note, We haven't updated our site in this period.
Website visitors are coming to contact us and quotation forms but not sure why there are no inquiries at all. For reference, I am adding 1-month traffic small snapshot which shows a comparison to the same month last year but last year same month we received more than 15 inquiries, this year only 1. We have an SEO expert inhouse but he too is not able to find any reason for this phenomenal change because nor our business changed nor our traffic. Also note, it's not an HTTP to HTTPS conversion issue because that went smoothly and as I said our traffic didn't drop phenomenally like the inquiries.
Can anyone of you geniuses knows or discover what could be the issue?
