Metatags -Metatags are units of information used to define electronic web pages according to various properties such as author, keywords, and description. Metatags are embedded into the source of HTML pages, PDFs, JPEGs and other formats. Without the proper metatags inserted into the code, people cannot easily find the information or data on your site via search properties, features or engines. Keywords, Author and Description Metatags are important attributes of the HTML tag because documents containing these metatags can easily be searched among the millions of pages on the Web. Missing Titles -Missing titles are electronic pages that lack titles at the top of the page so visitors can't quickly grasp the concept or the content of the document.
Titles are useful for bookmarking pages.
Titles are programmed into the HTML at the top of the page in greater than and less than brackets. Missing Attributes -Missing attributes affect the download time and without them the browser doesn't know what's loading and therefore doesn't leave spaces for images, this ultimately slows the download time. Height and Width Tags define the images so the browser will know where to leave space for them while uploading the entire page - text, images and graphics. Links are encoded in web pages using tags. Broken Links -A broken link, when clicked on, takes you to an error page.
