Search engine optimization (SEO) is the process of making changes to your website so that it will appear higher in search engine results pages (SERPS). Due to Google's policy of not publishing their search algorithms, a large part of what we do is based on speculation and experimentation.
Your title tag is typically the first thing a potential visitor will take notice of when performing a search. Some common issues most make with page titles include:
Duplicating words in the page title
Not using keywords
Making your Page Title too long; 50-60 characters is typically all Google sees
The header tag (h1) will usually be the title of a post, or other emphasized text on the page. It will usually be the largest text that stands out. For the above Dropbox picture, the H1 tag would be "Put your creative energy to work, with Dropbox."
The h1 tag is the most important heading because it’s the highest level tag that shows what your specific page is about. Search engines generally give this tag more weight over other headings, so it usually improves your search engine ranking when you use it correctly.
This is the text version of a picture on your website so search engines can read the description to those that are visually impaired.
The main takeaway: Images with optimized alt text are more likely to populate in image search queries.
Assign alt tags to all images as you upload them.100 characters max.
Briefly describe the image and add in other important keywords when you have the space like your brand name or business-related keywords.
Optimize your pages toward specific keywords and integrate that page’s keyword in alt text.Don’t use “image of” or “picture of” – it’s a waste of space.
Be sure to apply alt text to site buttons images.If you’re running a multi-language site, apply necessary translated alt text.
Do not use the same title tag text as your alt text.
At a minimum, try to use natural language to describe an image. Write it like you would a page title for human readers, not search engines.
