This is probably what you might be referring too and yes a proportion of fear mongering works, but at the end of the day there are some serious muppets out there who will just book any old DJ based on the cheapest quote and not ask any questions or get in touch until a week before the wedding date. If I booked a builder and had a well written simple checklist bible to work from then getting the right one would be much easier. I have had client relay my list back to me at meetings, not knowing that I wrote it LOL. Its nice to steer people in the right direction as more often than not this is the first event they have ever managed. Plus as you say its a plus point when Google goes through the site as its relevant and rich in keywords or whatever??
