WebSEO: Best quality Images and Videos
Here at WebSEO we select and use the best quality SEO images and video to boost your page rank to the top of the Google search, resulting in increase in your traffic.
How does it work
Here are some Do’s and Dont’s for Image and Video Captioning according to MOZ’s blog,
Google can segment text near an image to attribute that text to the image and even create its own captions; therefore, text near an image can help provide context and could affect rankings. Image captioning also provides context for screen readers, often providing more context than an alt attribute might, or in place of an alt attribute if one is not known at the time of upload.
Image captioning do’s and don’ts:
– Don’t use alt attribute if there is an image caption. Similar to the anchor text link, describing an image via alt attributes and a caption can be repetitive. This could also be a debatable practice, as SEOs would likely want to use both. In that case, consider how it will read by a screen reader that reads both a caption and an alt attribute, and try to make the best decision that will work for both
– Do describe what you’re captioning. For example, use “Figure 1:” so that this captioning tag is properly understood by people using assistive technologies that may not recognize the tag.
– Optional: Do use a figcaption tag: figure with figcaption tags can be applied to images or other page elements. Figcaption isn’t necessarily a known tag to optimize for SEO and they aren’t a must-do for screen readers, but it sounds like Google does try to index the text within a tag whether it recognizes the tag or not, and despite figcaption’s variable readability by screen readers, the text may be considered as a related element to an image for screen readers and hopefully helpful nonetheless.
Video transcription, subtitling, and captioning
Video transcription is the text of the video provided alongside the video. Video transcription is helpful to hearing-impaired visitors who can’t hear the video, or to interpret words for people watching something in another language or strong accents. It’s also helpful to anyone watching a video with sound that’s tough to hear, when watching video in a loud room, or when you need to watch with no sound.
Similarly for search engines, video transcripts describe the content of a video via text.
Video subtitling and captioning
Subtitles and captioning provide time-synced text along with a video while it plays. Subtitles provide the dialogue, while captioning provides the dialogue and also describes other sounds like music, sound effects and speaker identification.
Video accessibility do’s and don’ts:
– Do provide video (and/or audio) transcripts. The time and effort it takes to provide text alternatives can help search engines and various viewers needing a text accompaniment to understand the content.
Do upload or correct YouTube transcripts & captions: YouTube’s automated transcripts are convenient but usually weird and wrong, and therefore need to be edited for correctness. Having the correct text is helpful for your transcript-dependent viewers and, when search engines do index the transcript text, that text content can help surface the video page in search results.
– Do provide context. When it makes sense (especially in closed captioning), indicate speaker names, and other sound context like music, relevant sounds, laughing, cheering, shouting, crying, etc.
– Don’t spam. Don’t use transcripts for keyword stuffing. It’s a terrible user experience, and depending on your platform, a transcript may not be indexed by search engines anyway, so keep it real.
