To help web developers maintain a common style, on April 25th Google published its own HTML and CSS Style Guide containing best practices to encourage better coding etiquette. Google’s HTML/CSS Style Guide promotes good style advice that is also good performance advice, making it a good standard to use.
Great code has many attributes. It’s effective, efficient, maintainable, elegant. When working on code with many developers and teams and maybe even companies, great code needs to also be consistent and easy to understand. For that purpose there are style guides. We use style guides for a lot of languages, and our newest public style guide is the Google HTML and CSS Style Guide. via Official Google Webmaster Central Blog: Coding guidelines for HTML and CSS.
In 2009 Google removed the PageRank that used to be stated in our webmasters accounts and has downplayed the value of PageRank. This is because web masters became obsessive about attempting to game search engine results. Google also did a Toolbar PageRank Update yesterday. The last one was in February and these take place at roughly 3 month intervals ie. 4 updates annually, as Google’s Matt Cutts shares in the video below.
How do PageRank updates work?
PageRank calculation is Google’s way of deciding relative importance of a webpage. PageRank is a numeric value that represents how important a page is on the web. Google figures that when one page links to another page, it is effectively casting a vote for the other page. The more votes that are cast for a page, the more important the page must be. Also, the importance of the page that is casting the vote determines how important the vote itself is. Google calculates a page’s importance from the votes cast for it. How important each vote is is taken into account when a page’s PageRank is calculated. It matters because it is one of the factors that determines a page’s ranking in the search results. It isn’t the only factor that Google uses to rank pages, but it is an important one. Source: Google’s PageRank explained and how to make the most of it
These are the positive factors that Google’s algorithm takes into consideration:
1. Keyword Use In Title Tag
2. Global Link Popularity Of The Site
3. Anchor Text Of Incoming Links
4. Link Popularity Within The Site
5. Age Of The Site
These are the negative factors that Google’s algorithm takes into consideration:
1. Server Is Often Inaccessible To Googlebot
2. Content Which Is Very Similar Or Duplicate to Existing Content On The Web
3. External Links To Low Quality Sites
4. Participation In Link Schemes or Actively Selling Links
5. Duplicate Meta Tags On More Pages
If your site’s PageRank dropped in this last update, below is a video by Google’s Matt Cutts explaining why this may have happened:
How can I identify causes of a PageRank drop?
There are many factors that go into PageRank calculations. The most persuasive factor is backlinks to your posts, especially those from high authority blogs. Normally a blog does not achieve a PageRank until after 6 months have passed. This is referred to as being in Google’s sandbox and during this timeframe you have an opportunity to build search engine trust. Why is that necessary because the majority of all sites created every day are created by spammers and sploggers. Develop a site strategy that effectively addresses the positive and negative factors for determination of PageRank. Make it part of your blog strategy to focus your attention on the following:
- publishing high quality unique content frequently;
- creating clean code and ensuring your site validates;
- using keywords in your content naturally and tagging properly so the content can be found and indexed;
- linking to exceptional content on authoritative sites with PageRank;
- being careful not to link too link to frequently to sites with lower PageRank and/or to avoiding reciprocal link exchanges with unrealted sites.
*You shouldn’t link to any content unless it’s exceptional and related – this goes double when your site is new and in the 6 month Google sandbox. You earn Google’s trust by linking to authoritative sites with PageRank, and not to too many new sites.
