I meant "I do hesitate to give suggestions without being asked".
Similar to what @Buggritbuggrit wrote "utter ruthlessness". This doesn't mean being unkind, untruthful or disrespectful but be super sensitive to pink/red flags of any shades. A photo, or convo that makes you uneasy even if you can't put your finger on it; don't bother continuing getting to know the person. Single until your love interest makes it clear he has chosen to be committed to you for life. Circular or rotational dating. No premature intimacy. Everyone online is single until they tell you they're not seeing anyone else except you. I in turn didn't shed my singleness until I got the offer I wanted ie the person I was interested in told me he wanted to be monogamous with me for his lifetime and asked if I'll do same. I had tried other types of dating but they didn't give me the quality of relationship I wanted. My suggestion is not to drop one's single status until you're offered what you want especially in the areas of Monogamy, Continuity and Longevity.
Be on more than two sites and special interest ones if possible. Let your profile and photos reflect your personality, style and what you enjoy doing. A couple of full body and close up good quality photos.
Don't bother with 1st dates where the guy suggests/chooses locations closer to him or more convenient to him than you. Gentlemanly guys when asking for dates tend to ask what locations are good for me and what I'll like to do. I'll suggest two or three locations neighbouring my neighbourhood but no hint as to what to do. He gives two or three suggestions , I confirm I'm happy with them or one or two. Eg he suggests dinner, theatre or bowling for example(my profile had activities I enjoy either in my bio or photos). Coffee or quick drink can be better if I have reservations we'll get along. This happened rarely as I screened heavily. Two conversations or 4 exchanges and if he doesn't ask to meet then the probability of meeting is low. I don't chat unnecessarily. I'm warm and friendly in my replies but I don't try to keep the convo going in these early days or initiate. (I know three people who initiated and they are happily married). Many more I could write but people want different things and date differently and might not be ready for this. I'm sharing my own personal opinion and experience that helped achieve what I want. Happy to discuss further in PM. I have a master degree and my husband holds Phd (well known in his area)and we both have our own properties. I wanted a more traditional relationship/marriage. I wanted a man who would lead, be emotionally available, a provider, a Christian, intellectual, loving, kind, attentive, no children, never married etc. Yes, I had a long list and many would say very choosey but I know what I wanted my future to look like and I didn't wish to be in a relationship with any sign that it could cause me trauma. I lost my mum at 6 so unconditional love and a stable nuclear family is very important to me.
I enjoyed OLD and had really lovely dates. I didn't live in Central London at the time though we now do. If the guys come to locations convenient for you that makes it less "work" for you. You dress up and take a short 10 - 20 mins drive; at least for the first date. Some argue to meet half way between each other etc. For me, I felt the sort of man I want will be happy to make a longer journey to meet me and this was another way to weed out whiny ungentlemanly men.
I hope there's some info you'll find useful up there but more importantly that you meet the man of your dreams and have the relationship that gives you joy every single day. Don't give up, keep doing life, do the things that bring you joy; love is round the corner.
