Absolutely.  As I've said for the past decade or so--"People shop online but buy with a Realtor."  I think online shopping easily eliminates properties that don't meet the needs of buyers, and save everybody a bunch of time.

OH ABSOLUTELY . . . you can see the property and area so easily, that it's easy to zero in or rule out. 
20+ years back I went out and previewed properties for buyers by the handfuls, so I could do the same thing that technology does for us now!

There is no average. The only reason I show fewer homes now is because of lack of inventory. During the Great Recession there was lots to show. My buyers would look at more home now if they could. I always tell clients the internet is a good way to eliminate homes, but if there's something they are interested in they need to see it first-hand and in the context of the street, the neighborhood, the area.

I got into real estate just before the 2008 crash when an out of towner would want to see as many homes as possible in a day, and then sometimes not even wanting to get out of MY car (yes, I drove them around) if the outside didn't appeal to them.  At the end of the day, more likely than not, they made a decision on which one to make an offer on.  

Now it's totally different.  Buyers have done their homework with the help of great photos.  They do their own research in most cases.  

All real estate is local.  My focus is on investment properties or second vacation homes.  I focus on communities/subdivisions or condo complexes.  I don't mind doing drive by tours of these areas but it would be impossible to show more than one or two units during the season.  50 homes  never.  

I retired 5 years ago Joan Cox but even then showings were dropping down. I also manned a model home and walk-ins were down as most people checked it out on line prior to coming to see the model.

Gone are the days when buyers would ask, "Can I see your MLS book?"

 Many buyers shop online, then weed out the properties that they don't like.  This can be advantageous to Realtors (less time wasted).

I wish there were more homes to show! Online viewing definitely eliminates some homes, but it's never the same as seeing them in person and in the context of the neighborhood and the home setting.

The few buyers I have are seeing less homes also, last one was only 6

So many things change and this be one of them. I would show only the homes that they think is a doable, possible purchase. Online, Google etc., does all the looky loo stuff. Of course, that's after they have proven themselves to buy ala vetting

Back in the days when I actively worked with buyers, it was not uncommon to show a lot of homes, write offers that were outbid, continue showing more homes, rinse, and repeat.  

The last buyer that I worked with was a referral from an AR friend.  They were targeting one community.  I showed all available homes, 5-6. 

We always do a preliminary showing online in the office to narrow down the search before ever leaving the office.

I so enjoy the efficiency of the modern tools.

I try to show fewer homes. I don't want to go back to the recession times. I showed way too many homes back then. Inventory is lower but buyers are looking further our. So, there are some times I feel we're showing too many. 

My goal is to educate them more on the first outing so that they better screen/assess things online.  I probably show 3 - 8 homes before it's "the one" unless they're looking for a niche property or are just "those" type.  ;0 

I showed one couple 62 homes...! 

Retired, parked, and reading. My guess is less because so many are eliminated based on the descrioon and photos posted online.

People use the internet as a screening tool but still need to see the same number of homes before purchasing.

I think that is better now that clients can hone down homes that won't fit their needs by the videos & pictures. I think that we have really stepped that up for the consumer.

I would not show 50 homes - at 20 we part ways.

I don't believe internet changed the number of homes.  Inventory certainly has.

With a virtual office, you and I are "showing" properties, sharing local information more than ever. If you embrace technology. Your audience is larger, your reach is longer and the real estate day never stops online. 

To your point, yes. I think we waste less time showing clunkers.

But, also low inventory makes each showing 1-2 homes instead of 6 at a time like back in our SoCal 2012-2018 era.

It's definitely helped, but people still want to walk through properties before they buy a principle or second home.

I showed 3 today and with this buyer, in years past, it would have been 6-10. We simply have painfully low inventory so, in every price range, there are FAR fewer to tour than say, during The Great Recession. 

To your point though, many buyers tour homes online first and eliminate homes as a result. Back in the day, there were very few walk-through tours and only a few photos were allowed in the MLS. 

As to the 50 homes - oh my gosh, that is ONE thing I don't miss about those days! LOL
