TRAFFIC Figure 1: HTML5 link rel attributes worth considering, especially if you have a good idea of users’ general path through your site (see Figure 1). Image optimisation Images play a huge role in the speed of a web page, something which is both a ranking factor and a determinant of a user’s experience on your site. Engaging visual content adds a lot to the quality of content, but should never come at the expense of the search experience. Once you’ve selected images to use on your site, save them as either JPEGs or PNGs, with relevant filenames (both descriptive and including targeted keywords) and scale them to the size that they’ll be needed. Often - if images are not minimised to the size in which they’re needed – pages are slowed down as large image files unnecessarily load. You can further streamline images by reducing their file size with tools such as JPEGmini. Compressing images has no effect on their quality, but can have significant results in terms of load speeds. When adding the images to pages, also make sure that a descriptive alt. text (again including keywords) is added to them to help users who for whatever reason can’t see the image, as well as to aid search engines’ understanding of your content. When pages are still in draft stage, test them using Google’s PageSpeed Insights. This will give pages an overall speed score, and flag up any elements which could be hindering page speed. Another option is the YSlow chrome extension, which gives pages a grade based on overall performance symbols. They vary in size due to the complexity of the vector paths making up each glyph, and the number of glyphs used by the font. When selecting a font, consider its aesthetic values, and weigh these against their file size. It’s also worth considering whether the font works in other languages in order to retain a consistent “look” on international sites, and that certain web font formats are only supported by certain browsers. This can prove a costly mistake if you come to create market specific versions of a successful piece of content, only to have to go back to build phase to accommodate a font that works in the target market. If it’s necessary to serve different formats to different users in order to give all a good experience, this can mean a re-design. Whilst of course they’re all different, fonts contain some broadly similar information, so can be compressed in the same way that images can. Some are auto-compressed, and for those that aren’t, using GZIP can significantly reduce file sizes. There can be an advantage in using more common fonts such as Typekit or Google Fonts, as these are more likely to have already been cached by your site visitor. Our final tip in our experience as an agency that works on multiple content projects for operators and affiliates alike, is to include a speed checklist into your project briefing process. Be sure to discuss technologies, use of images, font selection and any internationalisation of the piece prior to going into production. Not only will your content efforts complement your SEO and site performance goals, but this can contribute to the smooth and profitable running of content marketing projects on a per item basis. Fonts and styles You should also consider the fonts you use when optimising your content for performance. Think about how many typefaces, weights and styles are necessary before adding them, as each will result in an added request to the server, meaning a slower overall page-load time.
