Talking about website optimization will lead us to the topic of image optimization as it has an important role in seo. At this time I try to discuss seo for image especially wordpress. The purpose of this image optimization is to speed up image loading in the article. In addition, the image that occupied the first page in search engines will bring the blog/website on the first page as well. I always recommend using images on every article even if only one picture. The following are the steps for image optimization.
1. Choose the Right File Name
Using the correct filename for an image affects SEO. Google will detect the filename in the image first before it detects any other attributes in the image. For example the picture you use is a picture of a rose garden then the file name for the image should you change like garden-flower.jpg and not garden.jpg or rose.jpg let alone HrtB1348.jpg, Make sure you’ve changed the image file name before in Uploaded to the website.
2. Use Appropriate Image With Article
If the article discusses the drone then input the drone image and not the camera or lens, and if the article discusses the soccer shoes then input the football shoe and not the soccer field or the football club logo. Always use relevant images and keep your own images, not images you take from other sites.If you do not have a picture for yourself or do not have a picture that matches what you discussed, you do not have to worry because it can use images from stock photos. Pictures from stock photos have creative commons like copyright and image usage rights, you should understand creative commons before using them, but I recommend using your own image.
3. Use the Right Image Size
The higher the image size on the image will make the image look more sharp. Image size is not too influential on search engine optimization, but the image size is too high will make the image becomes heavy when loading. You must reduce the image size or pixel in the image before entering the website. Use an image size of no more than 2500 pixels wide, for example 1280 × 853 pixels, 1920 × 1280 pixels, and 2400 × 1600 pixels.
4. Reduce File size In Fig
Fast loading times on websites are very good for user experience and it is one of important aspects for search engine optimization. Optimizing images for SEO by reducing file size is the way that is always done by SEO companies to help their clients. Do not be surprised if you find online tools or programs to reduce the size of the image without reducing the quality of the image. Use the file size on images up to 200kb, it would be better if it can be reduced again to under 100kb. Resize image file as small as possible. Is the reduced size of the file does not reduce the quality of the image as the image becomes slightly opaque? Yes, the image quality will decrease when the image size is reduced, as I said above there are some tools that can reduce the size of the image file without reducing the quality of the image.
5. Alt Text
Alt text entered into the image will be descriptive text when images on the website with any cause can not be seen by visitors. In situations like this usually visitors turn off the feature “show image” in the browser or the image does not appear due to a problem on the website. Make sure you add alt text including keywords to the image and give a description for the image.
Align is influential or not for search engine optimization is still ambiguous. There is a SEO specialist who states that the align image placed on the left or right and continued with the article content right beside the image is not good for search engine optimization. In other hand, many SEO specialist who stated that image alignment has no effect on search engine optimization. But I personally as an online article reader does not like to see the image that is on the side and continued with text beside the image so that the image is mixed with text. It is up to you.
7. XML Sitemap For Images
If you understand the steps to create a website for the website indexed by search engines, you definitely know what is the xml sitemap. The image also requires a sitemap to be submitted to google webmaster for images more easily indexed by google. Google describes the sitemaps image with detail. For wordpress users can use sitemaps image plugin, but unfortunately plugin to generate image sitemaps nothing is free.
8. Review the Image
After you have finished specifying the image, selecting the file name, reducing the file size, changing the image size, and entering the alt attribute, you should check the images as there may be typo in the description, alt attribute, and file name. This is done to make sure that you do not upload the original image. I have personal experience with this error.
