Fix the meta description. Phil Tadros, leader of coworking space Space Doejo, emphasized the importance of the meta description. “I went out of my way to spend time tweaking and fine-tuning the meta description of my site," Tadros said, "because this is one of the first things people see. It’s vital that you make a promise you can keep.” Your meta description is your first chance to encourage people to click on to your website. There are plenty of plugins allowing you to edit the meta description if you don’t have a custom-made platform. A meta description may not impact SEO directly the way it used to, but it enhances the user experience.
So, you have downloaded your links profiles on a CSV and you now have an extensive list of all your linked domains. If you have been doing SEO for 8+ years like me you can probably just know from analysis which links are bad from a TLD and URL point of view. If you do not know too much you can use tools such as Link Detox: http://www.linkdetox.com/ to complete analysis of your link profile. I would always consult the advice of an expert SEO in this instance because it is easy for these tools to mistake good and bad links.
Optimization techniques are highly tuned to the dominant search engines in the target market. The search engines' market shares vary from market to market, as does competition. In 2003, Danny Sullivan stated that Google represented about 75% of all searches. In markets outside the United States, Google's share is often larger, and Google remains the dominant search engine worldwide as of 2007. As of 2006, Google had an 85–90% market share in Germany. While there were hundreds of SEO firms in the US at that time, there were only about five in Germany. As of June 2008, the marketshare of Google in the UK was close to 90% according to Hitwise. That market share is achieved in a number of countries.
Facebook ads contain links back to your business’s page. Even if the goal of your ads is to get people to click on a link that takes them off of Facebook, there’s a chance they’ll go directly to your Facebook page to learn more about you. If your page is empty or outdated, that’s where their curiosity ends. If you’re spending the time and money to advertise on Facebook, make sure you follow through with an up-to-date Facebook page.
Well, yes and no. Sure, you can get hit with an algorithm change or penalty that destroys all your traffic. However, if you have good people who know what they are doing, this is not likely to happen, and if it does, it is easy (in most cases) to get your visits back. Panda and Penguin are another story, but if you get hit by those it is typically not accidental.
