Google spiders

How far do Google spiders go down a page

i heard it was 250 lines

is this correct

I haven't heard of a finite line number which it will crawl until, or any precise information supplied by Google about this.

I do, however, know they have stated to try to keep pages under 90k and less than 100 links per page.

It was 100 Kb but I have seen bigger cached files than that.

Also google says keep links below 100 per page.

Welcome to SEO chat. Google spiders down a page according to these factors:

a. Crawlability of your page, is your page crawable? If your site is filled with text content, it is not problem.

b. File size- although now, GOogle can crawl big web pages but it is best to be conservative with it if possible for faster downloading. 100kb is used for some sites.

c. Number of links on the page- technically Google advised 100, though it can still crawl beyond that amount but for me 100 links per page is enough for both visitor visibility of those links and to help bots crawl those links quicker.

d. Robots.txt or meta robots exclusion- if the page is block , Google will not dare to crawl those pages.

thanks someone told me it was 250 lines before

the reason why i ask is that when i opened the source code for any page of the site i was about to optimize (older cold fusions site)

i found that in every page at least the first 15 to 20 lines were blank with nothing and also half way down the page at around 150 lines again there is a huge white space with no code all the way down to about 3000 lines

every page is like this

will all this blank white space affect the way it is spidered and indexed?
