Test your links.
Make sure your site works! Load your site in a browser from the Internet (not from your hard disk), make sure all the images appear correctly, and click on all the links. This may seem obvious, but if it’s so obvious, then why do I constantly find sites whose images and internal links don’t work right? If you’re using a link checker that’s built in to your web editor and your site is framed, then you can’t depend on the link checker, because it can’t check for framing problems (e.g., pages load into wrong frames, clicking a link results in frames within a frame, etc.). Check it yourself.
Remove dead external links periodically.
If you link to any external sites, some of those links will almost certainly stop working at some point as the sites move or become extinct. Don’t waste your readers’ time by forcing them to follow broken links. Check your links at least once every few months. You can use software to automatically check your links to external sites to see if any of them have gone dead.
Include a “Last Modified” date on the top or bottom of your pages.
If your site contains information that could become outdated, then do your visitors the courtesy of letting them know when the information they’re reading was written. That way, visitors won’t have to wonder whether the info was written last week or five years ago.If your content by its very nature can’t become outdated. (e.g., poetry, stories, art, website design tips), then a date isn’t absolutely essential,, but readers may still appreciate knowing when a page was authored
