Publisher Guide: Comparisons

Meta vs Google for lead gen affiliates

This guide compares Meta (Facebook and Instagram) and Google as traffic sources for MVA and home improvement lead offers. By the end you will be able to decide which source to start with for a given offer, set up a fair side-by-side test, and judge the result on sold leads rather than clicks.

Both are approved traffic sources for Summit publishers, and both send traffic to Summit landers through your tracking link. The difference is how people arrive: on Google they are searching, and on Meta they are scrolling.

The core difference: demand capture vs demand creation

Google Search shows your ad to someone who just typed a query, such as a search for an accident lawyer or a roof replacement quote. The person already has the need, so your job is to match the query and make the next step clear. Google describes how keywords in Search campaigns decide when ads can show.

Meta shows your ad to people based on who they are and how they use the apps, not what they searched. Many of them have the need but have not acted on it yet. Your ad has to name their situation clearly enough that the right people stop scrolling. On Meta, the copy does the qualifying that a keyword does on Google.

Side-by-side comparison

How Meta and Google compare for lead gen affiliates
Factor	Meta	Google
How people arrive	Scrolling a feed, not looking for help yet	Searching for help right now
What qualifies the click	The ad copy and image	The keyword and match type, then the ad
Targeting controls	Location, age and broad audiences; the delivery system finds people	Keywords, negative keywords, location and schedule
Creative work	Images and video, refreshed often as ads tire	Short text ads, with landing relevance mattering most
Volume ceiling	Set mostly by budget and creative	Set by how many people search in your states
Main policy risks	Implying knowledge of personal attributes such as health, sensational images	Misrepresentation, legal and local rules, keyword insertion creating claims
Reading results	Results vary by ad; test creative first	Results vary by keyword; test search terms first
Learning curve	Faster to launch, harder to keep fresh	Slower to build, steadier once tuned

Policy details are in Meta's Advertising Standards, including its rule on privacy violations and personal attributes, and in Google's Google Ads policies, including misrepresentation.

Which fits each vertical

MVA offers

Search for accident help exists in every state, and the people searching are close to acting. That makes Google a strong source for MVA, but legal search terms are competitive, so keyword choice and negative keywords decide whether a campaign works. Meta reaches people after a crash who have not searched yet. It can produce more volume, but only if the copy names the accident and the time frame. See how to run MVA traffic on Google Ads and how to run MVA traffic on Meta.

Home improvement offers

Homeowners search when a project is close, for example after a leak or before selling. Google catches that moment. Meta works well for projects people put off, such as an old bathroom or drafty windows, where an ad can prompt a decision. Visual categories like bathroom remodeling and flooring tend to suit Meta creative. See how to run home improvement traffic on Google Ads and how to run home improvement traffic on Meta.

How to test Meta and Google side by side

01
Step 1: Pick one offer and one state group
Use the same offer and the same states on both sources. If Meta runs car accident in one region and Google runs truck accident in another, the comparison tells you nothing.
02
Step 2: Give each source its own sub IDs
Use a sub ID prefix per source, for example "m-" for Meta and "g-" for Google, then add campaign and ad level codes. Leads are reported by tracking link, so this is how you will separate results. See tracking links and sub IDs explained.
03
Step 3: Build each campaign the way the source works best
Do not copy one structure into the other. On Google, start with a tight set of keywords and a negative keyword list. On Meta, start with broad audiences and three to five ads with different angles.
04
Step 4: Match the message to the same lander
Both sources should promise the same next step, because both lead to the same Summit lander. Different promises produce different lead quality, which muddies the test.
05
Step 5: Set equal test budgets and a fixed window
Decide before launch how long the test runs and how much each source gets. Do not move budget between them until the window ends.
06
Step 6: Compare on sold leads and returns
You are paid rev share on sold leads, and unsold leads are not paid. Compare the sources on how many leads sold, what they sold for in your reports, and how many were returned, against what you spent.
07
Step 7: Decide and keep testing
Move most budget to the stronger source for that offer and state group, and keep a smaller test running on the other. Results can change with season and buyer demand.

Running both at the same time

Once each source works on its own, many affiliates run both. The two sources reach people at different moments, so they can cover more of the same market without simply competing for the same clicks. A few habits keep the combined setup readable:

Keep the sub ID prefixes. Every lead should still show which source it came from. Do not merge sources into one sub ID to save time.
Watch for overlap. A person may see your Meta ad and later search on Google. Each lead is reported once, by the tracking link it came through, so do not expect two sources to share credit.
Stagger changes. Change one source at a time. If you raise Meta budget and add Google keywords in the same week, you will not know which change moved your sold leads.
Plan states together. If one source does better in some states, shift that source there and let the other cover the rest. The geo-targeting by state guide covers how to split states.
Scale the stronger source carefully. Follow how to scale a winning lead gen campaign rather than raising budget on both sources at once.

Before you choose: a quick checklist

Do you have the creative capacity to refresh Meta ads often? If not, start with Google.
Do you have experience with keyword lists and negatives? If not, expect a longer build on Google.
Have you read the policy pages for the source you pick?
Is your sub ID plan ready so each source reports separately?
Do both campaigns send traffic to your tracking link, not to a copy of the lander?
Have you set the test window and budget before launch?

Common mistakes

Comparing different offers. A test only works with the same offer, states and window.
Judging Meta on its first ads. Meta results depend heavily on creative. Test several angles before you decide.
Judging Google without negatives. Without negative keywords, legal and home searches pull in job seekers, DIY questions and other unrelated clicks.
Using Meta instant forms. The lead has to submit on the Summit lander, where consent is captured and recorded.
Picking the winner on lead count. The source with more leads is not always the one with more sold leads.

Frequently asked questions

Is Meta or Google better for MVA leads?

Neither wins for every affiliate. Google catches people who are already searching, and Meta reaches people who have not searched yet. Test both on the same offer and states and compare sold leads and returns.

Can I run the same ad copy on both?

The message can be the same, but the format cannot. Google ads are short and tied to keywords. Meta ads need an image or video and copy that qualifies the reader. Write for each source.

Do I need separate tracking links for Meta and Google?

Use sub IDs to separate them at minimum. Ask during onboarding whether separate tracking links per source suit your account.

How long should a Meta vs Google test run?

Long enough for both sources to produce leads that have had time to sell or be returned. Set the window before launch and do not end the test early because one source looks ahead in the first few days.

Which policies cause the most rejections?

On Meta, copy that implies knowledge of the reader's health or situation. On Google, misrepresentation and claims that break local rules. Read Meta ad policies for lead gen affiliates and Google Ads policies for legal and home services traffic.
