I'm aware that excessive javascript lowers rankings, but is there any benchmark as to how much is allowed?
How can you be aware of something that isn't true? Excessive javascript does not lower rankings. There is a limit to how much content gets indexed, but the presence of javascript doesn't lead to lower positioning EDIT: As per a sitepoint experiment, Yahoo indexes 210KB of data, Google indexes 520KB and MSN indexes a staggering 1020GB of data on each page. As long as your page size is less than 210KB, then the big 3 search engines will index all the content (other crawling/indexing issues aside).
Thanks. Good to know!! Could it damage a kw ranking slightly if the bot picked up the javascript before some crucial content? Sort of the same way too many tables get in the way? 1020GB is staggering!!! ++)
There was a mistake, we are actually talking about MSN indexing 1020 KB, not GB, see above for correction. Regards
Not unless content position in your page matters, and I believe it doesn't. There's another thread going that discusses that very issue: http://forums.digitalpoint.com/showthread.php?t=216244
