For all, who want to make SEO themselves or simply want to just inform, here 25 tips for the search engine optimization by the professional:



Content is King:
The better the content is on its own, so the higher its quality, the better the page will be: regardless of the other ranking factors.



Meta title:
The meta tag "title" is very important and the favored keywords should be as far ahead as possible. Do not use more than 55 characters.


Meta description:
A meta description can be added with the "description" meta tag. It is important not to include the description with keywords.


Meta-Keywords:
Even if Google does not add more or less to the ranking, it shows the crawler what the website is about.


Headings:
The better the page is organized and the better the user is, the higher the page is usually on Google



Multimedia content:
Varied content such as pictures, videos, tables and so on make facts clear, which is also rewarded by Google



Meta-specifications for pictures:
In the case of pictures, the title, alt-text, width, and height should be indicated, but also no keyword stuffing.



Meta titles for links:
Whether external or internal links - meta titles show the bot what the link on the whole is.



Breadcrumb navigation:
A bread crumbs navigation helps the user very much on the website and makes for a better internal linking.



Internal link structure:
Each subpage of your own website should be easy to reach and linked sufficiently, both in navigation and in flow text.


Short URLs:
The shorter the URL, the easier it is for the user to remember it, and the Google crawler will also reward it


Duplicate Content:
Copying content from other pages is equivalent to an Ascension Commando - Google knows everything and punishes DC rigorously



PageSpeed:
The faster the website loads, the more convenient it can be used, even for the crawler, this can be an indication of quality.


Updates:
One page, just blogs, should be well maintained. Regularly adding new content is evidence of timeliness and is an important ranking factor.


Broken links:
Links that lead to nirvana are neither good for spiders nor for users and should be removed as soon as possible from the webmaster.



[b]High-quality backlinks[/b]
Backlinks without money keyword anchors and domains with high authority are one of the most important factors at all.


No link purchase:
Google is very good at debunking or spammed links, and the domains subsequently hard to punish.



NoFollow links:
Not all links should be do-follow since this creates an unsightly suspicion. About 10% no-follow is probably an ideal value.



Link positions
A link from the header of a page or from the upper section of a flowing text is considerably more value than a footer link.


Backlink age:
The older a backlink, the stronger it is because Google can assume that the linked site still has good content.



User Time:
The longer the site visitors stay on a website on average, the better the logical content is.



Comments:
If users use comments in a discussion, this is also a sign of high-quality content.



[b]Social signals:[/b]
Even if Facebook Likes or Tweets hardly play a role in the ranking, they can nevertheless direct user flows and thus indirectly provide advantages
[*]


[b]RSS feeds:[/b]
The more people who follow an offered RSS feed, the higher the probability that the information offered on the page is interesting
[*]


No over-optimization:
If you optimize your own website too much, you will be hit by Google and risk a penalty again.


These points can in no case replace a professional SEO consulting from an expert and serve merely to inform themselves about possible optimization tactics. If you want high-quality search engine optimization, which places a website on good placements over a longer period of time, you should be willing to spend money on it and hire a suitable agency.
