Does multiple topics cause problems?

[Jeremy_H]

I've been building up my website about widgets for a while, and I've been very pleased with the success of my AdSense account.

I started another website about something completely different, hoping to diversify my ad base.

But ever since I launced this second site, I'm noticing a drop in earnings per thousand & earnings per day.

Do you think these two things are related?

It is believed by at least several people here that one site can affect adsense revenues on another site of the same account.

There was yesterday a thread, which disappeared today.

As far as it seems from my view point

Somebody created by a strange trick a maximal smart pricing deprecation for his site.

He put his code on a good runing AdSense site from somebody else.
The created bad smart pricing situation on his own site was also on the other site.

My own main income is one domain with several thematic different sub domains. Works great!

So You have only to see, that each topic has a good quality.

How big is the drop? Remember that with adsense, large peaks and troughs are perfectly normal. We see loads of "My income has dropped" thread here, and there are always people for whom it has risen to balance this out. Swings and roundabouts.

It may be that what you are seeing has little to do with the new site, but is just a normal unexplained blip/dip.

I guess the way to test it would be to remove the ads from the new site and see what the change is. I did a bit of experimenting recently to see what effect altering pages on the rest of the site had on my main banner, and found that there was no obvious trend.

I'd certainly be using a channel for each banner, and be analysing the results closely. I'd also be removing banners that don't work.

I would really like to know the final answer to this question. I am about to launch some new web sites. Since I think that ads in the same domain are heavily tied to the "main argument" of the original web site, I considered using a third level domain to try to avoid this, but I'm afraid that ads will still be "grouped" according to the second level domain.
This sort of "grouping" can be really useful when you have 10 pages where it is clear what you are talking about and, say, an 11th page where you offer something that is obviously related to the previous ten pages, but where it is quite difficult to decipher the exact argument. The same "grouping" effect can, on the other side, bring totally unrelated ads on new pages on new subdomains and, what would be even worse, might end up modifying the original, hopefully perfectly targeted, ads.

With regards to targetting, I could not notice any problems with multiple topics.

I am writing about various topics but my focus is on widgets, and I expected to see this influence my other topics, that are completely non-widget. It's just at first that AS needs a bit of time to adjust the targetting, but after a while it's right on the spot.

As to the payouts, I cannot comment as I never bothered to use the channel feature (as most of the traffic and ads are widget related anyway).

Ah - but as soon as you are writing about different widgets, you enter a different market. Different advertisers are competing over different terms. Surely this can influence the whole Adsense behaviour.

after starting another new website 15 days before, my earnings and eCPM getting down , and also very little clicks in the new website ( related to film industry with daily updation ). I think , i should remove the adsense codes from the new website.

[jetteroheller]

Film industry?

After my experience, film sites have a very low CPM.

I had a film site with about 4000 visitors a month.
I did not renew the domain name.
Just covering hosting and domain name

[indias next no1]

yes , the CPM is low, but i am running the website for the visitors who are much interested with my fresh and unique content. But after starting the second website 15 days before the earnings comes down. ( my both the websites are film related but with different concept and content )

Does multiple topics cause problems?

I have several sites that deal with multiple topics and they all do very well with AdSense.

I'm not worried for already established web sites, but for new ones, with not many pages, added to an AdSense account where there is already a well established other one.
