The short answer
The best lead is the one already looking for you. Ranked for most contractors it goes word of mouth, then Google search and the map, then Google Ads, then the lead resellers like Angi, then social. Here is why each one lands where it does.
Not all leads are equal. A person typing your service into Google right now is worth far more than a name you bought or someone who saw your logo while scrolling. Once you rank the sources by how ready the person is to hire, the pecking order below sorts itself out.
1. Word of mouth, the gold standard
Nothing beats a referral. The trust is already there and the close rate is high. The catch is you cannot turn it up when work is slow, and you do not control it. Everything else on this list is really about manufacturing more of this.
2. Google search and the map, local SEO
The closest thing to scalable word of mouth. Someone typing roof repair near me has the same intent as a referral, they need the service now. You earn the top spots once and they keep sending calls, and the cost per lead drops the longer you rank. You own the asset instead of renting it. For most trades this is the best long term source there is.
3. Google Ads
Same high intent as search, and it turns on instantly, which is its big advantage. The downside is you rent it. The calls stop the day you stop paying, and the cost per click tends to climb. Great to run alongside SEO, especially early before your rankings build, but a rough foundation to stand on by itself. More on that in our SEO vs paid ads guide.
4. Angi, HomeAdvisor, Thumbtack
The lead resellers sell the same lead to several contractors at once, so you are price shopped against three other guys before you even call back. You do not own the customer and you compete on speed and discount. Fine as filler when you have gaps in the schedule, painful and expensive as your main source.
5. Facebook and Instagram
Cheap reach, but low intent. These people were scrolling, not searching for a contractor. Social is good for showing off finished work, building your brand, and collecting reviews. As a direct source of booked jobs for most trades it is weak.
Intent is the whole game
One person searching emergency plumber near me is worth ten who saw your ad between two reels. Sort every source by how ready the person is to hire, and the order above is what you get. That is why we build everything around the sources where people are actively looking for you.
What most contractors land on
Own your Google presence with local SEO as the base, add Ads to fill gaps and cover you while your rankings build, let referrals compound on top, and keep the lead resellers to a minimum. That mix leans on the high intent sources and stops you renting leads forever.
Common questions
Are Angi and HomeAdvisor leads worth it?
They can fill a slow week, but the lead is sold to several contractors and you compete on price. Build your own Google presence and you stop paying over and over for leads someone else also owns.
Should I start with SEO or Ads?
If you need calls this week, Ads. If you want the cheapest calls a year from now, SEO. Most contractors run Ads early and lean on SEO as it takes over. We compare the two in depth in our SEO vs paid ads guide.
What about Facebook or Instagram ads?
Good for brand and reviews, weak for booked jobs, because the audience was not looking for you. Useful as a supporting player, not something to expect to replace search.
Which source is cheapest over time?
Local SEO, because it compounds. Ads and the resellers cost the same or more every year. SEO costs less per lead the longer you rank, since you built the asset once and it keeps working.
