URL Structure:

The actual structure of your website URL can have an impact on the search engines ability to index and understand your website content. Opting for a more organised URL structure will have the greatest impact.

Pictures:

There is nothing worse than landing on a webpage and being faced with mountains of text. Not only are pictures a great way to break up sections of text, but they also serve as an opportunity to communicate with the search engines. Because search engines cannot tell what a picture is by scanning it, they look for clues in two places.

Every picture you upload to your website will have a file name. When the picture is inserted on your website, the picture’s file name actually lives in your website’s sources code, or HTML. Since the search engines scan your website’s code, you should use file names that describe the picture. For example, ”red-tennis-shoes-veIcro.jpg” is much more useful than ”pic12345.jpg”

Additionally, you can give the search engines an extra hand by including alt tags on all pictures on your website. Alt tags are short snippets of code that allow you to tag each photo on your site with a short text blurb.

Title & Meta Tage:

Besides an actual text headline on your page, every webpage you create has a title tag. This is the text snippet that appears in the upper left corner or on the tabs of your web browser. Also, the title tag is the blue link that the search engines show when they list your webpage on the SERP. Title tags max out at 60 characters, so choose your words wisely.

Meta tags are snippets of code you can include within your webpage’s HTML. The meta tags are usually located near the title tag code in the head of your HTML. There are two meta tags meta description and meta keywords.

The Meta description is a text snippet that describes what your specific webpage is about. Meta descriptions are usually the first place a search engine will look to find text to put under your blue link when they list your website on the SERP. If you do not have a Meta description, the search engines will usually select a random piece of content from the page they are linking to. The Meta description is limited to 150 characters.

Meta keywords consist of an additional text snippet in the HTML that allows you to list a few different keywords that relate to your webpage. Back in the day, search engines used this field to determine what keywords to rank your webpage for. Now, most search engines claim they do not even use meta keywords when indexing content. Some small or niche search engines may still use it though. As a best Practice, it is recommended to put 5-7 keywords in the meta keywords, but don’t spend too much time thinking about it.

Headline Tags:

When the search engine bots scan your webpage's, they look for clues to determine exactly what your webpage is about. Keywords that are treated differently than most others on the page show the search engines that they are more important than other keywords on the page. This is why the use of headline tags within your page is so important. By using various headline tags (each tag will produce a different size headline), you not only make your webpage easier to digest from a reader’s standpoint, but you will also give the search

Engines definitive clues as to what is important on the page.
