How does "good content" improve SEO?

I'll quote small sections of that long comment.

Your Meta description tag can be as long as you want it to be because Google will pull out the relevant parts of it and make their own snippet anyway.

Exactly!

That's why I think it's better to not include a meta-description tag. Instead of trying to force the description you think is correct for the best search traffic on the Google bot, let the Google bot pick the most relevant snippet of text on your page & display that snippet as the SERP description.

Everyone in IM knows Wikipedia ranks for a huge amount of keywords, the reason they rank is because they know on-page SEO. They know how to structure a site, they know meta-description & meta-keywords is old school SEO, today in 2012 those two tags are useless in SEO. IMO the meta-description tag holds you back from better SERP descriptions, that will get a higher CTR from organic traffic.

These days, Google often uses the first few words from your Meta description tag when they create the "extended sitelinks" for your website. But this too is not set in stone and is highly keyword dependent. You'll see different sitelinks and different descriptions showing up depending on the words a searcher used at Google.

Not true.

Google Sitelinks are from anchor-text links on-page, not just random on-page text. You can indeed highly influence which Google Sitelinks (anchor-text) are displayed in the SERPs. It's based on keyword relevance, anchor-text, & page authority of the internal page the anchor-text is pointing at.

Overall, the Meta description tag gives you a little bit more control over what people might see before they click over to your site. The more compelling it is, the more clickthroughs you should see. If your Meta description tags can help with that, then it's certainly worth the few minutes of time it takes to create interesting, keyword-rich tags that sum up what users will find when they arrive.

Again, you have know idea what the exact keyword or keyword sequence will be when someone is searching for a keyword on Google. Let Google pick the SERP description & you'll improve the relevance of what was being searched for, which in turn will help with a higher CTR. I'm not just blowing smoke here, I've been testing this for a while now (not reading ebooks or blogs (actual testing on my own sites)) & the meta-description tag is a dinasour. I understand folks don't like to let go of things when it comes to SEO, seriously that ship has sailed.

Good content that is key word focused and that has key word focused links pointing back to it is better for SEO than just having good content....
