Although visual elements are important, Google still does not have mechanisms capable of satisfactorily identifying what an image is about. Therefore, it is necessary to add an alt tag — which is an alternative term that will be displayed if the page does not load properly — to help the search engine better understand the content of your page.
Additionally, users can reach your page by searching for images india mailing list on Google Images, as the search engine will identify that the visual content of your page corresponds to the user's search interests. Therefore, take the following recommendations into consideration:
Do not use long texts in the alt tag;
Add the keyword in the alt tag;
Do not do keyword stuffing (massive use of keywords);
Place captions close to visual content;
Save the image in the appropriate size so as not to overload the page;

Host the images on the same domain as your website.
Internal and external links
As mentioned previously, for content to be identified by users as reliable and of quality, it is important that it is based on authentic references. Therefore, whenever you mention data from a study to argue and prove what you are saying, it is important to add external links , which are those that direct the reader to the page that contains the information at the source.
In addition to qualifying the content, this strategy also ensures that search engines better position your post for users.
As for internal links, if you have cross-cutting themes on your blog about the content you are producing, add them, as readers who are interested in the topic will open the new page and stay longer on your blog, which is also evaluated by Google.
Backlinks and guest posts
Authority is an important factor considered by Google and it is measured through backlinks, which are external links from other websites that direct their audience to your page. Therefore, one way to secure these backlinks is by guest posting for other blogs, which is nothing more than writing content as a guest for another website.
Security Certificate (SSL)
Another SEO tip for blogs is to have SSL, as Google's search algorithm has taken this item into account since 2014. This certificate is what ensures that the personal data obtained by websites about their visitors remains secure against possible scams.
Furthermore, it is worth highlighting that this security tends to increase even more with the approval of the General Data Protection Law (LGPD), in 2018, which provides for the processing of personal data with the aim of guaranteeing protection of fundamental rights to privacy and freedom.
Page loading speed
If the user's permanence on the blog is a factor of relevance for Google's search engines, then having a page that loads quickly will provide a better experience for the visitor and, consequently, a better ranking.
Furthermore, Google's own algorithm identifies the loading speed of pages and prioritizes those that are faster.
