Remove Comment Tags - Keywords in comment tags could be construed as spam. So remove unnecessary comment tags from your source code. I came across a webpage that included multiple header tags and keywords in a comment tag. This is not recommended.
Another one had several hundred lines of HTML code hidden in a comment tag. Such code is not executed, so it’s simply a waste of space and download time. Make a backup of the page, and remove the unused code from the published webpage.
Alternative Text - Don’t use more than one ALT (alternative text) attributes in IMG (image) tags.
<IMG SRC=image.jpg ALT=”keywords, more keywords, blah…”
ALT=”keywords2, and more keywords, blah, blah…”>
In addition, only use one keyword phrase in ALT attributes. I came across ALT attributes that included almost 50 words, or over 300 characters.
Fix Broken Links - Check for broken links. Relative links are the most common culprits.
These links may work fine on your computer. But it doesn’t work when you upload it to a server.
