February 2023 A shorter month and a drop in post-holiday fleet repairs led to less trade audience data than January, but last mile vehicle technician audiences were still up compared to November and December.

January 2023 We saw a 20% increase in the last mile vehicle audience which makes sense since those vehicles spent so much time on the road during the holiday delivery season in December. There was also a significant increase in the fleet manager audience, also not unexpected.

December 2022 We’ve tracked the last mile vehicle technician audience for 3 months now. The data is consistent with an expected continued increase in fleet managers researching electronic logging issues. Other trade audiences are similar to November. Consumer audience categories saw a few drops compared to November except for shocks which were up a bit. Wiper blades really jumped, likely due to the “cyclone bomb” weather that hit much of the country.

November 2022 Our first two months of data for last mile vehicle technicians is consistent between November and October. This month, we saw a significant jump in fleet managers researching electronic logging device issues and added the category below. Consumer audiences saw a slightly downward trend as the holidays approach. That’s consistent with data from pre-Covid years.

October 2022 This month we added Last Mile Vehicle audiences and two very specific examples of focused application specific fleet audiences. Consumer data shows strong demand continuing in brakes categories while most other categories were slightly down from a strong September.

September 2022 The brakes category performed very well in September and tire replacement rose significantly. That apparently impacted the TPMS trade audience with numbers higher than they were in August.

August 2022 In all, August looked like a good month for the aftermarket and that bodes well for the fall season. There was strong growth in several categories with brake repair and replacement taking the lead. As a matter of fact, this audience was the biggest we’ve seen since April of 2019! Our trades audiences grew significantly in most categories as well.

July 2022 Last month there were significant increases in consumers researching brake replacement, wheel end, and performance brakes. Our brake replacement audience is the biggest we’ve seen this year. A general lift in Last Mile vehicle parts buyers and fleet managers audiences is also apparent.

June 2022 Trade audiences were relatively flat in June with some showing slight decreases. We saw a big jump in the car detailing audiences which is expected this time of year. There was also significant increases in the tire replacement and check engine light audiences as consumers prepare for summer vacation road travel.

May 2022 Both our trade and consumer audiences are trending slightly lower than we’ve seen in recent months. This may be due to the general impact gas prices and inflation are having on the aftermarket. With Summer driving season starting, it will be interesting to review the June and July numbers.

February 2022 Across the board numbers were down a bit from January. However, even with a shorter month there was a continued increase in consumers researching CHECK ENGINE LIGHT. February marks the beginning of pothole season, so we see an expected seasonal jump in the shocks, suspension and chassis categories.

December 2021  The research on consumers researching parts and service was relatively flat compared to last month. The Battery and Wiper Blade categories went up, however, and the Detailing category went down. The repair professional data shows a significant increase in the audience of Fleet Managers since this audience includes the managers of last mile fleets.

October 2021  Some parts categories continue to outperform: Fuel delivery, wheel end, chassis, and belts & tensioners. Our audience of tech researching complex diagnostic issues is also up over 30% from last year, and 6% above Oct 2019 numbers. It will be interesting to review repair order data to see if average ROs increased as the data suggests it might.

September 2021  Most categories continued to lag 2019 data but exceeded the 2020 numbers. As they did last month, the categories that continue to see significant increases in online research by consumers are Fuel Pumps, Hubs and Bearings, Serpentine Belts and Chassis DIFM. We tracked 10 chassis specific audiences and saw significant increases last month in the technician and DIY audiences researching ball joint, tie rod and steering linkage issues. Any feedback from readers regarding this trend would be appreciated.

August 2021  When comparing August 2019, 2020 and 2021, we found that for most categories, online research this year met or exceeded that in August 2019. There were significant increases in the fuel pump, hubs and bearings and chassis DIFM categories.  Combined with an increased diagnostic specialist audience, this may indicate higher ROIs for shops in August.

September 2020  Although online research dropped for many categories, we saw a big lift in consumer wiper blade and fleet manager audiences. The impact of sales promotions and industry regulation changes seem to be why.

JANUARY 2020  As we expected, all the numbers for January are up compared to December, except for Fleet Managers. That is entirely due to a significant drop in research on ELD. The mandate’s final date for implementation was 12/16/19, so this makes sense.
