Using what Fred mentioned with the anchors. Each service doesn't need a page like mentioned. In fact unless you're going to do adwords and drive traffic to each of those pages then there is no point in creating individual service pages. Create what we call "power pages". More content on one page is better than little content on many pages. We like to organize them by Google category. For instance Carpet Cleaning Service would get carpet, upholstery, tile, rugs, drapery, pet odor removal, mattress cleaning, and carpet/fabric protector information put on it if you offered all those services. If you offer air duct cleaning, create a separate page as there is a Google category for it. On the power pages, use the anchors like Fred mentioned and have the content scroll down to that section. Same for water damage and fire damage, asbestos etc. Then you can create supporting pages for those parent pages if you want.
For instance, for water damage you could have a page created with different types of water damage and talk about basement floods, pipe bursts, dishwasher back up, hot water heater breaks, sewage etc. You URL would look something like yourwebsite dot com/water-damage-restoration/10-types-of-water damage/ which gives you a keyword rich URL.
A carpet cleaning example would be if you wanted to get into the process of pet urine removal you could create a video, as well as take screenshots from the video and write out the process below the video. Then make that page a child of your Carpet Cleaning Service page so your URL would be something like yourwebsite dot com/carpet-cleaning-service/removing-pet-odor-from-carpet/
Here is an example of creating a power page
https://spotfreefloorcare.com/ He had another website before, many other metrics were already in place. We redesigned his website, got rid of all of the unneeded service pages and did 301 redirects to the power page, and added a few other navigational things in place and in 2 days from the new launch he jumped to #3 in the maps from being second from the bottom. He also jumped from page 3 to bottom of page 1 organically. He's done some email marketing and part of his retention program is to have people book online so he's driving traffic organically and now he's #2 organically just under Yelp. He is also #1 in maps as well in his city. His city isn't incredibly competitive but small considerations and tweaks like those can make a big difference. We've done no other work besides the redesign so it just reinforces that site structure is incredibly important.
