How to sign developed sites?

Question

PHP

Greetings, I develop websites and leave a modest link in the basement (what no advertising). I thought about protection so that it would not be possible to remove it, or at least make it difficult. so far I just came up with the idea of ​​inserting an ajax request to a file with a link into one of the scripts of the developed site itself. This ajax simply adds the received link to the footer. Are there already known solutions or ideas?

Answer 1

The only adequate option is a clause in the contract (for example, SAL does this).
If you are a freelancer, you can try verbal agreements (but it is clear that the client can change his mind at any time - and this is his right).
And for all the antics with hidden functionality, you have to fight off your hands.

Answer 2

It's easy to agree without a paper contract:
The format is simple: follow the terms and get privileges.
If the link is installed (and will be on the site in the agreed place and in the agreed form for the entire period), then you provide a free TP for fixing bugs for a period of one year and give a percentage discount for improvements.
Then there will be no point in removing the link from the Client, because She will give him privileges and bonuses.
And you - at any time you can monitor its presence and, if it is removed immediately, and then, before contacting, returned and immediately contact you - report non-compliance with the conditions and refuse free TP (+ cancel the discount for improvements).

Answer 3

No way.

Answer 4

if they want, they will figure out how to remove an unnecessary link. and the residue will remain.
it's better to negotiate.
and humans.txt

Answer 5

Humans.txt

Answer 6

Convey to the customer that your signature is an analogue of Rembrandt's signature, which will help others, his colleagues, when choosing a performer.
JS, of course, is interesting, but it will help more to control the health of a site taken for constant maintenance or monitoring.
In my practice, it was when the customer changed management and they decided to turn to competitors for improvements. At some point, my signature disappeared, I called the competitors - they returned the signature and put theirs next to mine.
The site has since changed drastically. Both externally and internally. Then I called the competitors a second time and they removed my signature, and I removed this site from my portfolio.
The best defense is to work in such a way that clients can brag: "look who developed my site!" :)

Do you like it if you buy a car and on the windshield there will be an inscription in large letters that this is a VASI car? when you are paid for a site, all rights to it are bought from you

Answer 8

I would have kicked for such a thing, such developers.

Answer 9

Let's start from afar.
By what right do you want to leave your link on the site that you have developed for the Client?
It is good practice for you to ask for permission to set up a link, if permission is granted, then at least for a while you will have a link to yourself.
If you are doing for a client, then this is his, not yours, and a link for good, you have no right to leave it there.
And now, based on the above, think about how to protect yourself from a negligent webmaster who wants to leave a link :) An example with a windshield, just in the subject :)

Answer 10

I remembered something when I was doing video filming of celebrations, some colleagues took money for the filming itself, for editing, and at the same time almost scratched DVDs with a nail so that the customer would not replicate them, because they agreed only, for example, on 2 copies .. .))
If in essence, copyright is the eternal theme of artisans) You, as an idea generator. you can claim copyright on your idea (unique design, ingenious code that has not been used anywhere before), but if you use handy tools that belong to other people to implement it (payment for working hours, investments are also included here), then they enter with you in related rights. And here, excuse me, move over - the share is 50/50. And your co-author has every right to refuse to place information about you on his half (on the finished product, because he ordered it).
So you have been advised correctly. You need to negotiate with your co-author, motivate him so that he does not have a desire to remove your link. The same technical support and refinement of your unique code, for which another developer will ask for a fabulous amount, because it will take a week to disassemble before implementing something.
And there is no super-duper means to protect your link, even if you establish a link between the client site and yours after twenty-five times the encoded code. From personal experience I can say that I had to pick out not such authorships, but this is already in the past ... :)
