Link text is the visible text inside a link. This text tells users and Google something about the page you're linking to. Links on your page may be internal—pointing to other pages on your site—or external—leading to content on other sites. In either of these cases, the better your anchor text is, the easier it is for users to navigate and for Google to understand what the page you're linking to is about.
Additionally, the title must also be interesting enough that people will actually want to click on it! A good example of this would be PT from PTMoney.com, who wrote a great post about "making extra money." However, rather than a boring title, like "Make Extra Money," he titled it "52 Ways to Make Extra Money." Now that is something I would want to read.
Longer content not only helps in adding more keywords to it, but there is also a natural emphasis on information. The authenticity of a post increases with longer text, which means that Google would recognize it as something more relevant than a shorter and concise text. As search patterns are synonymous with long tail keywords nowadays, a longer text also improves the chances of your article/website to be on a higher ranking than others.
This is a great list of SEO tips. One tip you can add to your broken links section is that there is a free tool called Xenu Link Sleuth. It will automatically crawl your website (or a competitor’s site) and find all the broken backlinks (and lots of other things). It’s very helpful if you have a large site or need to find broken links you aren’t aware of. (like images and .pdf files)
An anchor hyperlink is a link bound to a portion of a document—generally text, though not necessarily. For instance, it may also be a hot area in an image (image map in HTML), a designated, often irregular part of an image. One way to define it is by a list of coordinates that indicate its boundaries. For example, a political map of Africa may have each country hyperlinked to further information about that country. A separate invisible hot area interface allows for swapping skins or labels within the linked hot areas without repetitive embedding of links in the various skin elements.
