Google’s Matt Cutts: No More PageRank Updates This Year

Google’s head of search spam, Matt Cutts, said on Twitter yesterday that Google won't be pushing out a new Google Toolbar PageRank update this year.

Matt Cutts said that he would be surprised if there will be any PR update before 2014.

It has now been 8 months since Google Toolbar PageRank updated. The last update was on February 4, 2013. Google never offered Toolbar for Chrome or any add-on to show PageRank values. Google dropped the Google Toolbar for Firefox in June 2011 and Internet Explorer is the last browser to still have a PageRank display features offered by Google, but the data that flows into that display has not been updated from more than six months.

Matt explain that Google’s own browser, Chrome does not have PageRank built into it. Plus, IE 10 does not allow add ons. So, he wouldn’t be surprised if the PageRank values in the toolbar go away by themselves. He said Google will continue to support it as long as users are using it.

Why aren't the Google Toolbar PageRank values updated more often?

How many links on a page should we have? Is there a limit?

Google’s Matt Cutts released a video explaining why Google no longer has that 100-links-per-page Webmaster Guideline. That guideline was dropped well before 2008, but webmasters still think having over 100 links on a page may lead to a penalty.

Google’s Matt Cutts – We Dropped The 100 Links Per Page Guideline but We May Take Action If It Is Too Spammy.

For example Sites like Techmeme likely has thousands of links on the home page, but they are not penalized by Google. 

Google said if a site looks spammy and has way too many links on a single page, Google reserves the right to take action on the site.

Matt also explained that your Page Rank is divided by the number of links on a page. So if page A links to page B, C and D that Page Rank is divided into three. If you have hundreds of links, it is divided by hundreds, and so forth.

Google+ Custom URL

Google+ Custom URL or vanity URL is short and simple web address that link to your Google profile or pages.

For example, instead of having complex URL which is difficult to remember like:

https://plus.google.com/108792510903002495904/

Now we can get custom URL, which is easy to remember and   Google+ URL :
