If you're looking to upload an image to a blog post, for example, examine the file for its file size first. If it's anywhere in megabyte (MB) territory, even just 1 MB, it's a good idea to use an image compression tool to reduce the file size before uploading it to your blog. Sites like TinyPNG make it easy to compress images in bulk, while Google's very own Squoosh has been known to shrink image file sizes to microscopic levels.
The strength of your link profile isn’t solely determined by how many sites link back to you – it can also be affected by your internal linking structure. When creating and publishing content, be sure to keep an eye out for opportunities for internal links. This not only helps with SEO, but also results in a better, more useful experience for the user – the cornerstone of increasing traffic to your website.
In December 2009, Google announced it would be using the web search history of all its users in order to populate search results. On June 8, 2010 a new web indexing system called Google Caffeine was announced. Designed to allow users to find news results, forum posts and other content much sooner after publishing than before, Google caffeine was a change to the way Google updated its index in order to make things show up quicker on Google than before. According to Carrie Grimes, the software engineer who announced Caffeine for Google, "Caffeine provides 50 percent fresher results for web searches than our last index..." Google Instant, real-time-search, was introduced in late 2010 in an attempt to make search results more timely and relevant. Historically site administrators have spent months or even years optimizing a website to increase search rankings. With the growth in popularity of social media sites and blogs the leading engines made changes to their algorithms to allow fresh content to rank quickly within the search results.
On another note, we recently went through this same process with an entire site redesign. The executive team demanded we cut out over 75% of the pages on our site because they were useless to the visitor. It's been 60 days since the launch of the new site and I've been able to still increase rankings, long-tail keywords, and even organic traffic. It took a little bit of a "cowboy" mentality to get some simple things done (like using 301's instead of blocking the old content with robots.txt!). I predicted we would lose a lot of our long tail keywords...but we haven't....yet!
