How much should I invest in online advertising as a percentage of my advertising budget?

Question is how much you would like to pay for a lead/customer/subscriber etc ? And how many of them can your sales team / production team can handle.
once you get that equation right, scale as much as you want.
Additionally spare 10 to 20 percent of whatever you are spending on experimenting with new acquisition channels so you can always optimise and improve the equation.

It will depend on who is your target audience & what is the product you are selling.  If your target consumer are more inclined on doing things online then invest in online ad (perhaps 40% of it) but you should be careful in choosing the right partner to do the ad for you.  The partner should be dealing with the age group you want.  then the rest of the advertising budget you may go for static ads but with high eye traffics and more relatable selling points for your target group.

It all depends the area of Business, Price, Products and intended market. First thing would be to have brainstorming meeting with your think tanks in your organization who are specialist in this field eg. Marketing team, PR, Sales etc. To get primary hand info on the situation.

Depends on your total budget, target audience, campaign objectives and what other alternative channels such as radio, TV ...etc

Thanks for the invite,

You can investpercent on your online budget if thats befitting your marcom and sales model.

However, realistically, I would recommend you to extract the approximate CPA (cost per acquisition) of your customers online, and make it x3 folds to what your sales and retention team are capable of handling.

Of the total marketing budget? I could say...... but it all depends on your business nature and sales channels associated with it largely.

Hope it answers your question.

Best of luck.

this really all depends on your campaign call to action

That always depends on the product/service scale amount your providing to your consumers, hence you should always take some off your budget out funnel a digital advert channel.

 

Larger scale producing companies usually output a larger budget , company such as pepsi and coke. 

 

Sme's would usually start out funnelling adverts on facebook , other channels such as google ads may be effective to optimise your budget
