How much is too much?

So yea, I have been working on this SEO tool.. which would edit the meta tags, description and keywords to match the page you are on..

so if you are reading a thread, it would pick up parts of it, and add it into the meta tags.

but, some threads are just huge, so it makes the meta description tag huge too.. the question is, how much is too much for a description / keywords tag?

thanks

 

I think 26 words is the reccomended by Google, I saw it somewhere

-G

 

thanks, so it would affect google if the desc meta is long? like 50 chars maybe...

 

if your asking youself this question then you already know the answer is yes its too much

 

i know that you should not have more then 9 words in the title

 

i think about 160 characters in description is fine,google only shows so much in SERP.
btw,description and tile are important to attract visitors.

 

I think Maximum 200 char should be taken in description tag and 20 key phrases in keyword tag.

 

cut down on those words

 

I also think keyword and description should not be more than 200.

 

Cut down the keywords that has less value, and use those keywords in your text.
