With Google Panda algorithm thoroughly searches the internet to find pages that don’t match to its quality standards and penalizes websites with substandard content. Because of this, many websites become the victim with their old contents that back then weren’t optimized with SEO. Panda algorithm is one of the main Google algorithms, and its updating quite regularly. There’s an opinion that said content that have been around quite long time doesn’t matter, with assumption that Google with its Panda algorithm knows that older content is usually ignored by readers and is may not still relevant.
But the assumption is not true, because old, low quality content can hurt website search ranking, as long as it still on the website and can be found with search engine. Around 6 years or more, it was acceptable to post short blog posts, with 500 words or less, using any keyword-focused topic that hopefully bought many visitor. Back then, those posts was valuable, but not today, because a 500-word post is not enough, and a 1.000-word post is barely made it. According to a research from Medium, said that a post that takes about 7 minutes to read is has 1.600-word long. Another study done by SerpIQ revealed that the content of the top 10 search results from many queries have total words in a post that close to 2.400-words.
When you found old content that doesn’t match with recent quality standards, there are few things that you can do about it.
It’s acceptable to delete old content. Because this action could improve your website’s search ranking. For old content to get rid, to rewrite, redirect and merger similar posts can help to gain more traffic and more importantly Google will have a better impression to overall average quality of the site.
