Perform monthly site-wide content checks. Increase the site's search-engine optimization. Add and improve web content.
In the rush of creating and posting the website, it's possible that some live content contains errors or is improperly coded. Fix any errors that you spot, including relatively minor issues: missing or incorrect punctuation, typos within copy, or spelling errors. Larger errors include: improper formatting, unreadable content, misspelling the company name, etc. If your company has a copy editor on staff, ask them to read through each of the website's pages and let you know about any grammatical or mechanical errors. Search-engine optimization (SEO) will help ensure that your website shows up on the first page of search-engine results when users search for terms similar to those your site uses. You can increase your site's SEO by including keywords related to your business or products in website copy. Also increase your website's SEO by ensuring that the site is easily navigable and efficient. Make sure that no pages display a "404" error. A quick rule of thumb is that a website with around 2,500 words total will perform well in Google searches. Depending on the nature of your website, it may contain a wide variety of types of content. Regardless, it's important to keep content up-to-date, or users will find your website dull and useless. Over time, you can also go through and improve web content: things like page layout, navigation bars, and links to social media pages should all be apparent and user-friendly. For example, if you're managing a commercial website which sells a product to consumers, you'll need to update the website with details about new products, new promotions or sales, or any recalls for faulty products. If your website isn't commercial, but provides news or blog-like opinion pieces, you'll need to regularly update content. Add new articles or opinion posts at least weekly, so that users don't become bored with the site.
