You bet, how about every quarter. Sometimes when you're in the ditch you can't wait 6 months.

I keep an eye on marketing plan all year long.

Sometimes I adjust mid month.

Not really. -Kasey

It is smart to constantly improve your plan.

Will, I make adjustments quarterly because that is controllable an a half year or year is too long of a period to let changes go without happening.

Generally not, but this year we have some changes coming in June.

As needed throughout the year.

I look at ROI quarterly and make adjustments.

if the market changes, my marketing needs to be altered.... I make adjustments.... the way I market works....I would either increase it or decrease it.... that reflects the state of the market....

Like, Joe Pryor, I make them quarterly and then a big adjustment at the end of the year!

If need be..certainly! I actually review every quarter and make adjustments if necessary.

Only when needed, but I don't wait for a specific day to determine it.  It's an ongoing determination.

Never, i adjust it when needed. Monthly, semi yearly , yearly or when i see a need

My hubby does this for me. We tweak each month and do a more detailed analysis each quarter.

The plan is the plan unless it's revealed somethings off, we review the plan monthly, but it's a pretty proven plan after 18 years of practicing it.

Staying the course.

Always refining rarely redefining.  

I adjust when ever needed.

Slow and steady as she goes here Will.  

If need be

only minor adjustments

We look at our marketing more frequently...sales figures compared monthly to last year and projected for the current year...what are we doing or not...to us, six months is too  long for a review.

YEs; I plan to go more vegetarian when grocery shopping for the second half of the year.

Yes.

I watch my plan & results monthly & make adjustments whenever deemed necessary.  :)

I have no plans, so no I don't. I am in auto-pilot on what I do each year.

Will,

Keep spending on what works, and stop doing what does not work. A

Will Hamm - yes, need to adjust for sure.

If I need to I would but as of now I am staying the course.

Just send money...

yes. . .  I see what is working and what is not. . .  then try new advertising, new marketing, emails, etc to see where I get the best response.  Real estate is constantly changing. . .  keep up with the buyers and sellers needs

Prefer quarterly, but as Lyn Sims said when you are in a ditch, it's time then and there!

I adjust it constantly with every new transaction. At this moment, i'm working very hard, I hope, it all will pay off.
