Do google serps change when cache changes?

Trying to avoid "the filter"

[Mr_Roberto]

I have a site that is apparently "filtered" for its main highly-competitive commercial keyword - we are not in the serps for this keyword at all! (Its frustrating that google feels hundreds of spam-ridden affiliate and porn sites are more relevant than an exactly-on-topic original content site.) We do show up for searches of unique text that is on the site, so we don't think its a penalty (no seo spamming techniques have ever been used on the site).

We recently made major changes to the site, and the google cache is finally showing the new version. We're still not in the results though. Should the google serps reflect the new version of the site immediately? Or is there a delay between update of cache and change of serps?

How do yu know if you've been hit by a filter?

I have a site I did for my sister and google has 259 pages indexed but she is only getting 8 visitors a day. How is this possible?!

[Mr_Roberto]

Visitors depends on your ranking in the actual search results for the keywords that are relevant to your site. If the site isn't penalized for misdeeds, and you don't show up at all for your main keywords, you've probably been caught by a filter which has misidentified your site as spam (seems to be a common occurance lately).

But how to know for sure it s a filter or an algo change:)

Or is there a delay between update of cache and change of serps?

There is a delay until the next reindex. Perhaps someone else has identified a cycle between reindexes.
