In an online Q&A session, Google's Matt Cutts answered the questions of webmasters who want to get higher rankings on Google for their websites. This article summarizes the most important SEO relevant statements of this session.
The effect of +1 clicks on your organic rankings and ads
Google is still testing the effect of +1 clicks on the search results. It seems that only clicks from trustworthy people will influence the position of a web page. In other words, it won't help to buy +1 clicks.
In addition, the +1 clicks on ads will show others who have +1′d it but that is all at this time.
You cannot exclude keywords from your website
It's not possible to ensure that your website does not appear in the search results for a particular keyword. The reason for that is because that could be a way you could silence critics or not show up for negative reviews.
The age of a website is important but only one of many factors
The age of link anchors and domains can influence the position of a website in the search results. However, Matt Cutts says that you still need fresh information because old information can get stale.
Google decides per keyword if the search results show websites with newer or older content. Old websites often tend to have more links and that the links are often the reason why older domains have higher rankings.
Google will rewrite your meta description tag
Google will only use the meta description of a web page if they find it appropriate to the searched keyword. Google will also write its own description to show the searcher why the page was ranked for the query.
What to do if other websites steal your content
You should do a DMCA complain and a spam report, especially if the other website is a spammer who is scraping content completely.
Double 301 redirects are okay
A web page shouldn't redirect to more than 4 URLs. Chained 301 redirects should be only 301 redirects and they should not be mixed with 302 redirects.
Google uses many different factors to determine the position of a web page in the search results. Analyze your web pages with IBP's Top 10 Optimizer to find out how to adjust your web pages so that they get listed on Google's first result page for your keywords.
