Adsense irrelevant ads

[Cornolio]

I use to have irrelevant adsense ads on my forums.
I thought about customizing keys and descriptions for every forum.

like this?
<if condition="$GLOBALS[forumid] == 3"><meta name="keywords" content="cinema, teatro, tv, televisione" />
<meta name="description" content="Forum su cinema teatro tv" />
<else />
<meta name="keywords" content="$vboptions[keywords]"/>
<meta name="description" content="$vboptions[description]"/>
</if>


otherwise, how to disable forum access only for adsensebot (so it only crawls meta tags)? this should help, 'cause i heard that someone disabled forum access for unsubscribed users (so even for bots) to have relevant ads ('cause bots crawls only keys and description)

Google adsense ads are based on what google sees.

Google sees more than just the meta data.

Google sees all.

i already know that. you didn't read what i wrote. you're not helpful.

And you still don't understand adsense...or spiders in general.

1. If you block access to your forums for adsense, you will receive nothing but ads about Password protection and the like.

2. If all the spiders can see is the same thing (whatever that might be) they aren't going to index you very well, due to seeing every page on your site as being duplicate content.

3. As per the Adsense Program Policies: "No Google ad may be placed on any non-content-based pages. This includes error, login, registration, "thank you" or welcome pages." To show spiders a non-content page would violate your adsense.

mh, i know i know. the point is that somone did it, and he got relevant ads...

however i wouldn't disable access to all spiders. only adsense bot

i'm going to customize meta tags. this should help

If the adsense bot can't spider anything, Adsense will not show anything - simple, heh?

I've got a question about adsense too.
I have placed adsense blocks in the Forum (navbar), as well as in the archive.
But I noticed that for the same thread I do get relevant ads in the archive, but not in the real thread.
Now as most users understandably don't use the archive that is not that good.
IMHO the problem is that the adsense bot sees too many irrelevant text (Navation Buttons, Menus, Usernames and so on) and thus gets irritated.

I though about creating a "ultra light" style that only shows the raw content (Board Titel, Forum Titel, Forum Description, Thread Title, Message Text), then detect the Adsense Bot and assign this style.
So the bot would only see the really relevant content, and it could reduce bandwidth usage.

Basically this would be moreless the same as the archive, but it would take the same setting (posts per page, date cutoff, etc.) as the real threads.

What do you think about this idea?
Would it violate the TOS for adsense?

adsense will display what it thinks is most relevant to the page...
and this depends on what adsense (spider) finds -- and, how frequently it finds it -- and, how much of your page it reads (eg, first 1000, 2000, 5000, 10000, etc characters)

so if your thread is about a particular topic but it displays something else I suggest that you make sure that your meta tags, title page, etc all use the title of the thread ... I also, recommend adding a small (100 - 200) characters of the forum description or thread message below navbar or somewhere above thread table

in this manner, when the adsense spiders come to crawl your page they will find more keywords relating to the topic of the page

the key here is to have as many keywords on the upper half of your site

DID YOU KNOW?
if you have a left-column ... the left-column content is crawled before anything anything else--so, if the adsense only crawls 2000 characters you may not get relevant ads

-----------
| | xx xxx |
| | xx xxx |
| | xx xxx |
| | xx xxx |
------------

I know :)
That's why I though about showing it only the really relevant stuff.

That could be a problem, as I got a pretty large sidebar ...

[Princeton]

you could rebuild the table so that the left-column is not the first thing it crawls

for example...
2 rows on left column (1st row empty - left-column content on second row)
1 row on right column (rowspan=2)

this way when the spider comes to crawl your page ... it will find the first cell (1st row) and find it empty ... it will then move to the next cell (right column) and crawl that before moving on to the left-column (2nd row) contents

This is a great idea!
Gonna try that out

why din't you read what i wrote???

btw how to detect adsense bot and "give" him a style?

[Andreas]

As far as I understood this you want to want to disable access for the adsense bot, right?

[Cornolio]

right. so he would be able to read only the meta tags (right?)

You dont. That would be considered cloaking and could get you banned from both adsense and the google serps. Google specifies that their bots should see the same page any other visitor sees.

There is alot of 'static' sometimes with vbulletin, and adsense, especially before it has learned about your site theme, will have a harder time returning good relevant results.

This might help. Try reading these articles:

Pay close attention to the sections about title and descriptions - and the part about h1 tags. Put your adsense banner below the h1 tags.
